Conference Object Citation - Scopus: 2Spacecraft Accelerometry With Parametric Nanoamplifiers Pumped by Radiation-Induced Dispersion Force Modulation(Institute of Electrical and Electronics Engineers Inc., 2023) Pinto, F.In this paper, we discuss new results about the behavior and performance of a novel class of highly sensitive accelerometers previously proposed by the author. The initial motivation for this effort is a technological-push, demand-pull stemming from efforts to achieve a drastic reduction in spacecraft mass and volume needed for the deployment of CubeSat class vehicles to the Moon and Mars, while enabling such vehicles to independently survive by obtaining accurate navigation data during critical mission phases. The device discussed herein is a nano-electromechanical system operating under the simultaneous action of a harmonic electrostatic force and of a Casimir force modulated in time by illumination so as to realize a mechanical parametric amplifier. The analysis is based on original numerical simulations of the nonlinear resonance response of the proof mass while accelerating with respect to an inertial reference frame. © 2023 IEEE.Article Citation - WoS: 2Citation - Scopus: 1Efimov Physics in Curved Spacetime: Field Fluctuations and Exotic Matter(World Scientific Publ Co Pte Ltd, 2018) Pinto, FabrizioSeveral experimental detections have demonstrated the existence of Borromean states predicted by Vitaly Efimov within a nuclear physics context, that is, trimers bound despite the absence of bound states of any of the two-body subsystems. I show that novel Efimov Physics is expected in gravitationally polarizable nonbaryonic dark matter beyond the Standard Model with van der Waals-like forces driven by quantum gravitational fluctuations. I also discuss ground and space-based tests of spacetime curvature effects on weakly bound, highly diffuse quantum three-body systems with standard electrodynamical van der Waals forces. Finally, I consider exotic gravitational quantum matter from higher-order Brunnian structures and analogies with classical systems, already proven in three-stranded DNA, driven by the stochastic gravitational wave background.Conference Object Citation - WoS: 1Citation - Scopus: 1Advances in the Formulation of Minimal Thermodynamically Consistent Models for Dispersion Force-Driven High-Accuracy Inertial Nano-Sensors(IEEE, 2025) Pinto, FabrizioWe present advances in the accurate multiphysics modeling of nano-accelerometers motivated by the specific navigational requirements of small spacecraft under low thrust in interplanetary missions. The process of energy transfer to the nanodevice via parametric coupling is analyzed from the thermodynamical standpoint. The system is based on simultaneous electrostatic excitation and on van der Waals forces modulated by laser radiation acting as a parametric pump. It is shown that the processes involved rigorously satisfy the First and Second Laws of Thermodynamics. This proof paves the way for the design of thermodynamically consistent models of this novel class of nano-accelerometers.Review Article Citation - WoS: 3Citation - Scopus: 1Gravitational Dispersion Forces and Gravity Quantization(Mdpi, 2021) Pinto, FabrizioThe parallel development of the theories of electrodynamical and gravitational dispersion forces reveals important differences. The former arose earlier than the formulation of quantum electrodynamics so that expressions for the unretarded, van der Waals forces were obtained by treating the field as classical. Even after the derivation of quantum electrodynamics, semiclassical considerations continued to play a critical role in the interpretation of the full results, including in the retarded regime. On the other hand, recent predictions about the existence of gravitational dispersion forces were obtained without any consideration that the gravitational field might be fundamentally classical. This is an interesting contrast, as several semiclassical theories of electrodynamical dispersion forces exist although the electromagnetic field is well known to be quantized, whereas no semiclassical theory of gravitational dispersion forces was ever developed although a full quantum theory of gravity is lacking. In the first part of this paper, we explore this evolutionary process from a historical point of view, stressing that the existence of a Casimir effect is insufficient to demonstrate that a field is quantized. In the second part of the paper, we show that the recently published results about gravitational dispersion forces can be obtained without quantizing the gravitational field. This is done first in the unretarded regime by means of Margenau's treatment of multipole dispersion forces, also obtaining mixed potentials. These results are extended to the retarded regime by generalizing to the gravitational field the approach originally proposed by McLachlan. The paper closes with a discussion of experimental challenges and philosophical implications connected to gravitational dispersion forces.Article Graviton Creation by the Dynamical Casimir Effect in Inspiraling Neutron Star Systems(World Scientific Publ Co Pte Ltd, 2025) Pinto, FabrizioIt is shown that the exceedingly dense interiors of neutron stars can act as moving gravitational wave-reflecting boundaries in an optical cavity. The orbital motion of the mergers causes a gravitational dynamical Casimir effect, with consequent creation of gravity quanta from the vacuum and parametric amplification of the graviton flux. The challenges and limitations of the model are discussed, along with realistic observation and detection strategies.Conference Object Citation - Scopus: 2Dispersion Force Engineering. The Long Path From Hooked Atoms to Next-Generation Spacecraft(Elsevier, 2022) Pinto, FabrizioABSTRACT This paper presented as a Keynote talk is one of a series by the author analyzing in depth different inter-related aspects of the evolution of our understanding of intermolecular forces from a key speculation within early atomistic philosophy to applications in modern industry products, such as the atomic force microscope (AFM), non-volatile memory elements (NRAM), and "gecko-glue" adhesives. The manner in which dispersion force engineering as an emerging general purpose technology is enabling breakthrough advances in spacecraft performance and extreme space vehicle miniaturization is the overall topic of this paper series.(c) 2021 Elsevier Ltd.

In order to do work, nano-machines enabled by dispersion forces must exchange energy with the surrounding environment. Such processes can be described in terms of thermodynamical engine cycles involving individual atoms or material boundaries, separated by possibly empty gaps and interacting via time-dependent dispersion forces. The fundamental strategy indispensable to achieve dispersion force time-modulation, demonstrated experimentally by independent groups on different scales, is based on the illumination of interacting, semiconducting elements by appropriate radiation beams. Here we analyze the operation of ideal nano-engines in the quasi-static regime by means of the Lifshitz theory of dispersion forces involving semiconducting boundary or atom irradiation. Firstly, we verify that the First Law of Thermodynamics is satisfied so that the total energy of the system is rigorously conserved. Secondly, we show that, within this first approximate treatment, the Second Law of Thermodynamics may be violated for extremely small interboundary gap widths. We identify important limitations to be addressed to determine whether this is a reliable conclusion. The technological and historic backdrops are presented, and important topics for future research are identified.Conference Object Citation - WoS: 6Citation - Scopus: 7Casimir Forces: Fundamental Theory, Computation, and Nanodevice Applications(Springer, 2018) Pinto, FabrizioSeventy years after submission to the Physical Review of the crucial quantum electrodynamical treatment of interatomic dispersion forces by Casimir and Polder, our understanding of such interactions in both the unretarded and retarded regimes has undergone a dramatic and intricate evolution. In this contribution, we explore the ultimate physical motivations leading to this fascinating trajectory rich in momentous implications for the goal of both fabrication and operation of highly integrated micro-and nano-structures. The first and most obvious development has been the growing appreciation that, far from only representing a weak, though exotic, effect, Casimir's zero point pressure of electromagnetic waves between two conducting parallel planes is actually a dominant interaction on the nanoscale. This resulted in Feynman's unforgettable caricature - in There's plenty of room at the bottom - of van der Waals forces between microparts as a man with his hands full of molasses, which led to such forces being understood as the leading cause of undesirable stiction for several decades. However, commencing in the 1980s, the realization that such strong dispersion interactions might offer unique technological opportunities surfaced. The second thrust was connected to the discovery that, unlike expected from London's intermolecular force theory and the naive assumption of additivity, dispersion forces depend quite unpredictably on topology and on the interplay of dielectric properties of the interacting media. This may lead to drastic departures from results obtained through perturbative methods and indeed to the prediction, later verified both in the unretarded and retarded regimes, that dispersion forces may become repulsive. The challenge of computing Casimir forces in more general geometries different from that of two parallel planes has led to substantial progress from the numerical standpoint although open problems remain. Lastly, in one of the earliest and most significant discoveries in the history of the field, it was shown that dispersion forces can be modulated in time, for instance by illumination in semiconductors. This discovery opened the way to consideration of thermodynamical engine cycles enabled by Casimir forces and to a novel, highly effective means for energy transfer on the nanoscale.Book Part Citation - WoS: 5Citation - Scopus: 6The Future of Van Der Waals Force-Enabled Technology Transfer Into The Aerospace Marketplace(Elsevier Science Bv, 2019) Pinto, Fabrizio[Abstract Not Available]Conference Object Citation - Scopus: 2Gravimetry by Nanoscale Parametric Amplifiers Driven by Radiation-Induced Dispersion Force Modulation(Springer Science and Business Media Deutschland GmbH, 2023) Pinto, FabrizioHere we present early results from lumped-element numerical simulations of a novel class of nano electromechanical systems (NEMS) presently being considered for ground-based gravimetry and future micro accelerometry applications in GPS-denied environments, including spacecraft. The strategy we discuss is based on measuring the effects of non-inertial or gravitational forces on the dynamics of a standard oscillator driven at its resonance frequency by a time-dependent electrostatic potential. In order to substantially enhance the sensitivity of the instrument, the oscillating mass is made to simultaneously interact with a nearby boundary so as to be affected by quantum electrodynamical Casimir forces. Furthermore, unlike previously published proposals, in the design presented herein the Casimir boundary does not oscillate but it is a fixed semiconducting layer. As already demonstrated experimentally, this arrangement enables Casimir force time-modulation by semiconductor back-illumination. Such a design strategy, first suggested by this author as a promising approach to gravitational wave detection in different nano-sensors, allows for the realization of a Casimir force-pumped mechanical parametric amplifier. Such devices can, in principle, yield gains of several orders of magnitude in the mechanical response amplitude over the response from standard unpumped oscillators. The numerical proof-of-concept first presented herein points to a potentially new class of gravimetry products based on exploiting appropriately engineered dispersion forces as an emerging enabling general purpose technology on the nanoscale. © 2022, The Author(s).
