gravitational wave detectors as particle physics laboratories constraining scalar Interactions with a coherent inspiral model of boson star binaries
Physical Review D, 2020Co-Authors: Costantino Pacilio, Massimo Vaglio, Andrea Maselli, Paolo PaniAbstract:Gravitational-wave (GW) detections of binary neutron star coalescences play a crucial role to constrain the Microscopic Interaction of matter at ultrahigh density. Similarly, if boson stars exist in the universe, their coalescence can be used to constrain the fundamental coupling constants of a scalar field theory. We develop the first coherent waveform model for the inspiral of boson stars with quartic Interactions. The waveform includes coherently spin-induced quadrupolar and tidal-deformability contributions in terms of the masses and spins of the binary and of a single coupling constant of the theory. We show that future instruments, such as the Einstein Telescope and the Laser Interferometer Space Antenna, can provide strong complementary bounds on bosonic self-Interactions while the constraining power of current detectors is marginal.

the kardar parisi zhang equation as scaling limit of weakly asymmetric interacting brownian motions
Communications in Mathematical Physics, 2017Co-Authors: Joscha Diehl, Massimiliano Gubinelli, Nicolas PerkowskiAbstract:We consider a system of infinitely many interacting Brownian motions that models the height of a one-dimensional interface between two bulk phases. We prove that the large scale fluctuations of the system are well approximated by the solution to the KPZ equation provided the Microscopic Interaction is weakly asymmetric. The proof is based on the martingale solutions of Goncalves and Jara (Arch Ration Mech Anal 212(2):597–644, 2014) and the corresponding uniqueness result of Gubinelli and Perkowski (Energy solutions of KPZ are unique, 2015).

framework of grinding process modeling and simulation based on Microscopic Interaction analysis
Robotics and Computer-integrated Manufacturing, 2011Co-Authors: Yiming RongAbstract:This paper describes a framework of grinding process modeling to understand the grinding fundamentals and design grinding processes with predictive performance. The model regards grinding process as a time dependent process and an integration of Microscopic Interactions in the wheel-workpiece contact zone, including cutting, plowing, and sliding as well as other frictional Interactions. The grinding process control and design are in fact to manage and balance all these Interactions. The principles of Microscopic Interactions are analyzed and used to correlate the grinding process input parameters and performance output.

Energy transfer in Tm,Ho:KYW crystal and diode-pumped microchip laser operation
2020Co-Authors: Kurilchik S., Gusakova N., Demesh M., Yasukevich A., Pavlyuk A., Kuleshov N.Abstract:© 2016 Optical Society of America.An investigation of Tm-Ho energy transfer in Tm(5at.%),Ho(0.4at.%):KYW single crystal by two independent techiques was performed. Based on fluorescence dynamics measurements, energy transfer parameters P71 and P28 for direct (Tm→Ho) and back (Ho→Tm) transfers, respectively, as well as equilibrium constant Θ were evaluated. The obtained results were supported by calculation of Microscopic Interaction parameters according to the Förster-Dexter theory for a dipoledipole Interaction. Diode-pumped continuous-wave operation of Tm,Ho:KYW microchip laser was demonstrated, for the first time to our knowledge. Maximum output power of 77 mW at 2070 nm was achieved at the fundamental TEM00 mode
