Mechanical pressure and momentum conservation in dry active matter

open access: yes, 2017
We relate the breakdown of equations of states for the mechanical pressure of generic dry active systems to the lack of momentum conservation in such systems. We show how sources and sinks of momentum arise generically close to confining walls.

Room impulse response reconstruction with physics-informed deep learning

open access: yesThe Journal of the Acoustical Society of America
A method is presented for estimating and reconstructing the sound field within a room using physics-informed neural networks. By incorporating a limited set of experimental room impulse responses as training data, this approach combines neural network processing capabilities with the underlying physics of sound propagation, as articulated by the wave ...

Leonardo da Vinci: Cause, effect, linearity, and memory

open access: yesJournal of Advanced Research, 2018
In this contribution, some textual portions of the Leonardo da Vinci’s work were analyzed with the aim to highlight how, moving from Aristotle and going beyond him, he combines the intermediate positions that, from the Greek philosopher, passing through ...

Probing short-range correlations in the deuteron via incoherent diffractive J/ψ production with spectator tagging at the EIC

open access: yesPhysics Letters B, 2020
Understanding the role of Quantum Chromodynamics in generating nuclear forces is important for uncovering the mechanism of short-ranged nuclear interactions and their manifestation in short range correlations (SRC). The future Electron-Ion-Collider (EIC)

The spatio-temporal structure of impulse-generated azimuthalsmall-scale Alfvén waves interacting with high-energy chargedparticles in the magnetosphere [PDF]

open access: yesAnnales Geophysicae, 2004
It is assumed to date that the energy source of azimuthal small-scale ULF waves in the magnetosphere (azimuthal wave numbers m≧1) is provided by the energetic particles interacting with the waves through the bounce-drift resonance.

Chromodynamic Lensing and Transverse Single Spin Asymmetries

open access: yes, 2003
We illustrate how an axial asymmetry in impact parameter dependent parton distributions can give rise to an axial asymmetry for the transverse momentum of the leading quark in the photo-production of hadrons.

Electron-deuteron scattering in a relativistic theory of hadrons [PDF]

open access: yes, 1998
We review a three-dimensional formalism that provides a systematic way to include relativistic effects including relativistic kinematics, the effects of negative-energy states, and the boosts of the two-body system in calculations of two-body bound ...

Dynamically assisted tunneling in the impulse regime

open access: yesPhysical Review Research, 2021
We study the enhancement of tunneling through a potential barrier V(x) by a time-dependent electric field with special emphasis on pulse-shaped vector potentials such as A_{x}(t)=A_{0}/cosh^{2}(ωt). In addition to the known effects of preacceleration and
