Negative temperature states as exact equilibrium solutions of the Wave Kinetic equation for one dimensional lattices
M. Onorato, G. Dematteis, D. Proment +3
We predict negative temperature states in the Discrete Nonlinear Schödinger equation as exact solutions of the associated Wave Kinetic equation. Those solutions are consistent with…
Coexistence of ballistic and Fourier regimes in the -FPUT lattice
Giovanni Dematteis, Lamberto Rondoni, Davide Proment +2
Commonly, thermal transport properties of one-dimensional systems are found to be anomalous. Here, we perform a numerical and theoretical study of the -FPUT chain, considered a…
Clustering and phase transitions in a 2D superfluid with immiscible active impurities
Umberto Giuriato, Giorgio Krstulovic, Davide Proment
Phase transitions of a finite-size two-dimensional quantum fluid of bosons in presence of impurities are studied by using the truncated Gross-Pitaevskii model. Impurities are descr…
A kinetic theory for age-structured stochastic birth-death processes
Chris D. Greenman, Tom Chou
Classical age-structured mass-action models such as the McKendrick-von Foerster equation have been extensively studied but they are structurally unable to describe stochastic fluct…
Shaking-induced crystallization of dense sphere packings
D. P. Shinde, Anita Mehta, G. C. Barker
We use a hybrid Monte Carlo algorithm to simulate the shaking of spheres at different vibrational amplitudes, and find that spontaneous crystallisation occurs in specific dynamical…
Multi-particle structures in non-sequentially reorganized hard sphere deposits
Luis A. Pugnaloni, G. C. Barker, Anita Mehta
We have examined extended structures, bridges and arches, in computer generated, non-sequentially stabilized, hard sphere deposits. The bridges and arches have well defined distrib…
