Passive objects in a chiral active bath: from micro to macro
Cory Hargus, Federico Ghimenti, Julien Tailleur +1
We present a detailed derivation of the Langevin dynamics obeyed by a massive rigid body immersed in a chiral active bath. We show how the antisymmetric nature of the noise leads t…
Irreversible swap algorithms for soft sphere glasses
Yoshihiko Nishikawa, Federico Ghimenti, Ludovic Berthier +1
We extend to soft repulsive interaction potentials a recently proposed irreversible swap algorithm originally designed for polydisperse hard spheres. The original algorithm perform…
Odd dynamics of passive objects in a chiral active bath
Cory Hargus, Federico Ghimenti, Julien Tailleur +1
When submerged in a chiral active bath, a passive object becomes a spinning ratchet imbued with odd transport properties. We present the most general Langevin dynamics for a rigid…
Clever algorithms for glasses work by time reparametrization
Federico Ghimenti, Ludovic Berthier, Jorge Kurchan +1
The ultraslow dynamics of glass-formers has been explained by two views considered as mutually exclusive: one invokes locally hindered mobility, the other rests on the complexity o…
Monte Carlo simulations of glass-forming liquids beyond Metropolis
Ludovic Berthier, Federico Ghimenti Frédéric van Wijland
Monte Carlo simulations are widely employed to measure the physical properties of glass-forming liquids in thermal equilibrium. Combined with local Monte Carlo moves, the Metropoli…
Irreversible Boltzmann samplers in dense liquids: weak-coupling approximation and mode-coupling theory
Federico Ghimenti, Ludovic Berthier, Grzegorz Szamel +1
Exerting a nonequilibrium drive on an otherwise equilibrium Langevin process brings the dynamics out of equilibrium but can also speedup the approach to the Boltzmann steady-state.…
Transverse forces and glassy liquids in infinite dimensions
Federico Ghimenti, Ludovic Berthier, Grzegorz Szamel +1
We explore the dynamics of a simple liquid whose particles, in addition to standard potential-based interactions, are also subjected to transverse forces preserving the Boltzmann d…
Irreversible Monte Carlo algorithms for hard disk glasses: from event-chain to collective swaps
Federico Ghimenti, Ludovic Berthier, Frédéric van Wijland
Equilibrium sampling of the configuration space in disordered systems requires algorithms that bypass the glassy slowing down of the physical dynamics. Irreversible Monte Carlo alg…
Shear-Induced Phase Behavior and Topological Defects in Two-Dimensional Crystals
Federico Ghimenti, Misaki Ozawa, Giulio Biroli +1
We investigate through numerical simulations how a two-dimensional crystal yields and flows under an applied shear. We focus over a range that allows us to both address the respons…
Sampling efficiency of transverse forces in dense liquids
Federico Ghimenti, Ludovic Berthier, Grzegorz Szamel +1
Sampling the Boltzmann distribution using forces that violate detailed balance can be faster than with the equilibrium evolution, but the acceleration depends on the nature of the…
Accelerating, to some extent, the -spin dynamics
Federico Ghimenti, Frédéric van Wijland
We consider a detailed-balance violating dynamics whose stationary state is a prescribed Boltzmann distribution. Such dynamics have been shown to be faster than any equilibrium cou…
