Current fluctuations in a gas of active Ornstein-Uhlenbeck particles
Sandeep Jangid, Aman Kumbhakar, Juliane U. Klamser +1
We investigate the statistics of the time-integrated current in an infinite one-dimensional gas of independent active Ornstein--Uhlenbeck particles, as a model system for studying…
A bottom-up approach to fluctuating hydrodynamics: Coarse-graining of stochastic lattice gases and the Dean-Kawasaki equation
Soumyabrata Saha, Sandeep Jangid, Thibaut Arnoulx de Pirey +2
Fluctuating hydrodynamics provides a quantitative, large-scale description of many-body systems in terms of smooth variables, with microscopic details entering only through a small…
Directed percolation transition to active turbulence driven by non-reciprocal forces
Juliane U. Klamser, Ludovic Berthier
We numerically study the collective dynamics of dense particle assemblies driven by non-reciprocal pairwise forces of amplitude . At a critical value , the system und…
Role of kinematic constraints in the time reversal symmetry breaking of a model active matter
Soumen Das, Shankar Ghosh, Tridib Sadhu +1
Active-matter systems are inherently out-of-equilibrium and perform mechanical work by utilizing their internal energy sources. Breakdown of time-reversal symmetry (BTRS) is a hall…
Emerging mesoscale flows and chaotic advection in dense active matter
Yann-Edwin Keta, Juliane Klamser, Robert L. Jack +1
We study two models of overdamped self-propelled disks in two dimensions, with and without aligning interactions. Active mesoscale flows leading to chaotic advection emerge in both…
Sequence of phase transitions in a model of interacting rods
Juliane U. Klamser, Tridib Sadhu, Deepak Dhar
In a system of interacting thin rigid rods of equal length on a two-dimensional grid of lattice spacing , we show that there are multiple phase transitions as the coupl…
Kinetic Monte-Carlo Algorithms for Active-Matter systems
Juliane U. Klamser, Olivier Dauchot, Julien Tailleur
We study kinetic Monte-Carlo (KMC) descriptions of active particles. By relying on large discrete time steps, KMC algorithms accelerate the relaxational dynamics of active systems…
A kinetic-Monte Carlo perspective on active matter
Juliane U. Klamser, Sebastian C. Kapfer, Werner Krauth
We study non-equilibrium phases for interacting two-dimensional self-propelled particles with isotropic pair-wise interactions using a persistent kinetic Monte Carlo (MC) approach.…
Multiple singularities of the equilibrium free energy in a one-dimensional model of soft rods
Sushant Saryal, Juliane U. Klamser, Tridib Sadhu +1
There is a misconception, widely shared amongst physicists, that the equilibrium free energy of a one-dimensional classical model with strictly finite-ranged interactions, and at n…
Thermodynamic phases in two-dimensional active matter
Juliane U. Klamser, Sebastian C. Kapfer, Werner Krauth
Active matter has been intensely studied for its wealth of intriguing properties such as collective motion, motility-induced phase separation (MIPS), and giant fluctuations away fr…
