Unusual ergodic and chaotic properties of trapped hard rods
Debarshee Bagchi, Jitendra Kethepalli, Vir B. Bulchandani +4
We investigate ergodicity, chaos and thermalization for a one-dimensional classical gas of hard rods confined to an external quadratic or quartic trap, which breaks microscopic int…
Nonequilibrium spin transport in integrable and non-integrable classical spin chains
Dipankar Roy, Abhishek Dhar, Herbert Spohn +1
Anomalous transport in low dimensional spin chains is an intriguing topic that can offer key insights into the interplay of integrability and symmetry in many-body dynamics. Recent…
Boltzmann entropy of a freely expanding quantum ideal gas
Saurav Pandey, Junaid Majeed Bhat, Abhishek Dhar +5
We study the time evolution of the Boltzmann entropy of a microstate during the non-equilibrium free expansion of a one-dimensional quantum ideal gas. This quantum Boltzmann entrop…
