Fermions on a 1D lattice: localized sources and sinks with dephasing
Elka Bhattacharya, Sushant Saryal, Soumya Ghosh +1
We study a general one-dimensional spinless fermionic system subject to a localized source, sink, and bulk dephasing. Within the Lindblad framework, we compute the time evolution o…
Cusp singularities in the distribution of orientations of asymmetrically-pivoted hard discs on a lattice
Sushant Saryal, Deepak Dhar
We study a system of equal-sized circular discs each with an asymmetrically placed pivot at a fixed distance from the center. The pivots are fixed at the vertices of a regular tria…
Exact Results for Interacting Hard Rigid Rotors on a d-Dimensional Lattice
Sushant Saryal, Deepak Dhar
We study the entropy of a set of identical hard objects, of general shape, with each object pivoted on the vertices of a d-dimensional regular lattice of lattice spacing a, but can…
Universal bounds on fluctuations for machines with broken time-reversal symmetry
Sushant Saryal, Sandipan Mohanta, Bijay Kumar Agarwalla
For a generic class of machines with broken time-reversal symmetry we show that in the linear response regime the relative fluctuation of the sum of output currents for time-forwar…
Universal bounds on cooling power and cooling efficiency for autonomous absorption refrigerators
Sandipan Mohanta, Sushant Saryal, Bijay Kumar Agarwalla
For steady-state autonomous absorption refrigerators operating in the linear response regime, we show that there exists a hierarchy between the relative fluctuation of currents for…
Bounds on fluctuations for finite-time quantum Otto cycle
Sushant Saryal, Bijay Kumar Agarwalla
For finite-time quantum Otto heat engine with working fluid consisting of either a (i) qubit or (ii) a harmonic oscillator, we show that the relative fluctuation of output work is…
Universal Bounds on Fluctuations in Continuous Thermal Machines
Sushant Saryal, Matthew Gerry, Ilia Khait +2
We study bounds on ratios of fluctuations in steady-state time-reversal heat engines controlled by multi affinities. In the linear response regime, we prove that the relative fluct…
Thermodynamic uncertainty relation for energy transport in transient regime -- Model study
Sushant Saryal, Onkar Sadekar, Bijay Kumar Agarwalla
We investigate transient version of the recently discovered thermodynamic uncertainty relation (TUR) which provides a precision-cost trade-off relation for certain out-of-equilibri…
Experimental study of the thermodynamic uncertainty relation
Soham Pal, Sushant Saryal, Dvira Segal +2
A cost-precision trade-off relationship, the so-called thermodynamic uncertainty relation (TUR), has been recently discovered in stochastic thermodynamics. It bounds certain thermo…
Thermodynamic uncertainty relation in thermal transport
Sushant Saryal, Hava Friedman, Dvira Segal +1
We use the fundamental nonequilibrium steady-state fluctuation symmetry and derive a condition on the validity of the thermodynamic uncertainty relation (TUR) in thermal transport…
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…
