Observing Algebraic Variety of Lee-Yang Zeros in Asymmetrical Systems via a Quantum Probe
Arijit Chatterjee, T S Mahesh, Mounir Nisse +1
Lee-Yang (LY) zeros, points on the complex plane of physical parameters where the partition function goes to zero, have found diverse applications across multiple disciplines like…
Thermal Drude weight in an integrable chiral clock model
Sandipan Manna, G J Sreejith
We calculate the finite temperature thermal conductivity of a time-reversal invariant chiral clock model along an integrable line in the parameter space using tDMRG.…
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…
Dichotomous acceleration process in one dimension: Position fluctuations
Ion Santra, Durgesh Ajgaonkar, Urna Basu
We study the motion of a one-dimensional particle which reverses its direction of acceleration stochastically. We focus on two contrasting scenarios, where the waiting-times betwee…
A sluggish random walk with subdiffusive spread
Aniket Zodage, Rosalind J. Allen, Martin R. Evans +1
We study a one-dimensional sluggish random walk with space-dependent transition probabilities between nearest-neighbour lattice sites. Motivated by trap models of slow dynamics, we…
Many universality classes in an interface model restricted to non-negative heights
Peter Grassberger, Deepak Dhar, P. K. Mohanty
We present a simple one dimensional stochastic model with three control parameters and a surprisingly rich zoo of phase transitions. At each (discrete) site and time , an in…
Symmetric Exclusion Process under Stochastic Power-law Resetting
Seemant Mishra, Urna Basu
We study the behaviour of a symmetric exclusion process in the presence of non-Markovian stochastic resetting, where the configuration of the system is reset to a step-like profile…
Continuous Gated First-Passage Processes
Yuval Scher, Aanjaneya Kumar, M. S. Santhanam +1
Gated first-passage processes, where completion depends on both hitting a target and satisfying additional constraints, are prevalent across various fields. Despite their significa…
Inference from gated first-passage times
Aanjaneya Kumar, Yuval Scher, Shlomi Reuveni +1
First-passage times provide invaluable insight into fundamental properties of stochastic processes. Yet, various forms of gating mask first-passage times and differentiate them fro…
Universal framework for record ages under restart
Aanjaneya Kumar, Arnab Pal
We propose a universal framework to compute record age statistics of a stochastic time-series that undergoes random restarts. The proposed framework makes minimal assumptions on th…

Sandipan Mohanta, Madhumita Saha, B. Prasanna Venkatesh +1
For a four-stroke asymmetrically driven quantum Otto engine with working medium modeled by a single qubit, we study the bounds on non-equilibrium fluctuations of work and heat. We…
Spontaneous collective transport in a heat--bath
Mayank Sharma, A. Bhattacharyay
We investigate emergence of spontaneous filtering of Brownian motion in higher dimensional space by many--body structures of symmetry broken dimer. Interacting dimer form structure…
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…
Counting statistics of energy transport across squeezed thermal reservoirs

A general formalism for computing the full counting statistics of energy exchanged between 'N' squeezed thermal photon reservoirs weakly coupled to a cavity with 'M' photon modes i…
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…
The phase transition from nematic to high-density disordered phase in a system of hard rods on a lattice
Aagam Shah, Deepak Dhar, R. Rajesh
A system of hard rigid rods of length on hypercubic lattices is known to undergo two phases transitions when chemical potential is increased: from a low density isotropic phase…
Finite-size scaling functions of the phase transition in the ferromagnetic Ising model on random regular graphs
Suman Kulkarni, Deepak Dhar
We discuss the finite-size scaling of the ferromagnetic Ising model on random regular graphs. These graphs are locally tree-like, and in the limit of large graphs, the Bethe approx…
Energy transport in Z3 chiral clock model
Naveen Nishad, G J Sreejith
We characterize the energy transport in a one dimensional chiral clock model. The model generalizes the symmetric transverse field Ising model (TFIM).…
Spontaneous layering and power-law order in the three-dimensional fully-packed hard-plate lattice gas
G. Rakala, D. Mandal, S. Biswas +3
We obtain the phase diagram of fully-packed hard plates on a cubic lattice. Each plate covers an elementary plaquette of the cubic lattice and occupies its four vertices, with each…

D. Mandal, G. Rakala, K. Damle +2
We study the phase diagram of a system of hard plates on the three dimensional cubic lattice, {\em i.e.} a lattice gas of plates that each cover an elementary p…
