Multiple quantum Mpemba effect: exceptional points and oscillations
Amit Kumar Chatterjee, Satoshi Takada, Hisao Hayakawa
We explore the role of exceptional points and complex eigenvalues on the occurrence of the quantum Mpemba effect. To this end, we study a two-level driven dissipative system subjec…
Quantum Mpemba effect in a quantum dot with reservoirs
Amit Kumar Chatterjee, Satoshi Takada, Hisao Hayakawa
We demonstrate the quantum Mpemba effect in a quantum dot coupled to two reservoirs, described by the Anderson model. We show that the system temperatures starting from two differe…
Classical and quantum facilitated exclusion processes
Amit Kumar Chatterjee, Adhip Agarwala
We demonstrate exciting similarities between classical and quantum many body systems whose microscopic dynamics are composed of non-reciprocal three-site facilitated exclusion proc…
Counter-flow induced clustering: Exact results
Amit Kumar Chatterjee, Hisao Hayakawa
We analyze the cluster formation in a non-ergodic stochastic system as a result of counter-flow, with the aid of an exactly solvable model. To illustrate the clustering, a two spec…
Multi species asymmetric simple exclusion process with impurity activated flips
Amit Kumar Chatterjee, Hisao Hayakawa
We obtain an exact matrix product steady state for a class of multi species asymmetric simple exclusion process with impurities, under periodic boundary condition. Alongside the us…
Dynamical regimes of finite temperature discrete nonlinear Schrödinger chain
Amit Kumar Chatterjee, Manas Kulkarni, Anupam Kundu
We show that the one dimensional discrete nonlinear Schrödinger chain (DNLS) at finite temperature has three different dynamical regimes (ultra-low, low and high temperature regime…
Spatio-temporal spread of perturbations in a driven dissipative Duffing chain: an OTOC approach
Amit Kumar Chatterjee, Anupam Kundu, Manas Kulkarni
Out-of-time-ordered correlators (OTOC) have been extensively used as a major tool for exploring quantum chaos and also recently, there has been a classical analogue. Studies have b…
Assisted exchange models in one dimension
Amit Kumar Chatterjee, P. K. Mohanty
We introduce an assisted exchange model (AEM) on a one dimensional periodic lattice with (K+1) different species of hard core particles, where the exchange rate depends on the pair…
Negative Differential Mobility in Interacting Particle Systems
Amit Kumar Chatterjee, Urna Basu, P. K. Mohanty
Driven particles in presence of crowded environment, obstacles or kinetic constraints often exhibit negative differential mobility (NDM) due to their decreased dynamical activity.…
Phase coexistence and spatial correlations in reconstituting k-mer models
Amit Kumar Chatterjee, Bijoy Daga, P. K. Mohanty
In reconstituting k-mer models, extended objects which occupy several sites on a one dimensional lattice, undergo directed or undirected diffusion, and reconstitute -when in contac…
Cluster-factorized steady states in finite range processes
Amit Chatterjee, Punyabrata Pradhan, P. K. Mohanty
We study a class of nonequilibrium lattice models on a ring where particles hop in a particular direction, from a site to one of its (say, right) nearest neighbours, with a rate th…
