Push-sum Distributed Dual Averaging for Convex Optimization in Multi-agent Systems with Communication Delays
Cong Wang, Shengyuan Xu, Deming Yuan +2
The distributed convex optimization problem over the multi-agent system is considered in this paper, and it is assumed that each agent possesses its own cost function and communica…
Growth of mutual information in a quenched one-dimensional open quantum many body system
Somnath Maity, Souvik Bandyopadhyay, Sourav Bhattacharjee +1
We study the temporal evolution of the mutual information (MI) in a one-dimensional Kitaev chain, coupled to a fermionic Markovian bath, subsequent to a global quench of the chemic…
One-dimensional quantum many body systems with long-range interactions
Somnath Maity, Utso Bhattacharya, Amit Dutta
The presence of algebraically decaying long-range interactions may alter the critical as well as topological behaviour of a quantum many-body systems. However, when the interaction…
Fibonacci steady states in a driven integrable quantum system
Somnath Maity, Utso Bhattacharya, Amit Dutta +1
We study an integrable system that is reducible to free fermions by a Jordan-Wigner transformation which is subjected to a Fibonacci driving protocol based on two non-commuting Ham…
Critical phase boundaries of static and periodically kicked long-range Kitaev chain
Utso Bhattacharya, Somnath Maity, Amit Dutta +1
We study the static and dynamical properties of a long-range Kitaev chain, i.e., a -wave superconducting chain in which the superconducting pairing decays algebraically as $1/l^…
The fate of current, residual energy and entanglement entropy in aperiodic driving of one dimensional Jordan Wigner integrable models
Somnath Maity, Utso Bhattacharya, Amit Dutta
We investigate the dynamics of two Jordan Wigner solvable models, namely, the one dimensional chain of hard-core bosons (HCB) and the one-dimensional transverse field Ising model u…
Exact results in Floquet coin toss for driven integrable models
Utso Bhattacharya, Somnath Maity, Uddipan Banik +1
We study an integrable Hamiltonian reducible to free fermions which is subjected to an imperfect periodic driving with the amplitude of driving (or kicking) randomly chosen from a…
