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…
Detecting topological phase transitions through entanglement between disconnected partitions in a Kitaev chain with long-range interactions
Saikat Mondal, Souvik Bandyopadhyay, Sourav Bhattacharjee +1
We explore the behaviour of the disconnected entanglement entropy (DEE) across the topological phases of a long range interacting Kitaev chain where the long range interactions dec…
Quasi-localization dynamics in a Fibonacci quantum rotor
Sourav Bhattacharjee, Souvik Bandyopadhyay, Amit Dutta
We analyze the dynamics of a quantum kicked rotor (QKR) driven with a binary Fibonacci sequence of two distinct drive amplitudes. While the dynamics at low drive frequencies is fou…
Driven quantum many-body systems and out-of-equilibrium topology
Souvik Bandyopadhyay, Sourav Bhattacharjee, Diptiman Sen
In this review we present some of the work done in India in the area of driven and out-of-equilibrium systems with topological phases. After presenting some well-known examples of…
