Quantum Annealing: An Overview
Atanu Rajak, Sei Suzuki, Amit Dutta +1
In this review, after providing the basic physical concept behind quantum annealing (or adiabatic quantum computation), we present an overview of some recent theoretical as well as…
Late-time critical behavior of local string-like observables under quantum quenches
Souvik Bandyopadhyay, Anatoli Polkovnikov, Amit Dutta
In recent times it has been observed that signatures of equilibrium quantum criticality surprisingly show up in many-body systems which are manifestly far from equilibrium. We expl…
Disconnected entanglement entropy as a marker of edge modes in a periodically driven Kitaev chain
Saikat Mondal, Diptiman Sen, Amit Dutta
We study the disconnected entanglement entropy (DEE) of a Kitaev chain in which the chemical potential is periodically modulated with -function pulses within the framework of Fl…
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…
Convergence Rates of Decentralized Gradient Methods over Cluster Networks
Amit Dutta, Nila Masrourisaadat, Thinh T. Doan
We present an analysis for the performance of decentralized consensus-based gradient (DCG) methods for solving optimization problems over a cluster network of nodes. This type of n…
