Suppression of one-dimensional weak localization by band asymmetry
Kartikeya Arora, Rajeev Singh, Pavan Hosur
We investigate disorder-induced localization in metals that break time-reversal and inversion symmetries through their energy dispersion, , but lack Berry phases.…
Effect of long-range hopping and interactions on entanglement dynamics and many-body localization
Rajeev Singh, Roderich Moessner, Dibyendu Roy
We numerically investigate the dynamics of entanglement in a chain of spinless fermions with nonrandom but long-range hopping and interactions, and with random on-site energies. Fo…
Signatures of the many-body localization transition in the dynamics of entanglement and bipartite fluctuations
Rajeev Singh, Jens H. Bardarson, Frank Pollmann
The many-body localization transition is a dynamical quantum phase transition between a localized and an extended phase. We study this transition in the XXZ model with disordered m…
Probing Many-Body Localization by Spin Noise Spectroscopy
Dibyendu Roy, Rajeev Singh, Roderich Moessner
We propose to apply spin noise spectroscopy (SNS) to detect many-body localization (MBL) in disordered spin systems. The SNS methods are relatively non-invasive technique to probe…
Extreme variability in convergence to structural balance in frustrated dynamical systems
Rajeev Singh, Subinay Dasgupta, Sitabhra Sinha
In many complex systems, the dynamical evolution of the different components can result in adaptation of the connections between them. We consider the problem of how a fully connec…
Large variability in dynamical transitions in biological systems with quenched disorder
Jinshan Xu, Rajeev Singh, Nicolas Garnier +2
Coherent oscillatory activity can arise spontaneously as a result of increased coupling in a system of excitable and passive cells, each being quiescent in isolation. This can pote…
