Anomalous and regular transport in spin 1/2 chains: AC conductivity
Ramsés J. Sánchez, Vipin Kerala Varma, Vadim Oganesyan
We study magnetization transport in anisotropic spin- chains governed by the integrable XXZ model with and without integrability-breaking perturbations at high temperatures ($…
Massively parallel implementation and approaches to simulate quantum dynamics using Krylov subspace techniques
Marlon Brenes, Vipin Kerala Varma, Antonello Scardicchio +1
We have developed an application and implemented parallel algorithms in order to provide a computational framework suitable for massively parallel supercomputers to study the unita…
Finite-size anomalies of the Drude weight: role of symmetries and ensembles
Ramsés J. Sánchez, Vipin Kerala Varma
We revisit the subtelties of computing the high temperature spin stiffness of the spin- XXZ chain using exact diagonalization to analyze its dependence on system symmetrie…
Fractality in nonequilibrium steady states of quasiperiodic systems
Vipin Kerala Varma, Clélia de Mulatier, Marko Znidaric
We investigate the nonequilibrium response of quasiperiodic systems to boundary driving. In particular we focus on the Aubry-André-Harper model at its metal-insulator transition an…
