High-temperature spin dynamics in the Heisenberg chain: Magnon propagation and emerging KPZ-scaling in the zero-magnetization limit
Felix Weiner, Peter Schmitteckert, Soumya Bera +1
The large-scale dynamics of quantum integrable systems is often dominated by ballistic modes due to the existence of stable quasi-particles. We here consider as an archetypical exa…
Sub-diffusion in the Anderson model on random regular graph
Giuseppe De Tomasi, Soumya Bera, Antonello Scardicchio +1
We study the finite-time dynamics of an initially localized wave-packet in the Anderson model on the random regular graph (RRG). Considering the full probability distribution $Π(x,…
Insights on heterogeneity in blinking mechanisms and non-ergodicity using sub-ensemble statistical analysis of single quantum-dots
Amitrajit Mukherjee, Korak Kumar Ray, Chinmay Phadnis +3
Photo-luminescence intermittency (blinking) in semiconductor nanocrystals (NCs), a phenomenon ubiquitous to single-emitters, is generally considered to be temporally random intensi…
Slow dynamics and strong finite-size effects in many-body localization with random and quasi-periodic potential
Felix Weiner, Ferdinand Evers, Soumya Bera
We investigate charge relaxation in disordered and quasi-periodic quantum-wires of spin-less fermions (-model) at different inhomogeneity strength in the localized and n…
