Challenges to observation of many-body localization
Piotr Sierant, Jakub Zakrzewski
We study time dynamics of 1D disordered Heisenberg spin-1/2 chain focusing on a regime of large system sizes and a long time evolution. This regime is relevant for observation of m…
Finite-Size scaling analysis of many-body localization transition in quasi-periodic spin chains
Adith Sai Aramthottil, Titas Chanda, Piotr Sierant +1
We analyze the finite-size scaling of the average gap-ratio and the entanglement entropy across the many-body localization (MBL) transition in one dimensional Heisenberg spin-chain…
Universal behavior beyond multifractality of wave-functions at measurement--induced phase transitions
Piotr Sierant, Xhek Turkeshi
We investigate the structure of many-body wave functions of 1D quantum circuits with local measurements employing the participation entropies. The leading term in system size depen…
On intermediate statistics across many-body localization transition
Bitan De, Piotr Sierant, Jakub Zakrzewski
The level statistics in the transition between delocalized and localized {phases of} many body interacting systems is {considered}. We recall the joint probability distribution for…
Dissipative Floquet Dynamics: from Steady State to Measurement Induced Criticality in Trapped-ion Chains
Piotr Sierant, Giuliano Chiriacò, Federica M. Surace +5
Quantum systems evolving unitarily and subject to quantum measurements exhibit various types of non-equilibrium phase transitions, arising from the competition between unitary evol…
Detecting ergodic bubbles at the crossover to many-body localization using neural networks
Tomasz Szoldra, Piotr Sierant, Korbinian Kottmann +2
The transition between ergodic and many-body localized phases is expected to occur via an avalanche mechanism, in which \emph{ergodic bubbles} that arise due to local fluctuations…
Constraints induced delocalization
Piotr Sierant, Eduardo Gonzalez Lazo, Marcello Dalmonte +2
We study the impact of quenched disorder on the dynamics of locally constrained quantum spin chains, that describe 1D arrays of Rydberg atoms in both frozen (Ising-type) and dresse…
