20-22.02.2024 - Workshop on Quantum Simulators of the Future: From Dynamical Gauge Fields to Lattice Gauge Theories | (smr 3922)

An ICTP Meeting This Workshop will gather world-leading groups that design, realize, and characterize a new generation of simulators with ultracold atoms and beyond. It will address novel quantum simulators of statistical gauge fields, dynamical lattices, and lattice gauge theory models (LGT), as well as connections to quantum computing and tensor network methods. https://indico.ictp.it/event/10460

We study many-body localization (MBL) transition in disordered Kicked Ising model using a polynomially filtered exact diagonalization (POLFED) algorithm. We quantitatively demonstrate that finite size effects at the MBL transition in disordered Kicked Ising model are less severe than in random field XXZ spin chains widely studied in the context of MBL. This allows us to observe consistent signatures of the transition to MBL phase for a several indicators of ergodicity breaking. We show that an assumption a power-law divergence of the correlation length at the MBL transition yields a critical exponent ν ≈ 2, consistent with the Harris criterion for 1D disordered systems.
