DOI: 10.1039/d2tc05100a
Abstract: The increase in ergodicity in BFO–xSTO is correlated with a weak ferroelectric response. The increased disorder induces a non-ergodic ground state, preventing the classic ferroelectric crossover. read more here.

DOI: 10.1103/physrevb.101.245107
Abstract: The presence of quantum scars, athermal eigenstates of a many-body Hamiltonian with finite energy density, leads to absence of ergodicity and long-time coherent dynamics in closed quantum systems starting from simple initial states. Such non-ergodic… read more here.

DOI: 10.1103/physrevb.96.041122
Abstract: The many-body localized (MBL) phase is characterized by a complete set of quasi-local integrals of motion and area-law entanglement of excited eigenstates. We study the effect of non-Abelian continuous symmetries on MBL, considering the case… read more here.

DOI: 10.1193/081716eqs135m
Abstract: Probabilistic seismic hazard analyses are usually performed with semi-empirical ground motion models (GMMs) following the ergodic assumption whereby average source, path, and site effects from global databases apply for a specific site of interest. Site-specific… read more here.

DOI: 10.3390/e25050739
Abstract: We propose and discuss two variants of kinetic particle models—cellular automata in 1 + 1 dimensions—that have some appeal due to their simplicity and intriguing properties, which could warrant further research and applications. The first… read more here.
