Many-body localization in periodically driven systems.

We consider disordered many-body systems with periodic time-dependent Hamiltonians in one spatial dimension. By studying the properties of the Floquet eigenstates, we identify two distinct phases: (i) a many-body localized (MBL) phase, in which almost all eigenstates have area-law entanglement entropy, and the eigenstate thermalization hypothesis (ETH) is violated, and (ii) a delocalized phase,...

Many-body localization phase transition

We use exact diagonalization to explore the many-body localization transition in a random-field spin-1/2 chain. We examine the correlations within each many-body eigenstate, looking at all high-energy states and thus effectively working at infinite temperature. For weak random field the eigenstates are thermal, as expected in this nonlocalized, “ergodic” phase. For strong random field the eigen...

Many-body localization in dipolar systems.

Systems of strongly interacting dipoles offer an attractive platform to study many-body localized phases, owing to their long coherence times and strong interactions. We explore conditions under which such localized phases persist in the presence of power-law interactions and supplement our analytic treatment with numerical evidence of localized states in one dimension. We propose and analyze s...

On Energy Differences in Many Body Systems

Given two nearby lying states of a m a n y b o d y system, each one involving m a n y one-par t ic le contributions, it would be very inconvenient to express the difference of the energies of these states as a difference of absolute energy values. Small errors in the absolute values could drast ical ly change the d i f ference. In cases where the energies are inf in i te , their difference make...

Energy transduction in periodically driven non-hermitian systems.

We show a new mechanism to extract energy from nonequilibrium fluctuations typical of periodically driven non-Hermitian systems. The transduction of energy between the driving force and the system is revealed by an anomalous behavior of the susceptibility, leading to a diminution of the dissipated power and consequently to an improvement of the transport properties. The general framework is ill...
