Many-body localization (MBL) is an emergent phase in correlated quantum systems with promis- ing applications, particularly in quantum information. Here, we unveil the existence and analyse this phase in a chiral multiferroic model system. Conventionally, MBL occurrence is traced via level statistics by implementing a standard finite-size scaling procedure. Here, we present an approach based on the full distribution of the ratio of adjacent energy spacings. We find a strong broadening of the…

Beyond many-body localized states in a spin-disordered Hubbard model
A prime characterization of many-body localized (MBL) systems is the entanglement of their eigenstates; in contrast to the typical ergodic phase whose eigenstates are volume law, MBL eigenstates obey
Non-equilibrium processes and ergodicity-breaking in isolated quantum systems
In this thesis we consider isolated quantum systems influenced by disorder and external driving, and explore aspects of localisation and ergodicity-breaking in three different models. We first
Universal Properties of Many-Body Localization Transitions in Quasiperiodic Systems.
TLDR
This real-space RG calculation shows that MBL transitions in 1D QP systems are characterized by the critical exponent ν≈2.4, which respects the Harris-Luck bound (ν>1/d) for QP Systems and satisfies theHarris-Chayes-Chayses-Fisher-Spencer bound for random systems.
Exact dynamics of concurrence-based entanglement in a system of four spin-1/2 particles on a triangular ladder structure
Motivated by the ability of triangular spin ladders to implement quantum information processing, we propose a type of such systems whose Hamiltonian includes the XX Heisenberg interaction on the
Spin-1/2 XY chain magnetoelectric: Effect of zigzag geometry
A spin-1/2 $XY$ chain model of magnetoelectric on a zigzag chain is considered rigorously. The magnetoelectric coupling is described within the Katsura-Nagaosa-Balatsky mechanism. In the zigzag

TLDR
It is shown that the growth rate of the OTOC for the canonically conjugate coordinates of the oscillator is able to capture the Lyapunov exponent in the chaotic regime, which is supported by a system independent effective random matrix model.
Entanglement dynamics and fractional quantum state transport in the spin-12 triangular plaquette
The dramatic growth of research areas within the province of quantum state transmission (QST) is rapidly accelerating. An important insight to understand the process of QST can be fulfilled by
