Spectral Lyapunov exponents in chaotic and localized many-body quantum systems
Amos Chan, Andrea De Luca, J. T. Chalker
We consider the spectral statistics of the Floquet operator for disordered, periodically driven spin chains in their quantum chaotic and many-body localized phases (MBL). The spect…
Many-body delocalisation as symmetry breaking
S. J. Garratt, J. T. Chalker
We present a framework in which the transition between a many-body localised (MBL) phase and an ergodic one is symmetry breaking. We consider random Floquet spin chains, expressing…
Local pairing of Feynman histories in many-body Floquet models
S. J. Garratt, J. T. Chalker
We study many-body quantum dynamics using Floquet quantum circuits in one space dimension as simple examples of systems with local interactions that support ergodic phases. Physica…
Emergent moments and random singlet physics in a Majorana spin liquid
S. Sanyal, K. Damle, J. T. Chalker +1
We exhibit an exactly solvable example of a SU(2) symmetric Majorana spin liquid phase, in which quenched disorder leads to random-singlet phenomenology. More precisely, we argue t…
Quantum Hall network models as Floquet topological insulators
Andrew C. Potter, J. T. Chalker, Victor Gurarie
Network models for equilibrium integer quantum Hall (IQH) transitions are described by unitary scattering matrices, that can also be viewed as representing non-equilibrium Floquet…
