Krylov-space anatomy and spread complexity of a disordered quantum spin chain
Bikram Pain, David E. Logan, Sthitadhi Roy
We investigate the anatomy and complexity of quantum states in Krylov space, in the ergodic and many-body localised (MBL) phases of a disordered, interacting spin chain. The Krylov…
Multifractality in high-dimensional graphs induced by correlated radial disorder
David E. Logan, Sthitadhi Roy
We introduce a class of models containing robust and analytically demonstrable multifractality induced by disorder correlations. Specifically, we investigate the statistics of eige…
The Fock-space landscape of many-body localisation
Sthitadhi Roy, David E. Logan
This article reviews recent progress in understanding the physics of many-body localisation (MBL) in disordered and interacting quantum many-body systems, from the perspective of e…
Localisation on certain graphs with strongly correlated disorder
Sthitadhi Roy, David E. Logan
Many-body localisation in interacting quantum systems can be cast as a disordered hopping problem on the underlying Fock-space graph. A crucial feature of the effective Fock-space…
