The many-body localised (MBL) to thermal crossover observed in exact diagonalisation
studies remains poorly understood as the accessible system sizes are too small to be in an …

It is a classic result that certain interacting integrable spin chains host robust edge modes
known as strong zero modes (SZMs). In this Letter, we extend this result to the Floquet …

Integrable Floquet spin chains are known to host strong zero and π modes which are
boundary operators that respectively commute and anticommute with the Floquet unitary …

Topological order offers possibilities for processing quantum information that can be
immune to imperfections. However, the question of its stability out of equilibrium is relevant …

Floquet spin chains have been a venue for understanding topological states of matter that
are qualitatively different from their static counterparts by, for example, hosting π edge …

The stability and dynamics of almost strong zero and π modes in weakly nonintegrable
Floquet spin chains are investigated. Such modes can also be viewed as localized …

We study how symmetry can enrich strong-randomness quantum critical points and phases,
and lead to robust topological edge modes coexisting with critical bulk fluctuations. These …

Results are presented for the dynamics of edge modes in interacting Floquet Ising chains. It
is shown that in addition to the quasistable 0 and π edge modes, a third long lived edge …

The transverse field Ising model (TFIM) on the half-infinite chain possesses an edge zero
mode. This work considers an impurity model: TFIM perturbed by a boundary integrability …

Formation of quantum scars in many-body systems provides a novel mechanism for
enhancing coherence of weakly entangled states. At the same time, coherence of edge …
