We prove the existence of nonequilibrium phases of matter in the prethermal regime of
periodically driven, long-range interacting systems, with power-law exponent α> d, where d …

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 …

We introduce topological invariants for gapless systems and study the associated boundary
phenomena. More generally, the symmetry properties of the low-energy conformal field …

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 …

It is well-known that symmetry-protected topological (SPT) phases can be obtained from the
trivial phase by an entangler, a finite-depth unitary operator $ U $. Here, we consider …

Results are presented for the dynamics of an almost strong edge mode which is the
quasistable Majorana edge mode occurring in nonintegrable spin chains. The dynamics of …

Symmetry protected topological (SPT) phases are one of the simplest, yet nontrivial, gapped
systems that go beyond the Landau paradigm. In this work, we study an extension of the …

Topology is a fascinating phenomena in condensed-matter physics typically associated with
a bulk gap. However, recent research shifts focus to quantum critical points or phases that …

Almost strong edge-mode operators arising at the boundaries of certain interacting one-
dimensional symmetry protected topological phases with Z 2 symmetry have infinite …

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 …
