Role of bath-induced many-body interactions in the dissipative phases of the Su-Schrieffer-Heeger model
The Su-Schrieffer-Heeger chain is a prototype example of a symmetry-protected topological
insulator. Coupling it nonperturbatively to local thermal environments, either through the …

Antiferromagnetic order enhanced by local dissipation
We study an XXZ spin chain at zero magnetization coupled to a collection of local harmonic
