Controlling Liouvillian topological phases via Hamiltonian band topology under chiral symmetry
Shu Long, Hong-Sen Yin, Chao Yang +3
We establish a direct connection between Hamiltonian band topology and the Liouvillian spectral winding of open quantum systems with quadratic dissipations. This allows the band to…

Dissipation-Driven Transition of Particles from Dispersive to Flat Bands
Yutao Hu, Chao Yang, Yucheng Wang
Flat bands (FBs) play a crucial role in condensed matter physics, offering an ideal platform to study strong correlation effects and enabling applications in diffraction-free photo…
