Non-Hermitian Numerical Renormalization Group: Solution of the non-Hermitian Kondo model
Phillip C. Burke, Andrew K. Mitchell
Non-Hermitian (NH) Hamiltonians describe open quantum systems, nonequilibrium dynamics, and dissipative processes. Although a rich range of single-particle NH physics has been unco…

Topological phases of the interacting Su-Schrieffer-Heeger model: An analytical study
E. Di Salvo, A. Moustaj, C. Xu +4
The interacting SSH model provides an ideal ground to study the interplay between topologically insulating phases and electron-electron interactions. We study the polarization dens…
