Preparation of a Quantum Spin Liquid in Non-Hermitian Quantum Dimer Models and Rydberg Arrays
Shashwat Chakraborty, Taylor L. Hughes
We identify an unconventional form of the non-Hermitian skin effect that occurs not in position space but in many-body Fock space, which we call the Fock space skin effect (FSSE).…
Chern Dartboard Superconductors
Rebecca Chan, Taylor L. Hughes
We investigate the interplay of particle-hole symmetry and sub-Brillouin zone (sBZ) topology by coupling a so-called Chern dartboard insulator (CDI) to a superconductor (SC) via th…
No-go theorem for single time-reversal invariant symmetry-protected Dirac fermions in 3+1d
Lei Gioia, Anton A. Burkov, Taylor L. Hughes
We employ a general method, known as anomaly-matching, to derive new no-go theorems of fermionic lattice models. For our main result, we show that time-reversal invariant 3+1d latt…
Giant non-reciprocity and gyration through modulation-induced Hatano-Nelson coupling in integrated photonics
Ogulcan E. Orsel, Jiho Noh, Penghao Zhu +4
Asymmetric energy exchange interactions, also known as Hatano-Nelson type couplings, enable the study of non-Hermitian physics and associated phenomena like the non-Hermitian skin…
