Observation of Emergent Spacetime Supersymmetry at Superconducting Quantum Criticality
Zi-Xiang Li, Abolhassan Vaezi, Christian B. Mendl +1
No definitive evidence of spacetime supersymmetry (SUSY) that transmutes fermions into bosons and vice versa has been revealed in nature so far. Moreover, whether spacetime SUSY in…
Edge stability and edge quantum criticality in 2D interacting topological insulators
Zi-Xiang Li, Hong Yao
Robustness of helical edge states in 2D topological insulators (TI) against strong interactions remains an intriguing issue. Here, by performing the first sign-free quantum Monte C…
Symmetry protected topological Luttinger liquids and the phase transition between them
Hong-Chen Jiang, Zi-Xiang Li, Alexander Seidel +1
We show that a doped spin-1/2 ladder with antiferromagnetic intra-chain and ferromagnetic inter-chain coupling is a symmetry protected topologically non-trivial Luttinger liquid. T…
