Inner non-Hermitian skin effect on Bethe lattice
Junsong Sun, Chang-An Li, Shiping Feng +1
We investigate the non-Hermitian Su-Schrieffer-Heeger (SSH) model on Bethe lattice, revealing a novel localization phenomenon coined inner non-Hermitian skin effect. This effect is…
Non-Hermitian Quantum Fractals
Junsong Sun, Chang-An Li, Qingyang Guo +5
The first quantum fractal discovered in physics is the Hofstadter butterfly. It stems from large external magnetic fields. We discover instead a new class of non-Hermitian quantum…
Low-temperature T resistivity in the underdoped pseudogap phase versus T-linear resistivity in the overdoped strange-metal phase of cuprate superconductors
Xingyu Ma, Minghuan Zeng, Huaiming Guo +1
The transport experiments demonstrate a dramatic switch from the low-temperature linear in temperature (T-linear) resistivity in the overdoped strange-metal phase of cuprate superc…
Exact Demonstration of pair-density-wave superconductivity in the -Hubbard model
Xingchuan Zhu, Junsong Sun, Shou-Shu Gong +4
Describing and achieving `unconventional' superconductivity remains a forefront challenge in quantum many-body physics. Here we use a unitary mapping, combined with the well-establ…
Anomalous impurity effect in the heavy-fermion superconductor CeCu2Si2
Shan Zhao, Weifu Liu, Yi-feng Yang +2
Recent observations of contradictory impurity effect in the heavy-fermion superconductor CeCu2Si2 at ambient pressure have hindered the identification of its pairing symmetry. Here…
Quasiparticle scattering interference in cuprate superconductors
Minghuan Zeng, Xiang Li, Yongjun Wang +1
The quasiparticle scattering interference (QSI) is intimately related to the nature of the quasiparticle and of its interplay with a variety of electronic orders and superconductiv…
