Dynamical signatures of Hardcore-Boson Supersolid on the Triangular Lattice
Xingchuan Zhu, Qingyang Guo, Junsong Sun +6
We investigate the dynamical signatures of the supersolid phase in the triangular-lattice hardcore Bose-Hubbard model via large-scale quantum Monte Carlo simulations and linear spi…
Impurity-Scattering Assisted Umklapp Scattering as the Origin of Low-Temperature Resistivity in the Normal-State of Cuprate Superconductors
Xingyu Ma, Minghuan Zeng, Huaiming Guo +1
The transport experiments reveal that the low-temperature resistivity in the normal-state of cuprate superconductors is quadratic in temperature (T-quadratic) in the underdoped pse…
Altermagnetism and its induced higher-order topology on the Lieb lattice
Xingmin Huo, Xingchuan Zhu, Chang-An Li +4
Altermagnetism (AM) has brought renewed attention to the Lieb lattice. Here, we broaden the scope of altermagnetic models on the Lieb lattice by using a general scheme based on spi…
Unusual electronic ordering in the pseudogap phase of underdoped cuprate superconductors
Xiang Li, Minghuan Zeng, Yu Lan +2
The pseudogap phase of the underdoped cuprate superconductors harbours diverse manifestations of different ordered electronic-states, and then these ordered electronic-states coexi…
Unusual electronic structure in underdoped cuprate superconductors
Xiang Li, Minghuan Zeng, Huaiming Guo +1
The underdoped cuprate superconductors are characterized by the opening of the pseudogap, while such an aspect of the pseudogap effect should be reflected in the low-energy electro…
Geometric Superfluid Weight in Quasicrystals
Junsong Sun, Huaiming Guo, Bohm-Jung Yang
We study the geometric contribution to the superfluidity in quasicrystals in which the conventional momentum-space quantum geometric tensor cannot be defined due to the lack of tra…
Marginal Metals and Kosterlitz-Thouless Type Phase Transition in Disordered Altermagnets
Chang-An Li, Bo Fu, Huaiming Guo +2
Altermagnetism, a recently discovered magnetic phase characterized by spin-split bands without net magnetization, has emerged as promising platform for novel physics and potential…
Design of altermagnetic models from spin clusters
Xingchuan Zhu, Xingmin Huo, Shiping Feng +3
Altermagnetism, a new class of collinear compensated magnetic phase, has garnered tremendous interest because of its rich physics and promising applications. Physical models and ve…
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…
Klein-bottle quadrupole insulators and Dirac semimetals
Chang-An Li, Junsong Sun, Song-Bo Zhang +2
The Benalcazar-Bernevig-Hughes (BBH) quadrupole insulator model is a cornerstone model for higher-order topological phases. It requires π-flux threading through each plaquette of t…
Topological invariant in three-dimensional band insulators with disorder
H. -M. Guo
Topological insulators in three dimensions are characterized by a Z2-valued topological invariant, which consists of a strong index and three weak indices. In the presence of disor…
