Emergence of large quantum oscillation frequencies in thin flakes of the kagome superconductor CsVSb
W. Zhang, Lingfei Wang, Chun Wai Tsang +5
Kagome metals AVSb~(A = K, Rb, Cs) are recently discovered platforms featuring an unusual charge-density-wave (CDW) order and superconductivity. The electronic band structu…
The Ground State Lattice Distortion of CsVSb Revealed by de Haas-van Alphen Oscillations
Senyang Pan, Feng Du, Yong Zhang +10
The recently discovered AVSb (A = K, Rb, Cs) compounds have garnered intense attention in the scientific community due to their unique characteristics as kagome superco…
Krylov complexity, mode-resolved complexity and entanglement entropy across phase transitions in the non-Hermitian extended Su-Schrieffer-Heeger model
Ling-Feng Zhang, Wing Chi Yu
We investigate phase transitions in the extended Su-Schrieffer-Heeger (SSH) model with next-nearest-neighbor hoppings and an imaginary staggered chemical potential. In the presence…
Density Matrix Spectra and Order Parameters in the 1D Extended Hubbard Model
Wing Chi Yu, Shi-Jian Gu, Hai-Qing Lin
Without any knowledge of the symmetry existing in the system, we derive the exact forms of the order parameters which show long-range correlation in the ground state of the one-dim…
Current direction dependent magnetotransport in CuTe
Ying Kit Tsui, C. N. Kuo, C. E. Hsu +7
Despite being a layered, easily-exfoliated compound, copper monotelluride (CuTe) features an unusual quasi-one-dimensional charge density wave below K. With…
Novel Approach to Unveil Quantum Phase Transitions Using Fidelity Map
Ho-Kin Tang, Mohamad Ali Marashli, Wing Chi Yu
Fidelity approach has been widely used to detect various types of quantum phase transitions, including some that are beyond the Landau symmetry breaking theory, in condensed matter…
