Moiré pattern of spin liquid and Neel magnet in a Kitaev chain
R. Wang, P. Wang, K. L. Zhang +1
A moiré pattern occurs when two periodic structures in a system have a slight mismatch period, resulting the coexistence of distinct phases in different large-scale spacial regions…
Robustness of the pumping charge to dynamic disorder
R. Wang, Z. Song
We investigate the effect of disorder on a gapped crystalline system by introducing a class of local quantities for an energy band, which is referred as to band correlation functio…
Quantum-critical scale invariance in a transition metal alloy
Y. Nakajima, T. Metz, C. Eckberg +14
Quantum-mechanical fluctuations between competing phases at induce exotic finite-temperature collective excitations that are not described by the standard Landau Fermi liquid…
Dynamical topological invariant for non-Hermitian Rice-Mele model
R. Wang, X. Z. Zhang, Z. Song
We study a non-Hermitian Rice-Mele model without breaking time-reversal symmetry, with the non-Hermiticity arising from imbalanced hopping rates. The Berry connection, Berry curvat…
