Quantum geometry of singlet superconductors
David Porlles, Wei Chen
We elaborate that -wave and -wave superconductors described by mean field theories possess a nontrivial quantum geometry. From the overlap of two quasihole states at slightly…
Tomasch Oscillations as Above-Gap Signature of Topological Superconductivity
Antonio Štrkalj, Xi-Rong Chen, Wei Chen +2
The identification of topological superconductors usually involves searching for in-gap modes that are protected by topology. However, in the current experimental settings, the smo…
Anomalous Hall effect in type-I Weyl metals beyond the noncrossing approximation
Jia-Xing Zhang, Wei Chen
We study the anomalous Hall effect (AHE) in tilted Weyl metals with Gaussian disorder due to the crossed X and Ψ diagrams in this work. The importance of such diagrams to the AHE h…
Searching for Unconventional Superfluid in Excitons of Monolayer Semiconductors
Wei Chen, Chun-Jiong Huang, Qizhong Zhu
It is well known that two-dimensional (2D) bosons in homogeneous space cannot undergo real Bose-Einstein condensation, and the superfluid to normal phase transition is Berezinskii-…
Optical absorption measurement of spin Berry curvature and spin Chern marker
Wei Chen
In two-dimensional time-reversal symmetric topological insulators described by Dirac models, the topological invariant can be described by the spin Chern number.…
Proximity-induced zero-energy states indistinguishable from topological edge states
Igor J. Califrer, Poliana H. Penteado, J. Carlos Egues +1
When normal metals (NMs) are attached to topological insulators or topological superconductors, it is conceivable that the quantum states in these finite adjacent materials can int…
