Spectra and strong decays of open charm-bottom tetraquarks in an unequal-mass Born-Oppenheimer framework
Bowen Kang, Xi Xia, Tao Guo
We investigate the mass spectra and strong decay channels of -wave open charm-bottom () tetraquarks within the Born-Oppenheimer approximation. Exte…
Honeycomb Crystal in a Mass-Asymmetric Electron-Hole Bilayer
Shengdu Chai, Wangqian Miao, Yuqiang Li +3
A two-dimensional electron gas in a uniform neutralizing background forms a triangular Wigner crystal at low density. In a strongly mass-asymmetric electron-hole bilayer, localized…
Artificial moiré engineering for an ideal BHZ model
Wangqian Miao, Arman Rashidi, Xi Dai
We demonstrate that (001) grown Cd3As2 thin films with a superlattice-patterned gate can potentially realize the moiré Bernevig-Hughes-Zhang (BHZ) model. Our calculations identify…
Moiré optical phonons dancing with heavy electrons in magic-angle twisted bilayer graphene
Hao Shi, Wangqian Miao, Xi Dai
Electron-phonon coupling in magic-angle twisted bilayer graphene is an important but difficult topic. We propose a scheme to simplify and understand this problem. Weighted by the c…
Engineering the in-plane anomalous Hall effect in CdAs thin films
Wangqian Miao, Binghao Guo, Susanne Stemmer +1
We predict two topological phase transitions for cadmium arsenide (\ce{Cd3As2}) thin films under in-plane magnetic field, taking advantage of a four-band model and effec…
Probing superconducting phase fluctuations from the current noise spectrum of pseudogaped metal-superconductor tunnel junctions
Xi Dai, Tao Xiang, Tai-Kai Ng +1
We study the current noise spectra of a tunnel junction of a metal with strong pairing phase fluctuation and a superconductor. It is shown that there is a characteristic peak in th…
