Photon antibunching in a cavity-QED system with two Rydberg-Rydberg interaction atoms
Tong Huang, Lei Tan
We propose how to achieve strong photon antibunching effect in a cavity-QED system coupled with two Rydberg-Rydberg interaction atoms. Via calculating the equal time second order c…
Metal-insulator transition and dominant pairing symmetry in twisted bilayer graphene
Wanying Chen, Yonghuan Chu, Tongyun Huang +1
Motivated by recent experimental studies that have found signatures of a correlated insulator phase and tuning superconductivity in twisted bilayer graphene, we study the temperatu…
Antiferromagnetically ordered Mott insulator and superconductivity in twisted bilayer graphene: A quantum Monte carlo study
Tongyun Huang, Lufeng Zhang, Tianxing Ma
Using exact quantum Monte Carlo method, we examine the recent novel electronic states seen in magic-angle graphene superlattices. From the Hubbard model on a double-layer honeycomb…
Zitterbewegung in time-reversal Weyl Semimetals
Tongyun Huang, Tianxing Ma, Li-Gang Wang
We perform a systematic study of the Zitterbewegung effect of fermions, which are described by a Gaussian wave with broken spatial-inversion symmetry in a three-dimensional low-ene…
