Charge imprinting biases topology of correlated insulator in hBN-aligned rhombohedral multilayer graphene

Lei Qiao, Xin Lu, Fu-Chun Zhang +1

Rhombohedral multilayer graphene aligned with hexagonal boron nitride (RMG-hBN) hosts correlated Chern phases, but the microscopic role of hBN stacking remains unclear, especially…

Jahn-Teller distortion on strained La $_{3}$ Ni $_{2}$ O $_{7}$ thin films

Yuxin Wang, Zhan Wang, Fu-Chun Zhang +1

We present a systematic study of the electronic structure of strained La $_{3}$ Ni $_{2}$ O $_{7}$ thin films. We show that biaxial compressive strain mainly elongates the outer apical Ni-O b…

Orbital-Selective $d$ -wave Superconductivity in the Two-Band $t$ - $J$ Model: Possible Applications to La $_{3}$ Ni $_{2}$ O $_{7}$

Zhan Wang, Kun Jiang, Fu-Chun Zhang +1

We investigate superconductivity in a two-band $t$ - $J$ model consisting of an itinerant orbital (orbital-0) and a quasi-localized orbital (orbital-1) using variational Monte Carlo.…

Time-Reversal Symmetry Breaking Superconducting State and Collective Modes in Kagome Superconductors

Xinloong Han, Jun Zhan, Jiangping Hu +2

We comprehensively study the unconventional pairing and collective modes in the multiband kagome superconductors AV $_{3}$ Sb $_{5}$ (A= $K, Cs, Rb$ ). By solving g…

Yamaji effect and quantum oscillation in Yang-Rice-Zhang model of underdoped cuprates

Yicheng Zhong, Fu-Chun Zhang, Kun Jiang

Recent experiments have revealed signatures of small Fermi pockets in the pseudogap phase of cuprate superconductors, most notably the Yamaji effect observed in $\mathrm{HgBa}_2\ma…
