Disorder-induced diffusion transport in flat-band systems with quantum metric
Chun Wang Chau, Tian Xiang, Shuai A. Chen +1
Our previous understanding of transport in disordered system depends on the assumption that there is a well-defined Fermi velocity. The Fermi velocity determines important length s…
Geometric Frustration Assisted Kinetic Ferromagnetism in Doped Mott Insulators
Qianqian Chen, Shuai A. Chen, Zheng Zhu
Understanding ferromagnetism mechanism in doped Mott insulators on frustrated lattices remains challenging at intermediate coupling and finite doping. Here, we study the itinerant…
Flat-band Fulde-Ferrell-Larkin-Ovchinnikov State from Quantum Geometric Discrepancy
Zi-Ting Sun, Ruo-Peng Yu, Shuai A. Chen +2
We propose a new scheme for realizing Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) Cooper pairing states within flat bands, in contrast to the conventional paradigm such as the Zeeman e…
Superconductivity from Quasiparticle Pairing of Intervalley Coherent State in Rhombohedral Trilayer Graphene
Chun Wang Chau, Shuai A. Chen, K. T. Law
Superconductivity is observed in rhombohedral trilayer graphene in a narrow regime between the flavor-symmetric state and the symmetry breaking phase, which cannot be described by…
Flat Band Josephson Junctions with Quantum Metric
Zhong C. F. Li, Yuxuan Deng, Shuai A. Chen +2
In this work, we consider superconductor/flat band material/superconductor (S/FB/S) Josephson junctions (JJs) where the flat band material possesses isolated flat bands with exactl…
Geometric and conventional contributions of superconducting diode effect: Application to flat-band systems
Jin-Xin Hu, Shuai A. Chen, K. T. Law
Nonreciprocal critical supercurrents give rise to the superconducting diode effect (SDE) in noncentrosymmetric superconductors when time-reversal symmetry is broken. In this paper,…
