The nonlinear Hall effect refers to the nonlinear voltage response that is transverse to the applied electric field. Recent studies have shown that the quantum geometric quantities on Fermi surfaces serve as fundamental contributors to the nonlinear

The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, a finite-momentum superconducting pairing state, has been extensively studied from the perspective of mismatched Fermi surfaces of paired electrons. In this work, we propose a distinctive mechanism t

In van der Waals heterostructures (vdWHs), the manipulation of interlayer stacking/coupling allows for the construction of customizable quantum systems exhibiting exotic physics. An illustrative example is the diverse range of states of matter achiev

We discuss the excitons in flat band systems. Quantum metric plays a central role in determining the properties of single exciton excitation as well as the exciton condensate. While the electrons and holes are extremely heavy in flat bands, the excit

The relation between band topology and Majorana zero energy modes (MZMs) in topological superconductors had been well studied in the past decades. However, the relation between the quantum metric and MZMs has yet to be understood. In this work, we fi

Superconductivity (SC) is observed in rhombohedral trilayer graphene (RTG) with an extremely low charge carrier densities, between the normal metal state and a probable inter-valley coherent (IVC) state. The measured coherence length in RTG is roughl

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 exactly zero Fermi velocity. Contrary to conventional S/N/S JJs where the cr

The nonreciprocal critical supercurrents endow the superconducting diode effect (SDE) in noncentrosymmetric superconductors with time-reversal symmetry breaking. Recently, it was reported that the SDE has been observed in narrow-band superconductors

Magnetic topological states refer to a class of exotic phases in magnetic materials with their non-trivial topological property determined by magnetic spin configurations. An example of such states is the quantum anomalous Hall (QAH) state, which is

Recently, gate-defined Josephson junctions based on magic-angle twisted bilayer graphene (MATBG) have been fabricated. In such a junction, local electrostatic gating can create two superconducting regions connected by an interaction-driven valley-pol
