Superconductivity and bosonic fluid emerging from Moiré flat bands
Xu Zhang, Kai Sun, Heqiu Li +2
Although evidence of inter-valley attraction-mediated by phonon or topological fluctuations is accumulating, the origin of superconductivity in the flat-band quantum moiré material…
Massive Dirac fermions in moiré superlattices: a route towards topological flat minibands
Ying Su, Heqiu Li, Chuanwei Zhang +2
We demonstrate a generic mechanism to realize topological flat minibands by confining massive Dirac fermions in a periodic moiré potential, which can be achieved in a heterobilayer…
Classification of phase transitions and intertwined orders in crystallographic point groups
Heqiu Li
Symmetry provides important insight in understanding the nature of phase transitions. In the presence of crystalline symmetries, new phenomena in phase transition can emerge, such…
Dynamical properties of collective excitations in twisted bilayer Graphene
Gaopei Pan, Xu Zhang, Heqiu Li +2
Employing the recently developed momentum-space quantum Monte Carlo scheme, we study the dynamic response of single-particle and collective excitations in realistic continuum model…
Existence of Corner Modes in Elastic Twisted Kagome Lattices
Hrishikesh Danawe, Heqiu Li, Hasan Al Ba'ba'a +1
This Letter investigates the emergence of corner modes in elastic twisted Kagome lattices at a critical twist angle, known as self-dual point. We show that a special type of corner…
Spontaneous fractional Chern insulators in transition metal dichalcogenides Moire superlattices
Heqiu Li, Umesh Kumar, Kai Sun +1
Moir{é} superlattice realized in two-dimensional heterostructures offers an exciting platform to access strongly-correlated electronic states. In this work, we study transition met…
