Isostaticity, auxetic response, surface modes, and conformal invariance in twisted kagome lattices
Kai Sun, Anton Souslov, Xiaoming Mao +1
Model lattices consisting of balls connected by central-force springs provide much of our understanding of mechanical response and phonon structure of real materials. Their stabili…
A theory of Topological Kondo Insulators
Maxim Dzero, Kai Sun, Piers Coleman +1
We examine how the properties of the Kondo insulators change when the symmetry of the underlying crystal field multiplets is taken into account. We employ the Anderson lattice mode…
Topological Phase Transitions for Interacting Finite Systems
Christopher N. Varney, Kai Sun, Marcos Rigol +1
In this paper, we investigate signatures of topological phase transitions in interacting systems. We show that the key signature is the existence of a topologically protected level…
Fractional quantum Hall effect in the absence of Landau levels
D. N. Sheng, Zheng-Cheng Gu, Kai Sun +1
It has been well-known that topological phenomena with fractional excitations, i.e., the fractional quantum Hall effect (FQHE) \cite{Tsui1982} will emerge when electrons move in La…
