Journal Article
Lan, Z., & Powell, S. (in press). Eigenstate thermalization hypothesis in quantum dimer models. Physical Review B, 96(11), https://doi.org/10.1103/PhysRevB.96.115140

We use exact diagonalization to study the eigenstate thermalization hypothesis (ETH) in the quantum dimer model on the square and triangular lattices. Due to the nonergodicity of the local plaquette-ip dynamics, the Hilbert space, which consists of h... Read More about Eigenstate thermalization hypothesis in quantum dimer models.

Mean-field theory for confinement transitions and magnetization plateaux in spin ice (2017)

We study phase transitions in classical spin ice at nonzero magnetization, by introducing a mean-field theory designed to capture the interplay between confinement and topological constraints. The method is applied to a model of spin ice in an applie... Read More about Mean-field theory for confinement transitions and magnetization plateaux in spin ice.
