Topological Landau Theory
Canon Sun, Joseph Maciejko
We present an extension of Landau's theory of phase transitions by incorporating the topology of the order parameter. When the order parameter comprises several components arising…
Hyperbolic Spin Liquids
Patrick M. Lenggenhager, Santanu Dey, Tomáš Bzdušek +1
Hyperbolic lattices present a unique opportunity to venture beyond the conventional paradigm of crystalline many-body physics and explore correlated phenomena in negatively curved…
Topological linear response of hyperbolic Chern insulators
Canon Sun, Anffany Chen, Tomáš Bzdušek +1
We establish a connection between the electromagnetic Hall response and band topological invariants in hyperbolic Chern insulators by deriving a hyperbolic analog of the Thouless-K…
