Strain-induced Berry phase in chiral superconductors
Canon Sun, Marcel Franz, Joseph Maciejko
We study the topology of the order parameter in the intermediate phase between the superconducting and time-reversal symmetry breaking transitions of a superconductor un…

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…

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…
