Non-local order parameters for states with topological electromagnetic response
Thomas Klein Kvorning, Christian Spånslätt, AtMa P. O. Chan +1
Chern insulators are states of matter characterized by a quantized Hall conductance, gapless edge modes but also a singular response to monopole configurations of an external elect…
Braiding with Borromean Rings in (3+1)-Dimensional Spacetime
AtMa P. O. Chan, Peng Ye, Shinsei Ryu
While winding a particle-like excitation around a loop-like excitation yields the celebrated Aharonov-Bohm phase, we find a distinctive braiding phase in the absence of such mutual…
Effective hydrodynamic field theory and condensation picture of topological insulators
AtMa P. O. Chan, Thomas Kvorning, Shinsei Ryu +1
While many features of topological band insulators are commonly discussed at the level of single-particle electron wave functions, such as the gapless Dirac spectrum at their bound…
Topological Phases on Non-orientable Surfaces: Twisting by Parity Symmetry
AtMa P. O. Chan, Jeffrey C. Y. Teo, Shinsei Ryu
We discuss (2+1)D topological phases on non-orientable spatial surfaces, such as Möbius strip, real projective plane and Klein bottle, etc., which are obtained by twisting the pare…
