The gauge theory dual of the bilayer XY model with second order Josephson coupling
Pye Ton How, Sungkit Yip
We formulate a duality transformation for a bilayer XY model where the layers are coupled by second order Josephson effect, which favors inter-layer phase difference of either …
Broken time reversal symmetry vestigial state for a two-component superconductor in two spatial dimensions
P. T. How, S. K. Yip
We consider the vestigial phase with broken time-reversal symmetry above the superconducting transition temperature of a two-component superconductor in two spatial dimensions. We…
The absence of Ginzburg-Landau mechanism for vestigial order in the normal phase above a two-component superconductor
Pye Ton How, Sung Kit Yip
A two-component superconductor may hypothetically support a vestigial order phase above its superconducting transition temperature, with rotational or time-reversal symmetry sponta…
Criterion for Vestigial Order above a Nematic Superconductor
P. T. How, S. K. Yip
A nematic superconductor can in principle support a vestigial order phase above its superconducting transition temperature, with rotational symmetry spontaneously broken while rema…
Shear Modulus Anomaly of Unconventional Superconductor in a Symmetry Breaking Field
Pye Ton How, Sung-Kit Yip
Using Ginzburg-Landau formalism, we theoretically study the isothermal shear modulus anomaly of an unconventional superconductor with a multicomponent order parameter, when the sup…
Half Quantum Vortices in Nematic Superconductor
Pye Ton How, Sung-Kit Yip
Motivated by the superconductivity of BiSe, we study topological excitations in a nematic superconductor using Ginzburg-Landau theory. An isolated excitation at low fi…
Signatures of Nematic Superconductivity in Doped BiSe under Applied Stress
Pye Ton How, Sung-Kit Yip
The family are candidates for topological superconductors, where could be Cu, Sr, or Nb. Two-fold anisotropy has been observed in various experime…
