Quasi-point versus point nodes in $S r_{2} R u O_{4}$ , the case of a flat tight binding $γ$ sheet

P. Contreras, Dianela Osorio, Shunji Tsuchiya

We perform a numerical study of the unitary regime as a function of disorder concentration in the imaginary part of the elastic scattering cross-section for the compound $Sr_2RuO_4…

Emergence of multiple Higgs modes due to spontaneous breakdown of a $Z_{2}$ symmetry in a superconductor

Shunji Tsuchiya

We study the Higgs mode in a Bardeen-Cooper-Schrieffer (BCS) superconductor. Motivated by the observation that U(1) symmetry of the BCS Hamiltonian is not essential for the Higgs m…
