Effect of magnetic field on spontaneous Fermi surface symmetry breaking
Hiroyuki Yamase
We study magnetic field effects on spontaneous Fermi surface symmetry breaking with d-wave symmetry, the so-called d-wave "Pomeranchuk instability''. We use a mean-field model of e…
Competition of Fermi surface symmetry breaking and superconductivity
Hiroyuki Yamase, Walter Metzner
We analyze a mean-field model of electrons on a square lattice with two types of interaction: forward scattering favoring a d-wave Pomeranchuk instability and a BCS pairing interac…
Van Hove singularity and spontaneous Fermi surface symmetry breaking in Sr3Ru2O7
Hiroyuki Yamase, Andrey A. Katanin
The most salient features observed around a metamagnetic transition in Sr3Ru2O7 are well captured in a simple model for spontaneous Fermi surface symmetry breaking under a magnetic…
Theory of the in-plane anisotropy of magnetic excitations in YBa_{2}Cu_{3}O_{6+y}
Hiroyuki Yamase, Walter Metzner
A pronounced xy-anisotropy was observed in recent neutron scattering experiments for magnetic excitations in untwinned YBa_{2}Cu_{3}O_{6+y} (YBCO). The small anisotropy of the bare…
