Magnetism in f electron superlattices
Robert Peters, Yasuhiro Tada, Norio Kawakami
We analyze antiferromagnetism in electron superlattices. We show that the competition between the Kondo effect and the RKKY interaction in electron materials is modified by…
Decay of Superconducting Correlations for Gauged Electrons in Dimensions
Yasuhiro Tada, Tohru Koma
We study lattice superconductors coupled to gauge fields, such as an attractive Hubbard model in electromagnetic fields, with a standard gauge fixing. We prove upper bounds for a t…
Magnetism and Superconductivity in Ferromagnetic Heavy Fermion System UCoGe under In-plane Magnetic Fields
Yasuhiro Tada, Shintaro Takayoshi, Satoshi Fujimoto
We study the ferromagnetic superconductor UCoGe at ambient pressure under -plane magnetic fields which are perpendicular to the ferromagnetic easy axis. It is shown t…
Two No-Go Theorems on Superconductivity
Yasuhiro Tada, Tohru Koma
We study lattice superconductors such as attractive Hubbard models. As is well known, Bloch's theorem asserts absence of persistent current in ground states and equilibrium states…
