Multiorbital periodic Anderson model for CeRh2As2
Nico A. Hackner, Changhee Lee, P. M. R. Brydon
CeRh2As2 is a heavy-fermion superconductor that exhibits distinct low- and high-field superconducting phases, widely interpreted as reflecting a field-induced change in the parity…
Reentrant superconductivity enabled by spin-orbit coupling: Application to UTe
Changhee Lee, Nico A. Hackner, Daniel F. Agterberg +1
Reentrant superconductivity has been understood primarily in terms of the Jaccarino-Peter field-compensation effect or from a change of the strength in the pairing interaction. How…
Incommensuration in odd-parity antiferromagnets
Changhee Lee, Nico A. Hackner, P. M. R. Brydon
Inversion-asymmetric antiferromagnets (AFMs) with odd-parity spin-polarization pattern have been proposed as a new venue for spintronics. These AFMs require commensurate ordering t…
Solving the SU() Orbital Hatsugai-Kohmoto Model
Nico A. Hackner, Peizhi Mai, Philip W. Phillips
We show that the physics of the SU() Hubbard model can be realistically simulated with the recently developed orbital Hatsugai-Kohmoto model. In this approach, the momentum mixi…
Twisting the Hubbard model into the Momentum-Mixing Hatsugai-Kohmoto Model
Peizhi Mai, Jinchao Zhao, Gaurav Tenkila +4
The Hubbard model is a standard theoretical tool for studying materials with strong electron-electron interactions, such as the cuprate superconductors. Unfortunately, interaction-…
