Non-Hermitian Renormalization Group from a Few-Body Perspective
Hiroyuki Tajima, Masaya Nakagawa, Haozhao Liang +1
Non-Hermiticity plays a fundamental role in open quantum systems and describes a wide variety of effects of interactions with environments, including quantum measurement. However,…
Comparative study of quartet superfluid state: Quartet Bardeen-Cooper-Schrieffer theory and generalized Nambu-Gor'kov formalism
Yixin Guo, Hiroyuki Tajima, Haozhao Liang
We theoretically investigate a quartet superfluid state in fermionic matter by using the quartet Bardeen-Cooper-Schrieffer (BCS) variational theory and the Green's function method.…
Thermal liquid-gas phase transition in a quasi-one-dimensional dipolar Fermi gas
Lanxuan Gao, Koki Takayama, Hiroyuki Tajima +2
We theoretically investigate the thermodynamic properties of a quasi-one-dimensional single-component dipolar Fermi gas at finite temperatures. A self-bound fermionic droplet can b…
Emergent Fano-Feshbach resonance in two-band superconductors with an incipient quasi-flat band: Enhanced critical temperature evading particle-hole fluctuations
Hiroyuki Tajima, Hideo Aoki, Andrea Perali +1
In superconductivity, a surge of interests in enhancing is ever mounting, where a recent focus is toward multi-band superconductivity. In enhancements speci…
