Nambu-Jona Lasinio and Nonlinear Sigma Models in Condensed Matter Systems
Ryosuke Yoshii, Muneto Nitta
We review various connections between condensed matter systems with the Nambu-Jona Lasinio model and nonlinear sigma models. The field theoretical description of interacting system…
Hidden charge-conjugation, parity, and time-reversal symmetries and massive Goldstone (Higgs) modes in superconductors
Shunji Tsuchiya, Daisuke Yamamoto, Ryosuke Yoshii +1
A massive Goldstone (MG) mode, often referred to as a Higgs amplitude mode, is a collective excitation that arises in a system involving spontaneous breaking of a continuous symmet…
Spin imbalance effect on Larkin-Ovchinnikov-Fulde-Ferrel state
Ryosuke Yoshii, Shunji Tsuchiya, Giacomo Marmorini +1
We study spin imbalance effects on the Larkin-Ovchinikov-Fulde-Ferrel (LOFF) state relevant for superconductors under a strong magnetic field and spin polarized ultracold Fermi gas…
