Collisional dynamics of polaronic clouds immersed in a Fermi sea
Hiroyuki Tajima, Junichi Takahashi, Eiji Nakano +1
We propose a new protocol to examine many-polaron properties in a cold atom experiment. Initially, polaronic clouds are prepared around the opposite edges of a majority gas cloud.…
Spin-dipole mode in a trapped Fermi gas near unitarity
Hiroyuki Tajima, Alessio Recati, Yoji Ohashi
We theoretically investigate the spin-dipole oscillation of a strongly interacting Fermi gas in a harmonic trap. By using a combined diagrammatic strong-coupling theory with a loca…
Coexistence of giant Cooper pairs with a bosonic condensate and anomalous behavior of energy gaps in the BCS-BEC crossover of a two-band superfluid Fermi gas
Yuriy Yerin, Hiroyuki Tajima, Pierbiagio Pieri +1
We investigate Bardeen-Cooper-Schrieffer (BCS)- Bose-Einstein condensation (BEC) crossover in a two-band superfluid Fermi gas with an energy shift between the bands. When the intra…
Superfluid Phase Transitions and Effects of Thermal Pairing Fluctuations in Asymmetric Nuclear Matter
Hiroyuki Tajima, Tetsuo Hatsuda, Pieter van Wyk +1
We investigate superfluid phase transitions of asymmetric nuclear matter at finite temperature () and density () with a low proton fraction () which is rel…
QCD-like phase diagram with Efimov trimers and Cooper pairs in resonantly interacting SU(3) Fermi gases
Hiroyuki Tajima, Pascal Naidon
We investigate color superfluidity and trimer formation in resonantly interacting SU(3) Fermi gases with a finite interaction range. The finite range is crucial to avoid the Thomas…
Generalized Crossover in Interacting Fermions within the Low-Energy Expansion
Hiroyuki Tajima
We generalize the Bardeen-Cooper-Schrieffer-Bose-Einstein-condensation (BCS-BEC) crossover of two-component fermions, which is realized by tuning the -wave scattering length …
