Mass-imbalanced SU(N) Fermi gases
Jordi Pera, Joaquim Casulleras, Jordi Boronat
We report a fully analytical description of zero-temperature itinerant ferromagnetism in repulsive SU(N) Fermi gases with arbitrary mass imbalance among components. Using perturbat…
Equation of state of Bose gases beyond the universal regime
Marti Planasdemunt, Jordi Pera, Jordi Boronat
The equation of state of dilute Bose gases, in which the energy only depends on the -wave scattering length, is rather unknown beyond the universal limit. We have carried out a…
Interaction effects on the itinerant ferromagnetism phase transition
Jordi Pera, Joaquim Casulleras, Jordi Boronat
Itinerant ferromagnetism is one of the most studied quantum phase transitions, the transition point and the nature of this phase transition being widely discussed. In dilute Fermi…
Low-energy scattering parameters: A theoretical derivation of the effective range and scattering length for arbitrary angular momentum
Jordi Pera, Jordi Boronat
The most important parameters in the study of low-energy scattering are the s-wave and p-wave scattering lengths and the s-wave effective range. We solve the scattering problem and…
Beyond universality in repulsive SU(N) Fermi gases
Jordi Pera, Joaquim Casulleras, Jordi Boronat
Itinerant ferromagnetism in dilute Fermi gases is predicted to emerge at values of the gas parameter where second-order perturbation theory is not accurate enough to properly descr…
Itinerant ferromagnetism in dilute SU(N) Fermi gases
Jordi Pera, Joaquim Casulleras, Jordi Boronat
We present exact analytic results for the energy of a SU(N) repulsive Fermi gas as a function of the spin-channel occupation at second order in the gas parameter. This is an extens…
