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…
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…
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…
Quantum Monte Carlo estimation of complex-time correlations for the study of the ground-state dynamic structure function
Riccardo Rota, Joaquim Casulleras, Ferran Mazzanti +1
We present a method based on the Path Integral Monte Carlo formalism for the calculation of ground-state time correlation functions in quantum systems. The key point of the method…
Quantum Monte Carlo study of spin-polarized deuterium
I. Beslic, L. Vranjes Markic, J. Casulleras +1
The ground state properties of spin-polarized deuterium (D) at zero temperature are obtained by means of the diffusion Monte Carlo calculations within the fixed-node ap…
