Emergence of magnetic excitations in one-dimensional quantum mixtures under confinement
Pablo Capuzzi, Patrizia Vignolo, Anna Minguzzi +1
We obtain an exact solution for the spectral function for one-dimensional Bose-Bose and Fermi- Fermi mixtures with strong repulsive interactions, valid in arbitrary confining poten…
Symmetry oscillations sensitivity to SU(2)-symmetry breaking in quantum mixtures
S. Musolino, M. Albert, P. Vignolo +1
In one-dimensional bosonic quantum mixtures with SU(2)-symmetry breaking Hamiltonian, the dynamical evolution explores different particle exchange symmetry sectors. For the case of…
Dynamical probing of high-order spin coherence in one-dimensional mixtures
Silvia Musolino, Gianni Aupetit-Diallo, Mathias Albert +2
We investigate the dynamics of one-dimensional SU(2) ultracold fermions near the Tonks-Girardeau limit, confined in a box potential. The system is driven out of equilibrium by init…
Cumulant theory of the unitary Bose gas: Prethermal and Efimovian dynamics
V. E. Colussi, H. Kurkjian, M. Van Regemortel +4
We study the quench of a degenerate ultracold Bose gas to the unitary regime, where interactions are as strong as allowed by quantum mechanics. We lay the foundations of a cumulant…
Dynamical formation of the unitary Bose gas
V. E. Colussi, S. Musolino, S. J. J. M. F. Kokkelmans
We study the structure of a Bose-condensed gas after quenching interactions to unitarity. Using the method of cumulants, we decompose the evolving gas in terms of clusters. Within…
