[UNESP]2015-10-212015-10-212015-01-23Physical Review A, v. 91, n. 1, p. 1-10, 2015.1050-2947http://hdl.handle.net/11449/128967We study the ground-state density profile of a spin-orbit-coupled f = 2 spinor condensate in a quasi-one-dimensional trap. The Hamiltonian of the system is invariant under time reversal but not under parity. We identify different parity- and time-reversal symmetry-breaking states. The time-reversal symmetry breaking is possible for degenerate states. A phase separation among densities of different components is possible in the domain of time-reversal symmetry breaking. Different types of parity- and time-reversal symmetry-breaking states are predicted analytically and studied numerically. We employ numerical and approximate analytic solutions of a mean-field model in this investigation to illustrate our findings.1-10engArtigo10.1103/PhysRevA.91.013624WOS:000349421000006Acesso restrito8031087349809439
