Magnetic solitons in Rabi-coupled Bose-Einstein condensates
Chunlei Qu, Marek Tylutki, Sandro Stringari +1
We study magnetic solitons, solitary waves of spin polarization (i.e., magnetization), in binary Bose-Einstein condensates in the presence of Rabi coupling. We show that the system…
Expansion of harmonically trapped interacting particles and time dependence of the contact
Chunlei Qu, Lev P. Pitaevskii, Sandro Stringari
We study the expansion of an interacting atomic system at zero temperature, following its release from an isotropic three-dimensional harmonic trap and calculate the time dependenc…
Valley-Selective Topological Ordered States in Irradiated Bilayer Graphene
Chunlei Qu, Chuanwei Zhang, Fan Zhang
Gapless bilayer graphene is susceptible to a variety of spontaneously gapped states. As predicted by theory and observed by experiment, the ground state is however topologically tr…
Spin-Dipole Oscillation and Polarizability of a Binary Bose-Einstein Condensate near the Miscible-Immiscible Phase Transition
Tom Bienaimé, Eleonora Fava, Giacomo Colzi +6
We report on the measurement of the spin-dipole (SD) polarizability and of the frequency of the SD oscillation of a two-component Bose-Einstein condensate of sodium atoms occupying…
Optical-lattice-assisted magnetic phase transition in a spin-orbit-coupled Bose-Einstein condensate
Giovanni I. Martone, Tomoki Ozawa, Chunlei Qu +1
We investigate the effect of a periodic potential generated by a one-dimensional optical lattice on the magnetic properties of an spin-orbit-coupled Bose gas. By increasing…
Magnetic Solitons in a Binary Bose-Einstein Condensate
Chunlei Qu, Lev P. Pitaevskii, Sandro Stringari
We study solitary waves of polarization (magnetic solitons) in a two-component Bose gas with slightly unequal repulsive intra- and interspin interactions. In experimentally relevan…
