Coleman-Weinberg mechanism in spinor Bose-Einstein condensates
Shun Uchino
It is argued that a continuous quantum phase transition between different ordered phases in spinor Bose-Einstein condensates predicted by the mean-field theory is vulnerable to qua…
Quantum Exact Non-Abelian Vortices in Non-relativistic Theories
Muneto Nitta, Shun Uchino, Walter Vinci
Non-Abelian vortices arise when a non-Abelian global symmetry is exact in the ground state but spontaneously broken in the vicinity of their cores. In this case, there appear (non-…
Competition of spin and charge excitations in the Hubbard model
Bruno Sciolla, Akiyuki Tokuno, Shun Uchino +3
Motivated by recent experiments with ultracold fermionic atoms in optical lattices, we study finite temperature magnetic correlations, as singlet and triplet correlations, and the…
Unconventional superfluidity in quasi-one-dimensional systems
Shun Uchino, Akiyuki Tokuno, Thierry Giamarchi
We show that an unconventional superfluid triggered by spin-orbit coupling is realized for repulsively interacting quasi-one-dimensional fermions. A competition between spin-single…
