Theory of Laser-Controlled Competing Superconducting and Charge Orders
Michael A. Sentef, Akiyuki Tokuno, Antoine Georges +1
We investigate the nonequilibrium dynamics of competing coexisting superconducting (SC) and charge-density wave (CDW) orders in an attractive Hubbard model. A time-periodic laser f…
Detection of topological states in two-dimensional Dirac systems by the dynamic spin susceptibility
Masaaki Nakamura, Akiyuki Tokuno
We discuss dynamic spin susceptibility (DSS) in two-dimensional (2D) Dirac electrons with spin-orbit interactions to characterize topological insulators. The imaginary part of the…
Population-imbalance instability in a Bose-Hubbard ladder in the presence of a magnetic flux
Shun Uchino, Akiyuki Tokuno
We consider a two-leg Bose-Hubbard ladder in the presence of a magnetic flux. We make use of Gross-Pitaevskii, Bogoliubov, bosonization, and renormalization group approaches to rev…
Ground States of a Bose-Hubbard Ladder in an Artificial Magnetic Field: Field-Theoretical Approach
Akiyuki Tokuno, Antoine Georges
We consider a Bose-Hubbard ladder subject to an artificial magnetic flux and discuss its different ground states, their physical properties, and the quantum phase transitions betwe…
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…
