Competing orders in one-dimensional half-filled multicomponent fermionic cold atoms: The Haldane-charge conjecture
H. Nonne, P. Lecheminant, S. Capponi +2
We investigate the nature of the Mott-insulating phases of half-filled 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of conformal field…
Haldane charge conjecture in one-dimensional multicomponent fermionic cold atoms
H. Nonne, P. Lecheminant, S. Capponi +2
A Haldane conjecture is revealed for spin-singlet charge modes in 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of a low-energy approach…
Spin 3/2 fermions with attractive interactions in a one-dimensional optical lattice: phase diagrams, entanglement entropy, and the effect of the trap
G. Roux, S. Capponi, P. Lecheminant +1
We study spin 3/2 fermionic cold atoms with attractive interactions confined in a one-dimensional optical lattice. Using numerical techniques, we determine the phase diagram for a…
Molecular superfluid phase in systems of one-dimensional multicomponent fermionic cold atoms
S. Capponi, G. Roux, P. Lecheminant +3
We study a simple model of N-component fermions with contact interactions which describes fermionic atoms with N=2F+1 hyperfine states loaded into a one-dimensional optical lattice…
Zeeman effect in superconducting two-leg ladders: irrational magnetization plateaus and exceeding the Pauli limit
G. Roux, S. R. White, S. Capponi +1
The effect of a parallel magnetic field on superconducting two-leg ladders is investigated numerically. The magnetization curve displays an irrational plateau at a magnetization eq…
Doped two-leg ladder with ring exchange
G. Roux, S. R. White, S. Capponi +2
The effect of a ring exchange on doped two-leg ladders is investigated combining exact diagonalization (ED) and density matrix renormalization group (DMRG) computations. We focus o…
