Quench between a Mott insulator and a Lieb-Liniger liquid
G. Goldstein, N. Andrei
In this work we study a quench between a Mott insulator and a repulsive Lieb-Liniger liquid. We find explicitly the stationary state when a long time has passed after the quench. I…
Electrically Controlled Pumping of Spin Currents in Topological Insulators
R. Citro, F. Romeo, N. Andrei
Pure spin currents are shown to be generated by an electrically controlled quantum pump applied at the edges of a topological insulator. The electric rather than the more conventio…
Magnetism and superconductivity in underscreened Kondo chains
N. Andrei, E. Orignac
We present a one dimensional model of electrons coupled to localized moments of spin in which magnetism and superconductivity interplay in a nontrivial manner. This model…
Low-energy behavior of the spin-tube and spin-orbital models
E. Orignac, R. Citro, N. Andrei
The low-energy effective Hamiltonian of three coupled spin chains with periodic boundary conditions (spin tube) is expressed, in the limit of strong interchain coupling, in terms o…
Co-operative Kondo Effect in the two-channel Kondo Lattice
P. Coleman, A. M. Tsvelik, N. Andrei +1
We discuss the possibility of a co-operative Kondo effect driven by channel interference in a Kondo lattice where local moments are coupled to a single Fermi sea via two orthogonal…
Low temperature transport in the XXZ model
B. N. Narozhny, A. J. Millis, N. Andrei
We present evidence suggesting that spin transport in the gapless phase of the S=1/2 XXZ model is ballistic rather than diffusive. We map the model onto a spinless fermion model wh…
