Bound state of a hole and a triplet spin in the $t_1$-$t_2$-$J_1$-$J_2$ model
Bound state triplet spin
2010/11/17
We show that a hole and a triplet spin form a bound state in a nearly half-filled band of the one-and two-dimensional t1-t2-J1-J2 models. Numerical calculation indicates that the bound state is a spat...

We construct a bound state of three 1/3-quantized vortices in three-component su-perconductors with intrinsic Josephson couplings, which may be relevant with regard to iron-based superconductors. We f...
Waveguide QED: Many-Body Bound State Effects on Coherent and Fock State Scattering from a Two-Level System
Waveguide QED Many-Body Bound State Effects Coherent Fock State Scattering Two-Level System

Strong coupling between a two-level system (TLS) and bosonic modes produces dramatic quantum optics effects. We consider a one-dimensional continuum of bosons coupled to a single localized TLS, a syst...
