Interacting quantum walkers: two-body bosonic and fermionic bound states
Interacting quantum walkers: two-body bosonic and fermionic bound states
We investigate the dynamics of bound states of two interacting particles, either bosons or fermions, performing a continuous-time quantum walk on a one-dimensional lattice. We consider the situation where the distance between both particles has a hard bound, and the richer situation where the particles are bound by a smooth …
