Mobile impurity in a one-dimensional quantum gas: Exact diagonalization in the Bethe Ansatz basis
Evgeni Burovski, Oleksandr Gamayun, Oleg Lychkovskiy
We consider a mobile impurity particle injected into a one-dimensional quantum gas. The time evolution of the system strongly depends on whether the mass of the impurity and the ma…

Out-of-equilibrium dynamics of the Kitaev model on the Bethe lattice via coupled Heisenberg equations
Oleksandr Gamayun, Oleg Lychkovskiy
The Kitaev model on the honeycomb lattice, while being integrable via the spin-fermion mapping, has generally resisted an analytical treatment of the far-from-equilibrium dynamics…
