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…
Large time and long distance asymptotics of the thermal correlators of the impenetrable anyonic lattice gas
Yuri Zhuravlev, Eduard Naichuk, Nikolai Iorgov +1
We study thermal correlation functions of the one-dimensional impenetrable lattice anyons. These correlation functions can be presented as a difference of two Fredholm determinants…
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…
On the Dynamics of Free-Fermionic Tau-Functions at Finite Temperature
Daniel Chernowitz, Oleksandr Gamayun
In this work we explore an instance of the -function of vertex type operators, specified in terms of a constant phase shift in a free-fermionic basis. From the physical point of…
