On finite-temperature Fredholm determinants
Oleksandr Gamayun, Yuri Zhuravlev
We consider finite-temperature deformation of the sine kernel Fredholm determinants acting on the closed contours. These types of expressions usually appear as static two-point cor…
Non-reciprocal breathing solitons
Jonas Veenstra, Oleksandr Gamayun, Martin Brandenbourger +4
Breathing solitons consist of a fast beating wave within a compact envelope of stable shape and velocity. They can propagate and carry information and energy in a variety of contex…
Full-counting statistics for the alternating and domain-wall states
Oleksandr Gamayun
For a one-dimensional system of free fermions, we derive a connection between the full counting statistics of domain-wall and alternating occupancy (Néel) states. This allows us to…
One-dimensional Fermi polaron after a kick: two-sided singularity of the momentum distribution, Bragg reflection and other exact results
Oleksandr Gamayun, Oleg Lychkovskiy
A mobile impurity particle immersed in a quantum fluid forms a polaron - a quasiparticle consisting of the impurity and a local disturbance of the fluid around it. We ask what happ…
