Particle momentum spectra, correlations, and maximum entropy principle in high-multiplicity collision events
S. V. Akkelin
In this paper, we utilize the maximum entropy prescription to determine a quantum state of a small collision system at the kinetic freeze-out. We derive expressions for multiplicit…

Gradient corrections to the local-equilibrium energy-momentum tensor in the Zubarev approach
Sergii V. Akkelin, Dirk H. Rischke
We compute the expectation value of the energy-momentum tensor of a real scalar field in an approximation which accounts for spacetime gradients of the hydrodynamical variables in…
