Moment of Inertia of an Interacting Bose Gas
Aleksandar Gecic, Victor E. Ambrus, Kenji Fukushima
The response of many-body quantum systems to rotation can be characterized by the moment of inertia. For a classical gas, the moment of inertia can be expressed as the integral of…
Numerical Simulation of Black Hole Images from photon trajectories in Schwarzschild Geometry
Alin Galea, Victor E. Ambrus
With the arrival of advanced telescopes such as the Event Horizon Telescope (EHT), direct imaging of a black hole's shadow became a reality. Simulations play an important role in r…
Extended applicability domain of viscous anisotropic hydrodynamics in (2+1)-D Bjorken flow with transverse expansion
Yiyang Peng, Victor E. Ambrus, Clemens Werthmann +3
We perform (2+1)-D simulations of viscous anisotropic hydrodynamics (VAH) under boost-invariant and conformal conditions. Comparing both VAH and traditional viscous hydrodynamics w…
Linear sigma model with quarks and Polyakov loop in rotation: phase diagrams, Tolman-Ehrenfest law and mechanical properties
Pracheta Singha, Sergiu Busuioc, Victor E. Ambrus +1
We study the effect of rotation on the confining and chiral properties of QCD using the Polyakov-enhanced linear sigma model coupled to quarks. Working in the homogeneous approxima…
Signatures of local acceleration of quark-gluon plasma in the dilepton production
Aritra Bandyopadhyay, Moulindu Kundu, Victor E. Ambrus +1
Dilepton production is one of the key probes of the Quark-Gluon Plasma (QGP) that encodes the imaginary part of the electromagnetic current-current correlator. We investigate the e…
Vielbein Lattice Boltzmann approach for fluid flows on spherical surfaces
Victor E. Ambrus, Elisa Bellantoni, Sergiu Busuioc +2
In this paper, we develop a lattice Boltzmann scheme based on the Vielbein formalism for the study of fluid flows on spherical surfaces. The Vielbein vector field encodes all detai…
