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…
Thermodynamics of rotating fermions
Victor E. Ambrus, Aleksandar GeciÄ
We consider the thermodynamic properties of a rotating gas of fermions. We begin by constructing the thermodynamic potential and its associated current within the gran…
Dirac fermions under imaginary rotation
Tudor PÄtuleanu, Amalia Dariana Fodor, Victor E. Ambrus +1
In the present study, we investigate the properties of an ensemble of free Dirac fermions, at finite inverse temperature and finite chemical potential , undergoing rigid r…
Acceleration as a circular motion along an imaginary circle: Kubo-Martin-Schwinger condition for accelerating field theories in imaginary-time formalism
Victor E. AmbruÅ, Maxim N. Chernodub
We discuss the imaginary-time formalism for field theories in thermal equilibrium in uniformly accelerating frames. We show that under a Wick rotation of Minkowski spacetime, the R…
Vortical waves in a quantum fluid with vector, axial and helical charges. II. Dissipative effects
Sergio Morales-Tejera, Victor E. AmbruÅ, Maxim N. Chernodub
In this paper, we consider the effect of interactions on the local, average polarization of a quantum plasma of massless fermion particles characterized by vector, axial, and helic…
Vortical waves in a quantum fluid with vector, axial, and helical charges. I. Non-dissipative transport
Sergio Morales-Tejera, Victor E. AmbruÅ, Maxim N. Chernodub
Due to the spin-orbit coupling, Dirac fermions, submerged in a thermal bath with finite macroscopic vorticity, exhibit a spin polarisation along the direction parallel to the vorti…
