Electromagnetic Scattering in Degenerate and Partially Degenerate Nuclear Matter
Stephan Stetina
I calculate the rate of electromagnetic scattering in degenerate and partially degenerate plasmas composed of electrons, muons, protons, and neutrons. Correlations with strong inte…
The Photon in Dense Nuclear Matter I: Random Phase Approximation
Stephan Stetina, Ermal Rrapaj, Sanjay Reddy
We present a comprehensive and pedagogic discussion of the properties of photons in cold and dense nuclear matter based on the resummed one-loop photon self energy. Correlations be…
OSEFT or how to go beyond hard thermal loops
Cristina Manuel, Joan Soto, Stephan Stetina
We show that effective field theory techniques can be applied in the high temperature regime of plasmas to improve the accuracy of the physics of the hard scales (or scales of…
The on-shell effective field theory: a systematic tool to compute power corrections to the hard thermal loops
Cristina Manuel, Joan Soto, Stephan Stetina
We show that effective field theory techniques can be efficiently used to compute power corrections to the hard thermal loops (HTL) in a high temperature T expansion. To this aim,…
Instabilities in relativistic two-component (super)fluids
Alexander Haber, Andreas Schmitt, Stephan Stetina
We study two-fluid systems with nonzero fluid velocities and compute their sound modes, which indicate various instabilities. For the case of two zero-temperature superfluids we em…
From Field Theory to the Hydrodynamics of Relativistic Superfluids
Stephan Stetina
The hydrodynamic description of a superfluid is usually based on a two-fluid picture. In this thesis, basic properties of such a relativistic two-fluid system are derived from the…
Role reversal in first and second sound in a relativistic superfluid
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
Relativistic superfluidity at arbitrary temperature, chemical potential and (uniform) superflow is discussed within a self-consistent field-theoretical approach. Our starting point…
From field theory to superfluid hydrodynamics of dense quark matter
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
Hydrodynamics of superfluids can be described by formally dividing the fluid into a normal fluid and a superfluid part. In color-flavor locked quark matter, at least one superfluid…
Relativistic superfluid hydrodynamics from field theory
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
It is well known that the hydrodynamics of a zero-temperature superfluid can be formulated in field-theoretic terms, relating for example the superfluid four-velocity to the gradie…
From a complex scalar field to the two-fluid picture of superfluidity
Mark G. Alford, S. Kumar Mallavarapu, Andreas Schmitt +1
The hydrodynamic description of a superfluid is usually based on a two-fluid picture. We compute the basic properties of the relativistic two-fluid system from the underlying micro…
Ginzburg-Landau phase diagram for dense matter with axial anomaly, strange quark mass, and meson condensation
Andreas Schmitt, Stephan Stetina, Motoi Tachibana
We discuss the phase structure of dense matter, in particular the nature of the transition between hadronic and quark matter. Calculations within a Ginzburg-Landau approach show th…
