The equation of state in two-, three-, and four-color QCD at non-zero temperature and density
Tyler Gorda, Paul Romatschke
We calculate the equation of state at non-zero temperature and density from first principles in two-, three- and four-color QCD with two fermion flavors in the fundamental and two-…
Simulation of Black Hole Collisions in Asymptotically AdS Spacetimes
Hans Bantilan, Paul Romatschke
We present results from the evolution of spacetimes that describe the merger of asymptotically global AdS black holes in 5D with an SO(3) symmetry. Prompt scalar field collapse pro…
Particle spectra and HBT radii for simulated central nuclear collisions of C+C, Al+Al, Cu+Cu, Au+Au, and Pb+Pb from Sqrt(s)=62.4-2760 GeV
M. Habich, J. L. Nagle, P. Romatschke
We study the temperature profile, pion spectra and HBT radii in central symmetric and boost-invariant nuclear collisions using a super hybrid model for heavy-ion collisions (SONIC)…
Extracting the shear viscosity of a high temperature hadron gas
Paul Romatschke, Scott Pratt
Quark-Gluon plasmas produced in relativistic heavy-ion collisions quickly expand and cool, entering a phase consisting of multiple interacting hadronic resonances just below the QC…
Absence of a local rest frame in far from equilibrium quantum matter
Peter Arnold, Paul Romatschke, Wilke van der Schee
In a collision of strongly coupled quantum matter we find that the dynamics of the collision produces regions where a local rest frame cannot be defined because the energy-momentum…
Precision studies of v_n fluctuations
Tyler Gorda, Paul Romatschke
The power spectrum of heavy ion collisions is investigated by studying initial state fluctuations on top of a smooth hydrodynamic flow. In particular, the stability of the location…
