Fluid dynamics from the Boltzmann equation using a maximum entropy distribution
Chandrodoy Chattopadhyay, Ulrich Heinz, Thomas Schaefer
Using the recently developed ``Maximum Entropy'' (or ``least biased'') distribution function to truncate the moment hierarchy arising from kinetic theory, we formulate a far-from-e…
N-particle irreducible actions for stochastic fluids
Jingyi Chao, Thomas Schaefer
We construct one- and two-particle irreducible (1PI and 2PI) effective actions for the stochastic fluid dynamics of a conserved density undergoing diffusive motion. We compute the…
Far-off-equilibrium expansion trajectories in the QCD phase diagram
Chandrodoy Chattopadhyay, Ulrich Heinz, Thomas Schaefer
We consider the hydrodynamic evolution of a quark-gluon gas with non-zero quark masses and net baryon number in its phase diagram. For far-off-equilibrium initial conditions the ex…
Fluid Dynamics and Viscosity in Strongly Correlated Fluids
Thomas Schaefer
We review the modern view of fluid dynamics as an effective low energy, long wavelength theory of many body systems at finite temperature. We introduce the concept of a nearly perf…
Bulk viscosity, particle spectra and flow in heavy-ion collisions
Kevin Dusling, Thomas Schaefer
We study the effects of bulk viscosity on pT spectra and elliptic flow in heavy ion collisions. For this purpose we compute the dissipative correction df to the single particle dis…
Thermal conductivity of color-flavor locked quark matter
Matt Braby, Jingyi Chao, Thomas Schaefer
We compute the thermal conductivity of color-flavor locked (CFL) quark matter. At temperatures below the scale set by the gap in the quark spectrum, transport properties are determ…
Nearly Perfect Fluidity: From Cold Atomic Gases to Hot Quark Gluon Plasmas
Thomas Schaefer, Derek Teaney
Shear viscosity is a measure of the amount of dissipation in a simple fluid. In kinetic theory shear viscosity is related to the rate of momentum transport by quasi-particles, and…
Instantons and the large N_c limit, A.D. 2004
Thomas Schaefer
We review our current understanding of instanton effects in the large N_c limit of QCD. We argue that the instanton liquid can have a smooth large N_c limit which is in agreement w…
Effective Theory of Superfluid Quark Matter
Thomas Schaefer
We provide a brief introduction to the high density effective theory of QCD. As an application, we consider the instanton correction to the perturbatively generated gap in the colo…
Instanton Effects in QCD at High Baryon Density
Thomas Schaefer
We study instanton effects in QCD at very high baryon density. In this regime instantons are suppressed by a large power of , where is the QCD scale paramete…
Implications of the ALEPH tau-Lepton Decay Data for Perturbative and Non-Perturbative QCD
Thomas Schaefer, Edward Shuryak
We use ALEPH data on hadronic decays in order to calculate Euclidean coordinate space correlation functions in the vector and axial-vector channels. The linear combination $V-A…
Quark Hadron Continuity in QCD with one Flavor
Thomas Schaefer
We study QCD with one flavor at finite baryon density. In the limit of very high baryon density the system is expected to be a color superconductor. In the case of one flavor, the…
Gluino Condensation in an Interacting Instanton Ensemble
Thomas Schaefer
We perform a semi-classical study of chiral symmetry breaking and of the spectrum of the Dirac operator in QCD with adjoint fermions. For this purpose we calculate matrix elements…
Patterns of Symmetry Breaking in QCD at High Baryon Density
Thomas Schaefer
We study the structure of QCD at very large baryon density for an arbitrary number of flavors . We provide evidence that for any number of flavors larger than chiral s…
Superconductivity from perturbative one-gluon exchange in high density quark matter
Thomas Schaefer, Frank Wilczek
We study color superconductivity in QCD at asymptotically large chemical potential. In this limit, pairing is dominated by perturbative one-gluon exchange. We derive the Eliashberg…
High Density QCD and Instantons
R. Rapp, T. Schaefer, E. V. Shuryak +1
Instantons generate strong non-perturbative interactions between quarks. In the vacuum, these interactions lead to chiral symmetry breaking and generate constituent quark masses on…
Quark Description of Hadronic Phases
Thomas Schaefer, Frank Wilczek
We extend our proposal that major universality classes of hadronic matter can be understood, and in favorable cases calculated, directly in the microscopic quark variables, to allo…
Continuity of Quark and Hadron Matter
Thomas Schaefer, Frank Wilczek
We review, clarify, and extend the notion of color-flavor locking. We present evidence that for three degenerate flavors the qualitative features of the color-flavor locked state,…
High Density Quark Matter and the Renormalization Group in QCD with two and three flavors
Thomas Schaefer, Frank Wilczek
We consider the most general four fermion operators in QCD for two and three massless flavors and study their renormalization in the vicinity of the Fermi surface. We show that, as…
Diquark Bose Condensates in High Density Matter and Instantons
R. Rapp, T. Schaefer, E. V. Shuryak +1
Instantons lead to strong correlations between up and down quarks with spin zero and anti-symmetric color wave functions. In cold and dense matter, and $T…
Instantons and the Chiral Phase Transition at non-zero Baryon Density
Thomas Schaefer
We study an interacting ensemble of instantons at finite baryon chemical potential. We emphasize the importance of fermionic zero modes and calculate the fermion induced interactio…
Instantons in QCD
T. Schaefer, E. Shuryak
We review the theory and phenomenology of instantons in QCD. After a general overview, we provide a pedagogical introduction to semi-classical methods in quantum mechanics and fiel…
The axial anomaly in QCD at finite temperature
Thomas Schaefer
We study flavor mixing and the axial anomaly in QCD at zero and finite temperature. Using the instanton liquid model, we show that the strength of the anomaly is essentially unchan…
Hadronic Correlation Functions in the Interacting Instanton Liquid
T. Schaefer, E. V. Shuryak
We study hadronic correlation functions in the interacting instanton liquid model, both at zero and nonzero temperature . At zero we investigate the dependence of the correl…
