QCD-like Theories at Finite Baryon and Isospin Density
K. Splittorff, D. T. Son, M. A. Stephanov
We use 2-color QCD as a model to study the effects of simultaneous presence of chemical potentials for isospin charge, , and for baryon number, . We determine the phase d…
Domain walls of high-density QCD
D. T. Son, M. A. Stephanov, A. R. Zhitnitsky
We show that in very dense quark matter there must exist metastable domain walls where the axial U(1) phase of the color-superconducting condensate changes by 2pi. The decay rate o…
QCD at finite isospin density: from pion to quark-antiquark condensation
D. T. Son, M. A. Stephanov
QCD at finite isospin chemical potential mu_I is studied. This theory has no fermion sign problem and can be simulated on the lattice using present-day techniques. We solve this th…
Kinetic equation with exact charge conservation
C. M. Ko, V. Koch, Zi-wei Lin +3
We formulate the kinetic master equation describing the production of charged particles which are created or destroyed only in pairs due to the conservation of their Abelian charge…
When can long-range charge fluctuations serve as a QGP signal?
E. V. Shuryak, M. A. Stephanov
We critically discuss recent suggestion to use long-range modes of charge (electric or baryon) fluctuations as a signal for the presence of Quark-Gluon Plasma at the early stages o…
QCD at finite isospin density
D. T. Son, M. A. Stephanov
QCD at finite isospin chemical potential mu_I has no fermion sign problem and can be studied on the lattice. We solve this theory analytically in two limits: at low mu_I where chir…
