We simulate lattice QCD at a finite chemical potential ~1 for isospin (1s) at zero and finite temperatures. At some ~1 = pc QCD has a second order transition with mean-field critical exponents to a state where ( 13) is broken spontaneously by a charged pion condensate. Heating the system with PI > /

โฆ Synopsis
A connection between the operator fermionic currents J^ and corresponding 'Grassmannian' currents J in the functional integral formalism is studied. The QCD action with non-zero chemical potential p is derived. A connection between the fermionic Fock space and boundary conditions along the forth direction is discussed.

We present a quantitative analysis of the microscopic Dirac spectrum which is complex in the presence of a nonvanishing quark chemical potential. Data from quenched SU(3) lattice simulations for different volumes V and small values of the chemical potential p are compared to analytical predictions
This paper is concerned with a boundary-value problem, describing the stationary flow of a viscous, incompressible, electrically conducting fluid, confined to a bounded region of space, under mixed boundary conditions. The flow is governed by the Navier-Stokes equations, Ohm's law, and the Biot-Sava
