The column vector calculus for Thermo Field Dynamics of relativistic quantum fields

A formalism is discussed which simplifies the calculation of Feynman diagrams at finite temperature.Comment: 10 pages, GSI-Preprint 93-32 (1993

Thermo Field Dynamics and Kinetic Coefficients of a Charged Boson Gas

Thermo Field Dynamics for inhomogeneous systems is generalized to quantum fields with a continuous single-particle mass spectrum. The modification of the hamiltonian in states with a local thermal Bogoliubov symmetry is used to calculate thermal conductivity and diffusion coefficient of pions interacting with hot, compressed nuclear matter.Comment: 27 pages in LaTeX GSI-Preprint 93-45 (1993

HBT with Space- vs. Time-like Hydrodynamic Freezeout

Bose-Einstein correlations in relativistic heavy ion collisions and their dependence on the freeze-out condition in hydrodynamic models is compared to time-like freeze-out, where particles are emitted away only from the surface, i.e. space- vs. time-like freeze-out. The corresponding HBT radii are calculated for the two models emphasizing the difference in the outward HBT radius.Comment: Proc. of hydrodynamics workshop, may 12-16, Trent
