Thermo Field Dynamics for Quantum Fields with Continuous Mass Spectrum Applied to Nuclear Physics
Transport coefficients are obtained by incorporating a gauge principle into thermo field dynamics of inhomogeneous systems. In contrast to previous derivations, neither imaginary time arguments nor perturbation theory in powers of a coupling constant are used in the calculation. Numerical values are calculated for the pion component in hot nuclear matter.
متن کاملThermo Field Dynamics and quantum algebras
The algebraic structure of Thermo Field Dynamics lies in the q-deformation of the algebra of creation and annihilation operators. Doubling of the degrees of freedom, tilde-conjugation rules, and Bogoliubov transformation for bosons and fermions are recognized as algebraic properties of hq(1) and of hq(1|1), respectively.

متن کاملFe b 19 94 A Transport Equation for Quantum Fields with Continuous Mass Spectrum ∗
Within a relativistic real-time Green's function formalism, a quantum transport equation for the phase-space distribution function is derived without a quasi-particle approximation. Dissipation is due to a nonzero spectral width, and can be separated into time-local and memory effects.
متن کاملSupersymmetry in Thermo Field Dynamics
By considering the enlarged thermal system including the heat bath, it is shown that this system has supersymmetry which is not broken at finite temperature. The superalgebra is constructed and the Hamiltonian is expressed as the anti-commutator of two kinds of super charges. With this Hamiltonian and the thermal vaccum | 0(β) >, this supersymmetry is found to be preserved.
متن کاملA Second Supersymmetry in Thermo Field Dynamics
This article is an extension of the work done in [1] by R. Parthasarathy and R. Sridhar. There they consider supersymmetry in an enlarged thermal system (in a thermo field dynamic formulation) and show that this supersymmetry is not broken at finite temperature. Here we show, using an SU(1, 1) R-symmetry, that this system obeys a second supersymmetry. In addition, we proceed to see that this ne...
