On Supersymmetry at Finite Temperature
We consider the effective theories governing the sensitivity to the plasma of certain high-energy observables in supersymmetric plasmas, and point out that they preserve supersymmetry. Our findings generalize previous observations on asymptotic thermal masses in weakly coupled plasmas, to both the real and imaginary parts of self-energies, on the light cone and away from it, in weakly and stron...
متن کاملOn Supersymmetry at High Temperature
While it is possible to find examples of field theories with a spontaneously broken symmetry at high temperature, in renormalizable supersymmetric models any internal symmetry gets always restored. Recently, a counterexample was suggested in the context of nonrenormalizable supersymmetric theories. We show that non negligible higher loop effects actually restore the symmetry, without compromisi...
متن کاملSupersymmetry and finite - temperature strings ∗
We describe finite temperature N = 4 superstrings in D = 5 by an effective fourdimensional supergravity of the thermal winding modes that can become tachyonic and trigger the instabilities at the Hagedorn temperature. Using a domain-wall ansatz, exact solutions to special BPS-type first order equations are found. They preserve half of the supersymmetries, contrary to the standard perturbative s...
متن کاملSupersymmetry and Electron-hole Excitations in Semiconductors at Finite Temperature
The fermionic and bosonic electron-hole low lying excitations in a semiconductor are analyzed at finite temperature in a unified way following Nambu’s quasi-supersymmetric approach for the BCS model of superconductivity. The effective lagrangian for the fermionic modes and for the bosonic low lying collective excitations in the semiconductor is no longer supersymmetric in a conventional finite ...
متن کاملGoldstone Realization of Lorentz-symmetry and Supersymmetry at Finite Temperature*
The Ward-Takahashi identities of Lorentz symmetry are examined at finite temperature. It is shown that the Lorentz symmetry is broken with the Goldstone realization. The analogy with finite-temperature supersymmetry-breaking in an R-invariant model is explained. Submitted to Physics Letters B * Work supported by the Department of Energy, contract DE AC03 76SF00515. The supersymmetry has been kn...
