General Unitary TFD Formulation for Superstrings
M. C. B. Abdalla, A. L. Gadelha, Daniel L. Nedel
A generalization of the Thermo Field Dynamics (TFD) for fermionic degrees of freedom is proposed. Such a generalization follows a previous one where the SU(1,1) thermal group was u…
Superspace Type II 4D Supergravity from Type II Superstring
Daniel L. Nedel
We derive the equations of motion of type II 4D supergravity in superspace. This is achieved by coupling the Type II Berkovits' hybrid superstring to an N=2 curved background and r…
Perspectives of TFD on String Theory
M. C. B. Abdalla, A. L. Gadelha, Daniel L. Nedel
Considering the type IIB superstring in a pp wave background some recent ideas and perspectives of Thermo Field Dynamics on string theory are presented. The thermal Fock space is c…
Closed String Thermal Torus From Thermo Field Dynamics
M. C. B Abdalla, A. L. Gadelha, Daniel L. Nedel
In this Letter a topological interpretation for the string thermal vacuum in the Thermo Field Dynamics (TFD) approach is given. As a consequence, the relationship between the Imagi…
On the entropy operator for the general SU(1,1) TFD formulation
M. C. Abdalla, A. L. Gadelha, Daniel L. Nedel
In this letter, an entropy operator for the general unitary SU(1,1) TFD formulation is proposed and used to lead a bosonic system from zero to finite temperature. Namely, consideri…
Superstring in a pp-wave background at finite temperature - TFD approach
Daniel L. Nedel, M. C. B. Abdalla, A. L. Gadelha
A thermodynamical analysis for the type IIB superstring in a pp-wave background is considered. The thermal Fock space is built and the temperature SUSY breaking appears naturally b…
