One Loop Counterterms in 2D Dilaton-Maxwell Quantum Gravity
E. Elizalde, S. Naftulin, S. D. Odintsov
The renormalization structure of two-dimensional quantum gravity is investigated, in a covariant gauge. One-loop divergences of the effective action are calculated. All the surface…
A Finite-Temperature Periodic Structure in (SUPER)STRING Theory
A. A. Bytsenko, E. Elizalde, S. D. Odintsov +1
Using a Laurent series representation for the (super)string one-loop free energy, an explicit form for the analytic continuation of the Laurent series beyond the critical (Hagedorn…
Gravitational Phase Transitions in Infrared Quantum Gravity
E. Elizalde, S. D. Odintsov
The conformal anomaly induced sector of four-dimensional quantum gravity (infrared quantum gravity) ---which has been introduced by Antoniadis and Mottola--- is here studied on a c…
A Novel Representation for the Free Energy in String Theory at Non-Zero Temperature
A. A. Bytsenko, E. Elizalde, S. D. Odintsov +1
A novel representation ---in terms of a Laurent series--- for the free energy of string theory at non-zero temperature is constructed. The examples of open bosonic, open supersymme…
Laurent Series Representation for the Open Superstring Free Energy
A. A. Bytsenko, E. Elizalde, S. D. Odintsov nd S. Zerbini
Open superstrings at non-zero temperature are considered. A novel representation for the free energy (Laurent series representation) is constructed. It is shown that the Hagedorn t…
Schrodinger Equation for Particle with Friction
Alexios P. Polychronakos, Rodanthy Tzani
A new quantum mechanical wave equation describing a particle with frictional forces is derived. It depends on a parameter whose range is determined by the coefficient of fricti…
