Quantum Corrections to the Two Dimensional Gravity with External Field
We introduce an external field to calculate the quantum corrections to the solutions of the 2d gravity, via trace anomaly. We show that there are black hole type solutions even in the absence of matter field and cosmological constant. We also see that these solutions are similar to the ones obtained from dilaton two dimensional gravity. PACS: 04.60.+n; 11.17.+y; 97.60.Lf e-mail: [email protected]...
متن کاملTwo-Dimensional Seven-State Potts Model Under External Magnetic Field
The two-dimensional Potts Model with seven states under external field is studied using a cluster algorithm. Cluster size distribution and the fluctuations in the average cluster size provide helpful information on the order of phase transitions. Potts model [1] is known to have a very rich critical behaviour and considered as a testing ground for both analytical and numerical methods. Recently...
متن کاملControl of a two-electron quantum ring with an external magnetic field
We investigate the use of external time-dependent magnetic field for the control of the quantum states in a two-electron quantum ring. The hyperfine interaction of the confined electrons with surrounding nuclei couples the singlet state with the three triplet states. When the external magnetic field is changed, the singlet ground state becomes degenerate with the triplet states allowing singlet...
متن کاملTwo-loop QED with External Magnetic Field
In two loop effective Lagrangian, the low temperature expansion of the QED3+1 with a constant magnetic field and a finite chemical potential is performed. We then calculate the total fermion density, some components of polarization operator and de Hass -van Alphen oscillations. We find that there is a significant contribution from two-loop expansion to magnetization and fermion density for high...
