Derivation of quantum theories:symmetries and the exact solution of the derived system
M. Khorrami, A. Aghamohammadi, M. Alimohammadi
Based on the technique of derivation of a theory, presented in our recent paper, we investigate the properties of the derived quantum system. We show that the derived quantum syste…
A pseudo-conformal representation of the Virasoro algebra
A. Aghamohammadi, A. Alimohammadi, M. Khorrami
Generalizing the concept of primary fields, we find a new representation of the Virasoro algebra, which we call it a pseudo-conformal representation. In special cases, this represe…
Toda theories as contraction of affine Toda theories
A. Aghamohammadi, M. Khorrami, A. Shariati
Using a contraction procedure, we obtain Toda theories and their structures, from affine Toda theories and their corresponding structures. By structures, we mean the equation of mo…
The Logarithmic Conformal Field Theories
M. R. Rahimi Tabar, A. Aghamohammadi, M. Khorrami
We study the correlation functions of logarithmic conformal field theories. First, assuming conformal invariance, we explicitly calculate two-- and three-- point functions. This ca…
Gauging of Lorentz Group WZW Model by its Null Subgroup
Amir Masoud Ghezelbash
We consider the standard vector gauging of Lorentz group WZW model by its non-semisimple null Euclidean subgroup in two dimensions . The resultant effective act…
Remarks on a Decrumpling Model of the Universe
J. A. S. Lima, M. Mohazzab
It is argued that when the dimension of space is a constant integer the full set of Einstein's field equations has more information than the spatial components of Einstein's equati…
