Massive Schwinger model and its confining aspects on curved space-time
M. Alimohammadi, H. Mohseni Sadjadi
Using a covariant method to regularize the composite operators, we obtain the bosonized action of the massive Schwinger model on a classical curved background. Using the solution o…
On the phase structure of two--dimensional generalized Yang--Mills theories
M. Alimohammadi, M. Khorrami
The phase structure of the generalized Yang--Mills theories is studied, and it is shown that {\it almost} always, it is of the third order. As a specific example, it is shown that…
Observables of the generalized 2D Yang-Mills theories on arbitrary surfaces: a path integral approach
M. Khorrami, M. Alimohammadi
Using the path integral method, we calculate the partition function and the generating functional (of the field strengths) of the generalized 2D Yang-Mills theories in the Schwinge…
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…
Quantum group symmetry of the Quantum Hall effect on the non-flat surfaces
M. Alimohammadi, A. Shafei Deh Abad
After showing that the magnetic translation operators are not the symmetries of the QHE on non-flat surfaces , we show that there exist another set of operators which leads to the…
