Affine Jacobians of Spectral Curves and Integrable Models
F. A. Smirnov, V. Zeitlin
We explicitly construct the algebraic model of affine Jacobian of a generic algebraic curve of high genus and use it to compute the Euler characteristic of the Jacobian and investi…
On quantization of affine Jacobi varieties of spectral curves
F. A. Smirnov, V. Zeitlin
A quantum integrable model related to is considered. A reduced model is introduced which allows interpretation in terms of quantized affine Jacobi variety. Close…
Collective Excitations in Thermal QED_{3+1}: Survival of the Fittest
I. V. Tyutin, Vadim Zeitlin
The spectrum of collective fermionic excitations in a finite temperature QED_{3+1} is studied in different regimes. It is shown that within the standard perturbation approach the o…
Comment on "Dynamical Chern-Simons term generation at finite density" and "Chern-Simons term at finite density"
Vadim Zeitlin
We comment on the calculation of the Chern-Simons coefficient in (2+1)-dimensional gauge theories at finite chemical potential made by A.N.Sissakian, O.Yu.Shevchenko and S.B.Solgan…
Effective Lagrangian of Thermal QED with External Magnetic Field and the Static Limit of the Polarization Operator
Vadim Zeitlin
A low-temperature expansion of QED one-loop effective Lagrangian valid for a wide range of parameters is presented in a form of finite sums of elementary functions. Starting from t…
