Phase structure and phase transitions of the SU(2) x O(N) symmetric scalar field theory
A. Patkos, Zs. Szep
Radiatively induced SU(2) symmetry breaking is shown to be a genuine feature of SU(2) x O(N) globally symmetric renormalisable field theories in the large N limit, describing inter…
Theory of a resonant level coupled to several conduction electron channels in equilibrium and out-of-equilibrium
Laszlo Borda, Karoly Vladar, Alfred Zawadowski
The spinless resonant level model is studied when it is coupled by hopping to one of the arbitrary number of conduction electron channels. The Coulomb interaction acts between the…
The critical surface of the SU(3)_L x SU(3)_R chiral quark model at non-zero baryon density
P. Kovacs, Zs. Szep
The boundary of the first order chiral phase transition region is studied in the m_pi-m_K-mu_B space using the one-loop optimized perturbation theory for the resummation of the per…
Einstein's fluctuation formula. A historical overview
Sandor Varro
A historical overview is given on the basic results which appeared by the year 1926 concerning Einstein's fluctuation formula of black-body radiation, in the context of light-quant…
A study on black-body radiation: classical and binary photons
Sandor Varro
The present study gives a detailed analysis of the black-body radiation based on classical random variables. It is shown that the energy of a mode of a chaotic radiation field (Gau…
Collective excitations and instability of an optical lattice due to unbalanced pumping
J. K. Asboth, H. Ritsch, P. Domokos
We solve self-consistently the coupled equations of motion for trapped particles and the field of a one-dimensional optical lattice. Optomechanical coupling creates long-range inte…
