Universal and non-universal tails of distribution functions in the directed polymer and KPZ problems
I. V. Kolokolov, S. E. Korshunov
The optimal fluctuation approach is applied to study the most distant (non-universal) tails of the free-energy distribution function P(F) for an elastic string (of a large but fini…
Joint free energy distribution in the random directed polymer problem
V. S. Dotsenko, L. B. Ioffe, V. B. Geshkenbein +2
We consider two configurations of a random directed polymer of length L confined to a plane and ending in two points separated by 2u. Defining the mean free energy and the…
Optimal fluctuation approach to a directed polymer in a random medium
I. V. Kolokolov, S. E. Korshunov
A modification of the optimal fluctuation approach is applied to study the tails of the free energy distribution function P(F) for an elastic string in quenched disorder both in th…
Comment on "Probing vortex unbinding via dipole fluctuations"
S. E. Korshunov
We demonstrate that the method suggested by Fertig and Straley [Phys. Rev. B 66, 201402 (2002)] for the identification of different phases in two-dimensional XY models does not all…
Nature of phase transition(s) in striped phase of triangular-lattice Ising antiferromagnet
S. E. Korshunov
Different scenarios of the fluctuation-induced disordering of the striped phase which is formed at low temperatures in the triangular-lattice Ising model with the antiferromagnetic…
Fluctuation induced vortex pattern and its disordering in the fully frustrated XY model on a dice lattice
S. E. Korshunov
A highly degenerate family of states [proposed in PRB 63, 134503 (2001)] is proven to really minimize the Hamiltonian of the fully frustrated XY model on a dice lattice. The harmon…
