Critical couplings of two dimensional Ising model on various lattices

Sh. Khachatryan, A. Sedrakyan

We develop a unified fermionic-field formulation of the two-dimensional Ising model on several planar lattices using the Kac-Ward representation. Grassmann fields are associated wi…

Explicit R-matrices for inhomogeneous 3D chiral Potts models: Integrability and the action formulation for

Sh. Khachatryan, A. Sedrakyan

We construct the exact spectral parameter dependent vertex R-matrix for the classical 3D -state chiral Potts models, convenient for considering the model in context of…

Geometry of random potentials: Induction of 2D gravity in Quantum Hall plateau transitions

Riccardo Conti, Hrant Topchyan, Roberto Tateo +1

In the context of the Integer Quantum Hall plateau transitions, we formulate a specific map from random landscape potentials onto 2D discrete random surfaces. Critical points of th…

Deformation of graphene sheet: Interaction of fermions with phonons

Ara Sedrakyan, Andreas Sinner, Klaus Ziegler

We construct an effective low energy Hamiltonian which describes fermions dwelling on a deformed honeycomb lattice with dislocations and disclinations, and with an arbitrary hoppin…

Critical behavior at the integer quantum Hall transition in a network model on the Kagome lattice

I. A. Gruzberg, N. Charles, A. Klümper +2

We study a network model on the Kagome lattice (NMKL). This model generalizes the Chalker-Coddington (CC) network model for the integer quantum Hall transition. Unlike random netwo…

Topological Indices of Proteins

Dmitry Melnikov, Antti J Niemi, Ara Sedrakyan

Protein molecules can be approximated by discrete polygonal chains of amino acids. Standard topological tools can be applied to the smoothening of the polygons to introduce a topol…
