Coulomb-Gas Approach For Percolation Theory
Smain Balaska, Toufik Sahabi
The aim of this work is to present a non trivial confirmation of the powerful of the Coulomb gas-techniques for Boundary Conformal Field Theory (BCFT). We show that we can re-deriv…
The Boundary Conformal Field Theories of the 2D Ising critical points
Smain Balaska, Nahed Sihem Bounoua
We present a new method to identify the Boundary Conformal Field Theories (BCFTs) describing the critical points of the Ising model on the strip. It consists in measuring the low-l…
Excitation Spectrum at the Yang-Lee Edge Singularity of 2D Ising Model on the Strip
Smain Balaska, John F. McCabe, Tomasz Wydro
At the Yang-Lee edge singularity, finite-size scaling behavior is used to measure the low-lying excitation spectrum of the Ising quantum spin chain for free boundary conditions. Th…
The boundary states and correlation functions of the tricritical Ising model from the Coulomb-gas formalism
S. Balaska, T. Sahabi
We consider the minimal conformal model describing the tricritical Ising model on the disk and on the upper half plane. Using the coulomb-gas formalism we determine its consistents…
Correlation Functions of The Tri-critical 3-states Potts Model
S. Balaska, K. Demmouche
We build the Z invariants fusion rules associated to the (D,A) conformal algebra. This algebra is known to describe the tri-critical Potts model. The 4-pt correla…
On the critical behaviour of hermitean f-matrix models in the double scaling limit with f >= 3
S. Balaska, J. Maeder, W. Ruehl
An algorithm for the isolation of any singularity of f-matrix models in the double scaling limit is presented. In particular it is proved by construction that only those universali…
The Continuous Series of Critical Points of the Two-Matrix Model at N -> infinity in the Double Scaling Limit
S. Balaska, J. Maeder, W. Ruehl
The critical points of the continuous series are characterized by two complex numbers l_1,l_2 (Re(l_1,l_2)< 0), and a natural number n (n>=3) which enters the string susceptibility…
Perturbative approach to the critical behaviour of two-matrix models in the limit N -> infinity
S. Balaska, J. Maeder, W. Ruehl
We construct representations of the Heisenberg algebra by pushing the perturbation expansion to high orders. If the multiplication operators tend to differential operator…
