Wang-Landau study of the triangular Blume-Capel ferromagnet
N. G. Fytas
We report on numerical simulations of the two-dimensional Blume-Capel ferromagnet embedded in the triangular lattice. The model is studied in both its first- and second-order phase…
On non-abelian T-dual geometries with Ramond fluxes
Konstadinos Sfetsos, Daniel C. Thompson
We show how to implement T-duality along non-abelian isometries in backgrounds with non-vanishing Ramond fields. When the dimension of the isometry group is odd (even) the duality…
The Non-Compact Weyl Equation
Anastasia Doikou, Theodora Ioannidou
A non-compact version of the Weyl equation is proposed, based on the infinite dimensional spin zero representation of the sl_2 algebra. Solutions of the aforementioned equation are…
Non-Markovian Dynamics and Entanglement of Two-level Atoms in a Common Field
C. H. Fleming, N. I. Cummings, Charis Anastopoulos +1
We derive the stochastic equations and consider the non-Markovian dynamics of a system of multiple two-level atoms in a common quantum field. We make only the dipole approximation…
Universality in disordered systems: The case of the three-dimensional random-bond Ising model
Nikolaos G. Fytas, Panagiotis E. Theodorakis
We study the critical behavior of the Ising model with bond randomness through extensive Monte Carlo simulations and finite-size scaling techniques. Our results indicate that…
Microphase separation in linear multiblock copolymers under poor solvent conditions
Panagiotis E. Theodorakis, Nikolaos G. Fytas
Molecular dynamics simulations are used to study the phase behavior of linear multiblock copolymers with two types of monomers, A and B, where the length of the polymer blocks $N_{…
