Universality away from critical points in two-dimensional phase transitions
Cintia M. Lapilli, Peter Pfeifer, Carlos Wexler
The p-state clock model in two dimensions is a system of discrete rotors with a quasi-liquid phase in a region T1 < T < T2 for p > 4. We show that, for p > 4 and above a temperatur…
Collective excitations in quantum Hall liquid crystals: Single-mode approximation calculations
Cintia M. Lapilli, Carlos Wexler
A variety of recent experiments probing the low-temperature transport properties of quantum Hall systems have suggested an interpretation in terms of liquid crystalline mesophases…
Liquid crystalline states for two-dimensional electrons in strong magnetic fields
Orion Ciftja, Cintia M. Lapilli, Carlos Wexler
Based on the Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory of two-dimensional melting and the analogy between Laughlin states and the two-dimensional one-component plasm…
Testing boundary conditions efficiency in simulations of long-range interacting magnetic models
Sergio A. Cannas, Cintia M. Lapilli, Daniel A. Stariolo
Periodic boundary conditions have not a unique implementation in magnetic systems where all spins interact with each other through a power law decaying interaction of the form $1/r…
