Phase diagram of ferrimagnetic ladders with bond-alternation
A. Langari, M. Abolfath, M. A. Martin-Delgado
We study the phase diagram of a 2-leg bond-alternation spin-(1/2, 1) ladder for two different configurations using a quantum renormalization group approach. Although d-dimensional…
Finite Temperature Behavior of the Quantum Hall Effect in Bilayer Electron Systems
M. Abolfath, Ramin Golestanian, T. Jungwirth
An effective field theoretic description of bilayer electron systems stabilized by Coulomb repulsion in a single wide quantum well is examined using renormalization group tec…
Quantum Ferrimagnets
M. Abolfath, H. Hamidian, A. Langari
We study quantum ferrimagnets in one, two, and three dimensions by using a variety of methods and approximations. These include: (i) a treatment based on the spin coherent state pa…
