Exploring magneto-electric coupling through lattice distortions: insights from a pantograph model
Daniel C. Cabra, Gerardo L. Rossini
Multiferroic materials exhibit the coexistence of magnetic and electric order. They are at the forefront of modern condensed matter physics due to their potential applications in n…
Anisotropic frustrated Heisenberg model on the honeycomb lattice
A. Kalz, M. Arlego, D. Cabra +2
We investigate the ground-state phase diagram of an anisotropic Heisenberg model on the honeycomb lattice with competing interactions. We use quantum Monte Carlo simulations, as we…
Resonances in a dilute gas of magnons and metamagnetism of isotropic frustrated ferromagnetic spin chains
M. Arlego, F. Heidrich-Meisner, A. Honecker +2
We show that spin-S chains with SU(2)-symmetric, ferromagnetic nearest-neighbor and frustrating antiferromagnetic next-nearest-neighbor exchange interactions exhibit metamagnetic b…
Spin-Peierls-like phases in magnetoelastic antiferromagnetic chain at 1/3 magnetization
H. D. Rosales, G. L. Rossini
We investigate elastic deformations of spin antiferromagnetic Heisenberg chains, at magnetization, coupled to phonons in the adiabatic approximation. Usin…
Comparison between disordered quantum spin 1/2 chains
C. A. Lamas, D. C. Cabra, M. D. Grynberg +1
We study the magnetic properties of two types of one dimensional XX spin 1/2 chains. The first type has only nearest neighbor interactions which can be either antiferromagnetic or…
Transition from Abelian to non-Abelian FQHE states
D. C. Cabra, A. Lopez, G. L. Rossini
We study the transition from the Abelian multi-component (3,3,1) quantum Hall state to the non-Abelian one component Pfaffian state in bilayer two dimensional electron systems. We…
