Phase diagram study of a two-dimensional frustrated antiferromagnet via unsupervised machine learning
S. Acevedo, M. Arlego, C. A. Lamas
We apply unsupervised learning techniques to classify the different phases of the antiferromagnetic Ising model on the honeycomb lattice. We construct the phase diagram o…
Magnon crystals and magnetic phases in a Kagomé-stripe antiferromagnet
S. Acevedo, C. A. Lamas, M. Arlego +1
In this work we analyze the magnetization properties of an antiferromagnetic Kagomé stripe lattice, motivated by the recent synthesis of materials exhibiting this structure. By emp…
Quantum phase diagram of a frustrated antiferromagnet on the bilayer honeycomb lattice
Hao Zhang, Carlos A. Lamas, Marcelo Arlego +1
We study the spin-1/2 Heisenberg antiferromagnet on a bilayer honeycomb lattice including interlayer frustration. Using a set of complementary approaches, namely Schwinger bosons,…
Self consistent study of the quantum phases in a frustrated antiferromagnet on the bilayer honeycomb lattice
M. Arlego, C. A. Lamas, H. Zhang
We study the frustrated Heisenberg model on the bilayer honeycomb lattice. The ground-state energy and spin gap are calculated, using different bosonic representations at mean fiel…
Magnetization plateaux and jumps in a frustrated four-leg spin tube under a magnetic field
F. A. Gómez Albarracín, M. Arlego, H. D. Rosales
We study the ground state phase diagram of a frustrated spin-1/2 four-leg spin tube in an external magnetic field. We explore the parameter space of this model in the regime of all…
Series Expansion Analysis of a Frustrated Four-Spin-Tube
Marcelo Arlego, Wolfram Brenig
We study the magnetism of a frustrated four-leg spin-1/2 ladder with transverse periodic boundary conditions: the frustrated four-spin tube (FFST). Using a combination of series ex…
