Unified approach to Quantum and Classical Dualities
E. Cobanera, G. Ortiz, Z. Nussinov
We show how classical and quantum dualities, as well as duality relations that appear only in a sector of certain theories ("emergent dualities"), can be unveiled, and systematical…
Local physics of magnetization plateaux in the Shastry-Sutherland model
L. Isaev, G. Ortiz, J. Dukelsky
We address the physical mechanism responsible for the emergence of magnetization plateaux in the Shastry-Sutherland model. By using a hierarchical mean-field approach we demonstrat…
Field Induced Orbital Antiferromagnetism in Mott Insulators
K. A. Al-Hassanieh, C. D. Batista, G. Ortiz +1
We report on a new electromagnetic phenomenon that emerges in Mott insulators, i.e., materials that do not conduct electricity because of strong electronic Coulomb repulsion. The p…
Phase diagram of the Heisenberg antiferromagnet with four-spin interactions
L. Isaev, G. Ortiz, J. Dukelsky
We study the quantum phase diagram of the Heisenberg planar antiferromagnet with a subset of four-spin ring exchange interactions, using the recently proposed heirarchical mean-fie…
