Three-state Potts nematic order in stacked frustrated spin models with SO(3) symmetry
Ana-Marija Nedić, Victor L. Quito, Yuriy Sizyuk +1
We propose stacked two-dimensional lattice designs of frustrated and SO(3) symmetric spin models consisting of antiferromagnetic (AFM) triangular and ferromagnetic (FM) sixfold sym…
Learning crystal field parameters using convolutional neural networks
Noah F. Berthusen, Yuriy Sizyuk, Mathias S. Scheurer +1
We present a deep machine learning algorithm to extract crystal field (CF) Stevens parameters from thermodynamic data of rare-earth magnetic materials. The algorithm employs a two-…
Competing magnetic interactions in the antiferromagnetic topological insulator MnBiTe
J. -Q. Yan, D. Pajerowski, Liqin Ke +6
The antiferromagnetic (AF) compound MnBiTe is suggested to be the first realization of an antiferromagnetic (AF) topological insulator. Here we report on inelastic neut…
Quantum spin liquid in the semiclassical regime
Ioannis Rousochatzakis, Yuriy Sizyuk, Natalia B. Perkins
Quantum spin liquids have been at the forefront of correlated electron research ever since their original proposal in 1973, and the realization that they belong to the broader clas…
Kitaev-Heisenberg model in a magnetic field: order-by-disorder and commensurate-incommensurate transitions
Gia-Wei Chern, Yuriy Sizyuk, Craig Price +1
We present a theoretical study of field-induced magnetic phases in the honeycomb Kitaev-Heisenberg model, which is believed to describe the essential physics of Mott insulators wit…
Selection of direction of the ordered moments in NaIrO and RuCl
Yuriy Sizyuk, Peter Woelfle, Natalia B. Perkins
The magnetic orders in NaIrO and RuCl, honeycomb systems with strong spin-orbit coupling and correlations, have been recently described by models with the dominant…
The free energy of anisotropic quantum spin systems: Functional integral representation
Peter Woelfle, Natalia B Perkins, Yuriy Sizyuk
In this work, we propose a method for calculating the free energy of anisotropic quantum spin systems. We use the Hubbard-Stratonovich transformation to express the partition funct…
Lifting mean-field degeneracies in anisotropic classical spin systems
Yuriy Sizyuk, Natalia B. Perkins, Peter Wölfle
In this work, we propose a method for calculating the free energy of anisotropic classical spin systems. We use a Hubbard-Stratonovich transformation to express the partition funct…
A structural distortion induced magneto-elastic locking in SrIrO revealed through nonlinear optical harmonic generation
D. H. Torchinsky, H. Chu, L. Zhao +5
We report a global structural distortion in SrIrO using spatially resolved optical second and third harmonic generation rotational anisotropy measurements. A symmetry lower…
Importance of anisotropic exchange interactions in honeycomb iridates. Minimal model for zigzag antiferromagnetic order in NaIrO
Yuriy Sizyuk, Craig Price, Peter Wölfle +1
In this work, we investigate the microscopic nature of the magnetism in honeycomb iridium-based systems by performing a systematic study of how the effective magnetic interactions…
Interplay of many-body and single-particle interactions in iridates and rhodates
Natalia B. Perkins, Yuriy Sizyuk, Peter Wölfle
Motivated by recent experiments exploring the spin-orbit-coupled magnetism in - and -band transition metal oxides, we study magnetic interactions in Ir- and Rh-based compou…
