Sunny.jl: A Julia Package for Spin Dynamics
David Dahlbom, Hao Zhang, Cole Miles +16
Sunny is a Julia package designed to serve the needs of the quantum magnetism community. It supports the specification of a very broad class of spin models and a diverse suite of n…
Machine learning assisted derivation of effective low energy models for metallic magnets
Vikram Sharma, Zhentao Wang, Cristian D. Batista
We consider the problem of extracting an effective low-energy spin model from a Kondo Lattice Model (KLM) with classical localized moments. The non-analytic dependence of the effec…
Skyrmion Crystals in the Triangular Kondo Lattice Model
Zhentao Wang, Cristian D. Batista
We present a systematic study of the formation of skyrmion crystals in a triangular Kondo Lattice model for generic electron filling fractions. Our results indicate that the four-s…
Resistivity minimum in diluted metallic magnets
Zhentao Wang, Cristian D. Batista
Resistivity minima are commonly seen in itinerant magnets and they are often attributed to the Kondo effect. However, recent experiments are revealing an increasing number of mater…
Anomalous Magnetoresistance due to Longitudinal Spin Fluctuations in a Jeff = 1/2 Mott Semiconductor
Lin Hao, Zhentao Wang, Junyi Yang +12
As a hallmark of electronic correlation, spin-charge interplay underlies many emergent phenomena in doped Mott insulators, such as high-temperature superconductivity, whereas the h…
Vison Crystals in an Extended Kitaev Model on the Honeycomb Lattice
Shang-Shun Zhang, Zhentao Wang, Gábor B. Halász +1
We introduce an extension of the Kitaev honeycomb model by including four-spin interactions that preserve the local gauge structure and hence the integrability of the original mode…
Principal Chiral Model in Correlated Electron Systems
Cristian D. Batista, Mikhail Shifman, Zhentao Wang +1
We discuss noncollinear magnetic phenomena whose local order parameter is characterized by more than one spin vector. By focusing on the simple cases of 2D triangular and 3D pyroch…
Dynamics and Instabilities of the Shastry-Sutherland Model
Zhentao Wang, Cristian D. Batista
We study the excitation spectrum in the dimer phase of the Shastry-Sutherland model by using an unbiased variational method that works in the thermodynamic limit. The method output…
Gradient-based stochastic estimation of the density matrix
Zhentao Wang, Gia-Wei Chern, Cristian D. Batista +1
Fast estimation of the single-particle density matrix is key to many applications in quantum chemistry and condensed matter physics. The best numerical methods leverage the fact th…
Semiclassical dynamics of spin density waves
Gia-Wei Chern, Kipton Barros, Zhentao Wang +2
We present a theoretical framework for equilibrium and nonequilibrium dynamical simulation of quantum states with spin-density-wave (SDW) order. Within a semiclassical adiabatic ap…
Resistivity Minimum in Highly Frustrated Itinerant Magnets
Zhentao Wang, Kipton Barros, Gia-Wei Chern +2
We study the transport properties of frustrated itinerant magnets comprising localized {\it classical} moments, which interact via exchange with the conduction electrons. Strong fr…
Three-Dimensional Crystallization of Vortex Strings in Frustrated Quantum Magnets
Zhentao Wang, Yoshitomo Kamiya, Andriy H. Nevidomskyy +1
We demonstrate that frustrated exchange interactions can produce exotic 3D crystals of vortex strings near the saturation field (H=Hsat) of body- and face-centered cubic Mott insul…
