Honeycomb-lattice Gamma model in a magnetic field: hidden Néel order and spin-flop transition
Zhongzheng Tian, Zhijie Fan, Preetha Saha +1
We show that a magnetic field in the high-symmetry direction lifts the macroscopic classical ground-state degeneracy of the honeycomb model and induces a long-range magnetic or…
Machine learning dynamics of phase separation in correlated electron magnets
Puhan Zhang, Preetha Saha, Gia-Wei Chern
We demonstrate machine-learning enabled large-scale dynamical simulations of electronic phase separation in double-exchange system. This model, also known as the ferromagnetic Kond…
Spin dynamics of the antiferromagnetic Heisenberg model on a kagome bilayer
Preetha Saha, Depei Zhang, Seung-Hun Lee +1
We study the spin dynamics of classical Heisenberg antiferromagnet with nearest neighbor interactions on a quasi-two-dimensional kagome bilayer. This geometrically frustrated latti…
Plaquette order in classical spin liquid stabilized by strong off-diagonal exchange
Preetha Saha, Zhijie Fan, Depei Zhang +1
We report a new classical spin liquid in which the collective flux degrees of freedom break the translation symmetry of the honeycomb lattice. This exotic phase exists in frustrate…
