Theory of atomistic simulation of spin-transfer torque in nanomagnets
Tiamhock Tay, L. J. Sham
In spin-transfer torque (STT) for technological applications, the miniaturization of the magnet may reach the stage of requiring a fully quantum-mechanical treatment. We present an…
Sign structures for short-range RVB states on small kagome clusters
Tiamhock Tay, Olexei I. Motrunich
We extended the Schwinger boson construction to obtain wave functions that are resonating valence bond (RVB) counterparts of the degenerate coplanar classical states on the Kagome…
Variational study of J1-J2 Heisenberg model on Kagome lattice using projected Schwinger boson wave functions
Tiamhock Tay, Olexei I. Motrunich
Motivated by the unabating interest in the spin-1/2 Heisenberg antiferromagnetic model on the Kagome lattice, we investigate the energetics of projected Schwinger boson (SB) wave f…
Failure of Gutzwiller-type wave function to capture gauge fluctuations: Case study in the Exciton Bose Liquid context
Tiamhock Tay, Olexei I. Motrunich
Slave particle approaches are widely used in studies of exotic quantum phases. A complete description beyond mean field also contains dynamical gauge fields, while a simplified pro…
Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Tiamhock Tay, Olexei I. Motrunich
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a term acts on 11 plaquettes and a term acts on 12 and 2$\tim…
Study of a hard-core boson model with ring-only interactions
Tiamhock Tay, Olexei I. Motrunich
We present a Quantum Monte Carlo study of a hardcore boson model with ring-only exchanges on a square lattice, where a term acts on 11 plaquettes and a term act…
