Finite size effects in the Z_2 spin liquid on the kagome lattice
Hyejin Ju, Leon Balents
Motivated by the recent discovery of the Z_2 quantum spin liquid state in the nearest neighbor Heisenberg model on the kagome lattice, we investigate the "even-odd" effect occuring…
Ground States of Spin-1/2 Triangular Antiferromagnets in a Magnetic Field
Ru Chen, Hyejin Ju, Hong-Chen Jiang +2
We use a combination of density matrix renormalization group calculations and analytical approaches to study a simplified model for a spatially anisotropic spin-1/2 triangular latt…
Entanglement in gapless resonating valence bond states
Jean-Marie Stéphan, Hyejin Ju, Paul Fendley +1
We study resonating-valence-bond (RVB) states on the square lattice of spins and of dimers, as well as SU(N)-invariant states that interpolate between the two. These states are gro…
Entanglement scaling in two-dimensional gapless systems
Hyejin Ju, Ann B. Kallin, Paul Fendley +2
We numerically determine subleading scaling terms in the ground-state entanglement entropy of several two-dimensional (2D) gapless systems, including a Heisenberg model with Néel o…
