The exploration of quantum spin liquids (QSLs) has been guided by different approaches
including the resonating valence bond (RVB) picture, deconfined lattice gauge theories, and …

Trimers are defined as two adjacent edges on a graph. We study the quantum states
obtained as equal-weight superpositions of all trimer coverings of a lattice, with the …

Abstract Using quantum Monte Carlo, exact diagonalization, and perturbation theory, we
study the spectrum of the S= 1/2 antiferromagnetic Heisenberg trimer chain by varying the …

We study perfect matchings, or close-packed dimer coverings, of finite sections of the eleven
Archimedean lattices and give a constructive proof showing that any two perfect matchings …

We investigate the excitation spectra of a spin-1/2 antiferromagnetic Heisenberg trimer spin
chain by employing a combination of numerical and theoretical techniques. Utilizing the …

We study the quantum Newman-Moore model, or quantum triangular plaquette model
(qTPM), in the presence of a longitudinal field (qTPMz). We present evidence that indicates …

We investigate the excitation spectra of a spin-1/2 antiferromagnetic Heisenberg trimer spin
chain by employing a combination of numerical and theoretical techniques. Utilizing the …

We present a variational matrix product state (vMPS) for the ground state of the spin-1/2
Heisenberg model. The MPS effectively organizes the various dimer configurations, in …
