A chiral spin liquid wave function and the Lieb-Schulz-Mattis theorem

S. Sorella, L. Capriotti, F. Becca +1

We study a chiral spin liquid wave function defined as a Gutwziller projected BCS state with a complex pairing function. After projection, spontaneous dimerization is found for any…

Suppression of Dimer Correlations in the Two-Dimensional $J_{1}$ - $J_{2}$ Heisenberg Model: an Exact Diagonalization Study

Luca Capriotti, Federico Becca, Alberto Parola +1

We present an exact diagonalization study of the ground state of the spin-half $J_{1} - J_{2}$ model. Dimer correlation functions and the susceptibility associated to the breaking of t…

Ground State of a Heisenberg Chain with Next-Nearest-Neighbor Bond Alternation

Luca Capriotti, Federico Becca, Sandro Sorella +1

We investigate the ground-state properties of the spin-half $J_{1} - J_{2}$ Heisenberg chain with a next-nearest-neighbor spin-Peierls dimerization using conformal field theory and Lan…
