$J_{1} - J_{2}$ Quantum Heisenberg Antiferromagnet: Improved Spin-Wave Theories Versus Exact-Diagonalization Data

N. B. Ivanov, J. Richter

We reconsider the results cocerning the extreme-quantum $S = 1/2$ square-lattice Heisenberg antiferromagnet with frustrating diagonal couplings ( $J_{1} - J_{2}$ model) drawn from a compari…

On The Violation Of Marshall-Peierls Sign Rule In The Frustrated $J_{1} - J_{2}$ Heisenberg Antiferromagnet

J. Richter, N. B. Ivanov, K. Retzlaff

We present a number of arguments in favor of the suggestion that the Marshall-Peierls sign rule survives the frustration in the square-lattice Heisenberg antiferromagnet with frust…
