Field-induced states and thermodynamics of the frustrated Heisenberg antiferromagnet on a square lattice

Andreas Honecker, M. E. Zhitomirsky, Alexander Wietek +1

We investigate the ground-state and finite-temperature properties of the $J_{1}$ - $J_{2}$ Heisenberg antiferromagnet on the square lattice in the presence of an external magnetic field.…

Thermodynamics of the spin-1/2 Heisenberg antiferromagnet on the star lattice

Adrien Reingruber, Nils Caci, Stefan Wessel +1

Using a combination of quantum Monte Carlo simulations in adapted cluster bases, the finite temperature Lanczos method, and an effective Hamiltonian approach, we explore the thermo…

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…
