The spin-1 two-dimensional J1-J2 Heisenberg antiferromagnet on a triangular lattice
P. Rubin, A. Sherman, M. Schreiber
The spin-1 Heisenberg antiferromagnet on a triangular lattice with the nearest- and next-nearest-neighbor couplings, and , , is studied in the entire rang…

The t-J model on a semi-infinite lattice
A. Sherman, N. Voropajeva
The hole spectral function of the t-J model on a two-dimensional semi-infinite lattice is calculated using the spin-wave and noncrossing approximations. In the case of small hole c…
