Excitations and spin correlations near the interface of two three-dimensional Heisenberg antiferromagnets
N. Voropajeva, A. Sherman
Magnetic excitations and spin correlations near the interface of two spin- Heisenberg antiferromagnets are considered using the spin-wave approximation. When the interacti…
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…
Near-Boundary and Bulk Regions of a Semi-Infinite Two-Dimensional Heisenberg Antiferromagnet
N. Voropajeva, A. Sherman
Using the spin-wave approximation elementary excitations of a semi-infinite two-dimensional Heisenberg antiferromagnet are considered. The spectrum consists of bulk mod…
Spin correlations near the surface of a three-dimensional Heisenberg antiferromagnet
N. Voropajeva, A. Sherman
Nearest-neighbor spin correlations are considered near the surface of a semi-infinite spin- Heisenberg antiferromagnet on a simple cubic lattice. In the spin-wave approxim…
Excitations near the boundary between a metal and a Mott insulator
A. Sherman, N. Voropajeva
A heterostructure of a semi-infinite metal and a Mott insulator is considered. It is supposed that both materials have an identical lattice spacing and hopping integrals and differ…
Correlation in the velocity of a Brownian particle induced by frictional anisotropy and magnetic field
N. Voropajeva, T. Ord
We study the motion of charged Brownian particles in an external magnetic field. It is found that a correlation appears between the components of particle velocity in the case of a…
