Dimensional crossover in alternating spin chains
Adolfo E. Trumper, Claudio J. Gazza
The effect of antiferromagnetic interchain coupling in alternating spin (1,1/2) chains is studied by mean of spin wave theory and density matrix renormalization group(DMRG). Two li…
Antiferromagnetically coupled alternating spin chains
Adolfo E. Trumper, Claudio Gazza
The effect of antiferromagnetic interchain coupling in alternating spin (1,1/2) chains is studied by mean of a spin wave theory and density matrix renormalization group (DMRG). In…
Finite size Spin Wave theory of the triangular Heisenberg model
Adolfo E. Trumper, Luca Capriotti, Sandro Sorella
We present a finite size spin wave calculation on the Heisenberg antiferromagnet on the triangular lattice focusing in particular on the low-energy part of the excitation spectrum.…
Spin wave analysis to the spatially-anisotropic Heisenberg antiferromagnet on triangular lattice
Adolfo E. Trumper
We study the phase diagram at T=0 of the antiferromagnetic Heisenberg model on the triangular lattice with spatially-anisotropic interactions. For values of the anisotropy very clo…
Schwinger-boson approach to quantum spin systems: Gaussian fluctuactions in the "natural" gauge
A. E. Trumper, L. O. Manuel, C. J. Gazza +1
We compute the Gaussian-fluctuation corrections to the saddle-point Schwinger-boson results using collective coordinate methods. Concrete application to investigate the frustrated…
