Heisenberg model with Dzyaloshinskii-Moriya interaction: A Schwinger boson study
L. O. Manuel, C. J. Gazza, A. E. Trumper +1
We present a Schwinger-boson approach to the Heisenberg model with Dzyaloshinskii-Moriya interaction. We write the anisotropic interactions in terms of Schwinger bosons keeping the…

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…
