چکیده
It is shown that, with an appropriate scaling, the energy of low-lying excitations of the (1, 1,. .. , 1) interface in the d-dimensional quantum Heisenberg model are given by the spectrum of the d − 1-dimensional Lapla-cian on an suitable domain.

Motivated by recent experiments that detects Dzyaloshinskii-Moriya (DM) interaction in , we study the effects of DM interaction on magnetic orders of J1-J2 antiferromagnetic Heisenberg model. First, we find the classical phase diagram of the model using Luttinger-Tisza approximation. In this approximation, the classical phase diagram has two phases. For , the model has canted Neel and DM intera...
متن کاملA Continuum Shell-beam Finite Element Modeling of Buried Pipes with 90-degree Elbow Subjected to Earthquake Excitations
In the current work, the seismic analysis of bent region in buried pipes is performed, and effects of soil properties and modeling methods on pipe’s response are investigated. To do this task Beam, Beam-Shell Finite Element modeling and a Continuum shell FE models of a 90 degrees elbow are employed. In the Beam model, the pipe is simulated by beam elements while combined shell-beam elements a...
متن کاملLineshape Predictions via Bethe Ansatz for the One-dimensional Spin-1/2 Heisenberg Antiferromagnet in a Magnetic Eld
The spin uctuations parallel to the external magnetic eld in the ground state of the one-dimensional (1D) s = 1 2 Heisenberg antiferromagnet are dominated by a two-parameter set of collective excitations. In a cyclic chain of N sites and magnetization 0 < Mz < N=2, the ground state, which contains 2Mz spinons, is reconngured as the physical vacuum for a diierent species of quasi-particles, iden...

We study the ground state and low-lying excitations of the S = 1/2 XXZ antiferromagnet on the kagomé lattice at magnetization one third of the saturation. An exponential number of non-magnetic states is found below a magnetic gap. The non-magnetic excitations also have a gap above the ground state, but it is much smaller than the magnetic gap. This ground state corresponds to an ordered pattern...
