Magnetic excitations in the spin-1 anisotropic Heisenberg antiferromagnetic chain system NiCl(2)-4SC(NH(2))(2).
NiCl(2)-4SC(NH(2))(2) (DTN) is a quantum S=1 chain system with strong easy-pane anisotropy and a new candidate for the Bose-Einstein condensation of the spin degrees of freedom. ESR studies of magnetic excitations in DTN in fields up to 25 T are presented. Based on analysis of the single-magnon excitation mode in the high-field spin-polarized phase and previous experimental results [Phys. Rev. ...
متن کاملField-driven phase transitions in a quasi-two-dimensional quantum antiferromagnet
We report magnetic susceptibility, specific heat, and neutron scattering measurements as a function of applied magnetic field and temperature to characterize the S = 1/2 quasi-two-dimensional frustrated magnet piperazinium hexachlorodicuprate (PHCC). The experiments reveal four distinct phases. At low temperatures and fields the material forms a quantum paramagnet with a 1 meV singlet triplet g...
متن کاملLocal Spin-Gauge Symmetry of the Bose-Einstein Condensates in Atomic Gases.
The Bose-Einstein condensates of alkali atomic gases are spinor fields with local “spin-gauge” symmetry. This symmetry is manifested by a superfluid velocity us (or gauge field) generated by the Berry phase of the spin field. In “static” traps, us splits the degeneracy of the harmonic energy levels, breaks the inversion symmetry of the vortex nucleation frequency Ωc1, and can lead to vortex gro...

The Bose-Einstein condensation of a dilute gas of rubidium-87 atoms was achieved by cooling a small number of atoms in a magnetic trap. The effective potential of the trap is to lowest order harmonic and under these conditions we estimate the critical temperature and the heat capacity of an ideal gas of Bose particles. Previously this has been estimated within the semiclassical approximation. H...
متن کاملBose-Einstein condensation and entanglement in magnetic systems
We present a study of magnetic field induced quantum phase transitions in insulating systems. A generalized scaling theory is used to obtain the temperature dependence of several physical quantities along the quantum critical trajectory (H = HC , T → 0) where H is a longitudinal external magnetic field and HC the critical value at which the transition occurs. We consider transitions from a spin...
