Electrostatically-Driven Granular Media: Phase Transitions and Coarsening
I. S. Aranson, D. Blair, V. A. Kalatsky +4
We report the experimental and theoretical study of electrostatically driven granular material. We show that the charged granular medium undergoes a hysteretic first order phase tr…
Large moments in external fields of cubic group symmetry
V. A. Kalatsky, V. L. Pokrovsky
We predict that large moments , placed into a crystal field with the cubic point symmetry group, differ by their spectrum and magnetic properties. E. g., properties of the odd-i…
Berry's phase for large spins in external fields
V. A. Kalatsky, E. Müller--Hartmann, V. L. Pokrovsky +1
It is shown that even for large spins the fundamental difference between integer and half-integer spins persists. In a quasi-classical description this difference enters via Be…
Magnetic Structure of Rare-Earth Nickel Boride-Carbides
V. A. Kalatsky, V. L. Pokrovsky
We present a theory of the magnetic rare-earth nickel boride-carbides (RENiBC, RE=Ho, Er, Tm). Large total angular momentum allows one to employ semiclassical approximation…
