Wannier functions for quasi-periodic finite-gap potentials
E. D. Belokolos, V. Z. Enolskii, M. Salerno
In this paper we consider Wannier functions of quasi-periodic g-gap () potentials and investigate their main properties. In particular, we discuss the problem of averaging…
Magnetization-induced optical third-harmonic generation in Co and Fe nanostructures
O. A. Aktsipetrov, E. M. Kim, R. V. Kapra +1
Magnetization-induced optical third-harmonic generation (MTHG) is observed in magnetic nanostructures: Co and Fe nanolayers and granular films containing Co nanoparticles. Magnetiz…
Hyperelliptic addition law
Victor Buchstaber, Dmitry Leykin
We construct an explicit form of the addition law for hyperelliptic Abelian vector functions and . The functions and form a basis in the field of hyperelli…
Dynamics of anisotropic spin dimer system in strong magnetic field
A. K. Kolezhuk, V. N. Glazkov, H. Tanaka +1
Recently measured high-field ESR spectra of the spin dimer material TlCuCl3 are described within the framework of an effective field theory. A good agreement between the theory and…
Macroscopic Quantum Tunneling in Small Antiferromagnetic Particles: Effects of a Strong Magnetic Field
B. A. Ivanov, V. E. Kireev
We consider an effect of a strong magnetic field on the ground state and macroscopic coherent tunneling in small antiferromagnetic particles with uniaxial and biaxial single-ion an…
Semiclassical dynamics of domain walls in the one-dimensional Ising ferromagnet in a transverse field
B. A. Ivanov, H. -J. Mikeska
We investigate analytically and numerically the dynamics of domain walls in a spin chain with ferromagnetic Ising interaction and subject to an external magnetic field perpendicula…
Field-induced disorder in a gapped spin system with non-magnetic impurities
H. -J. Mikeska, Asimkumar Ghosh, A. K. Kolezhuk
We study S=1/2 dimers which are weakly coupled by three-dimensional antiferromagnetic interactions J'. It is commonly known that doping with non-magnetic impurities immediately ind…
Excitation hierarchy of the quantum sine-Gordon spin chain in strong magnetic field
S. A. Zvyagin, A. K. Kolezhuk, J. Krzystek +1
The magnetic excitation spectrum of copper pyrimidine dinitrate, a material containing S=1/2 antiferromagnetic chains with alternating g-tensor and the Dzyaloshinskii-Moriya intera…
Wannier functions of elliptic one-gap potentials
E D Belokolos, V Z Enolskii, M Salerno
Wannier functions of the one dimensional Schroedinger equation with elliptic one gap potentials are explicitly constructed. Properties of these functions are analytically and numer…
