From real fields to complex Calogero particles
Paulo E. G. Assis, Andreas Fring
We provide a novel procedure to obtain complex PT-symmetric multi-particle Calogero systems. Instead of extending or deforming real Calogero systems, we explore here the possibilit…
A spin chain model with non-Hermitian interaction: The Ising quantum spin chain in an imaginary field
Olalla A. Castro-Alvaredo, Andreas Fring
We investigate a lattice version of the Yang-Lee model which is characterized by a non-Hermitian quantum spin chain Hamiltonian. We propose a new way to implement PT-symmetry on th…
Spin-Transfer Torque in Helical Spin-Density Waves
O. Wessely, B. Skubic, L. Nordstrom
The current driven magnetisation dynamics of a helical spin-density wave is investigated. Expressions for calculating the spin-transfer torque of real systems from first principles…
The quantum-mechanical basis of an extended Landau-Lifshitz-Gilbert equation for a current-carrying ferromagnetic wire
D. M. Edwards, O. Wessely
An extended Landau-Lifshitz-Gilbert (LLG) equation is introduced to describe the dynamics of inhomogeneous magnetization in a current-carrying wire. The coefficients of all the ter…
Integrable models from PT-symmetric deformations
Paulo E. G. Assis, Andreas Fring
We address the question of whether integrable models allow for PT-symmetric deformations which preserve their intgrability. For this purpose we carry out the Painleve test for PT-s…
Symmetries of Spin Calogero Models
Vincent Caudrelier, Nicolas Crampe
We investigate the symmetry algebras of integrable spin Calogero systems constructed from Dunkl operators associated to finite Coxeter groups. Based on two explicit examples, we sh…
