Curvature-Induced Skyrmion Mass
Alexander Pavlis, Christina Psaroudaki
We investigate the propagation of magnetic skyrmions on elastically deformable geometries by employing imaginary time quantum field theory methods. We demonstrate that the Euclidea…
Scattering of spinon excitations by potentials in the 1D Heisenberg model
A. Pavlis, X. Zotos
By a semi-analytical Bethe ansatz method and a T-matrix approach we study the scattering of a spinon, the elementary quantum many-body topological excitation in the 1D Heisenberg m…
Dressed excitations, thermodynamics and relaxation in the 1D XXZ Heisenberg model
A. Pavlis, X. Zotos
In this note, we discuss the low and high temperature contribution of Thermodynamic Bethe Ansatz (TBA) dressed excitations in the thermodynamics and energy-magnetization relaxation…
Evaluation of the performance of two state-transfer Hamiltonians in the presence of static disorder
Alexander K. Pavlis, Georgios M. Nikolopoulos, Peter Lambropoulos
We analyse the performance of two quantum-state-transfer Hamiltonians in the presence of diagonal and off-diagonal disorder, and in terms of different measures. The first Hamiltoni…
