Dynamical Quantum Phase Transitions in presence of a spin bath
Álvaro Gómez-León, P. C. E. Stamp
We derive an effective time independent Hamiltonian for the transverse Ising model coupled to a spin bath, in the presence of a high frequency AC magnetic field. We show that the s…
Inertial and fluctuational effects on the motion of a Bose superfluid vortex
T. Cox, P. C. E. Stamp
We study the motion of a vortex under the influence of a harmonic force in an approximately two dimensional trapped Bose-condensed gas. The Hall-Vinen-Iordanskii equations, modifie…
Vortex Dynamics: Quantum versus Classical Regimes
L. Thompson, P. C. E. Stamp
For many years the classical Hall-Vinen-Iordanski (HVI) equation has been used to analyse vortex dynamics in superfluids. Here we discuss the extension of the theory of vortex dyna…
Quantum Dynamics of a Bose Superfluid Vortex
L. Thompson, P. C. E. Stamp
We derive a fully quantum-mechanical equation of motion for a vortex in a 2-dimensional Bose superfluid, in the temperature regime where the normal fluid density is small.…
Sharp transition for single polarons in the one-dimensional Su-Schrieffer-Heeger model
D. J. J. Marchand, G. De Filippis, V. Cataudella +5
We study a single polaron in the Su-Schrieffer-Heeger (SSH) model using four different techniques (three numerical and one analytical). Polarons show a smooth crossover from weak t…
Low temperature universality in disordered solids
M. Schechter, P. C. E. Stamp
The low temperature universal properties in disordered and amorphous solids are considered. We introduce a model that includes two types of two level systems (TLSs), which, based o…
