Non-equilibrium scale invariance and shortcuts to adiabaticity in a one-dimensional Bose gas
Wolfgang Rohringer, Dominik Fischer, Florian Steiner +3
We present experimental evidence for scale invariant behaviour of the excitation spectrum in phase-fluctuating quasi-1d Bose gases after a rapid change of the external trapping pot…
LaBonte's method revisited: An effective steepest descent method for micromagnetic energy minimization
Lukas Exl, Simon Bance, Franz Reichel +3
We present a steepest descent energy minimization scheme for micromagnetics. The method searches on a curve that lies on the sphere which keeps the magnitude of the magnetization v…
Solving highly-oscillatory NLS with SAM: numerical efficiency and geometric properties
Philippe Chartier, Norbert J. Mauser, Florian Méhats +1
In this paper, we present the Stroboscopic Averaging Method (SAM), recently introduced in [7,8,10,12], which aims at numerically solving highly-oscillatory differential equations.…
Equivalence transformations in the study of integrability
Olena O. Vaneeva, Roman O. Popovych, Christodoulos Sophocleous
We discuss how point transformations can be used for the study of integrability, in particular, for deriving classes of integrable variable-coefficient differential equations. The…
Group classification and exact solutions of variable-coefficient generalized Burgers equations with linear damping
Oleksandr A. Pocheketa, Roman O. Popovych, Olena O. Vaneeva
Admissible point transformations between Burgers equations with linear damping and time-dependent coefficients are described and used in order to exhaustively classify Lie symmetri…
Quantum and thermal fluctuations in bosonic Josephson junctions
Bruno Julia-Diaz, Alex D. Gottlieb, Joan Martorell +1
We use the Bose-Hubbard Hamiltonian to study quantum fluctuations in canonical equilibrium ensembles of bosonic Josephson junctions at relatively high temperatures, comparing the r…
