Dissipation through localised loss in bosonic systems with long-range interactions
Ivana Vidanovic, Daniel Cocks, Walter Hofstetter
In recent years, controlled dissipation has proven to be a useful tool for probing of a quantum system in the ultracold setup. In this paper we consider dynamics of bosons induced…
Spin modulation instabilities and phase separation dynamics in trapped two-component Bose condensates
Ivana Vidanovic, N. J. van Druten, Masudul Haque
In the study of trapped two-component Bose gases, a widely used dynamical protocol is to start from the ground state of a one-component condensate and then switch half the atoms in…
Geometric Resonances in Bose-Einstein Condensates with Two- and Three-Body Interactions
Hamid Al-Jibbouri, Ivana Vidanovic, Antun Balaz +1
We investigate geometric resonances in Bose-Einstein condensates by solving the underlying time-dependent Gross-Pitaevskii equation for systems with two- and three-body interaction…
C programs for solving the time-dependent Gross-Pitaevskii equation in a fully anisotropic trap
Dusan Vudragovic, Ivana Vidanovic, Antun Balaz +2
We present C programming language versions of earlier published Fortran programs (Muruganandam and Adhikari, Comput. Phys. Commun. 180 (2009) 1888) for calculating both stationary…
Topological d-wave pairing structures in Jain states
N. Moran, A. Sterdyniak, I. Vidanovic +2
We discuss d-wave topological (broken time reversal symmetry) pairing structures in unpolarized and polarized Jain states. We demonstrate pairing in the Jain spin singlet state by…
Nonlinear Bose-Einstein-condensate Dynamics Induced by a Harmonic Modulation of the s-wave Scattering Length
Ivana Vidanovic, Antun Balaz, Hamid Al-Jibbouri +1
In a recent experiment, a Bose-Einstein condensate of Li7 has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an a…
SPEEDUP Code for Calculation of Transition Amplitudes via the Effective Action Approach
Antun Balaz, Ivana Vidanovic, Danica Stojiljkovic +3
We present Path Integral Monte Carlo C code for calculation of quantum mechanical transition amplitudes for 1D models. The SPEEDUP C code is based on the use of higher-order short-…
Fast Converging Path Integrals for Time-Dependent Potentials II: Generalization to Many-body Systems and Real-Time Formalism
Antun Balaz, Ivana Vidanovic, Aleksandar Bogojevic +2
Based on a previously developed recursive approach for calculating the short-time expansion of the propagator for systems with time-independent potentials and its time-dependent ge…
Ultra-Fast Converging Path-Integral Approach for Rotating Ideal Bose-Einstein Condensates
