A Guide to Applications of -Contact Geometry in Dissipative Field Equations
J. de Lucas, J. Lange, M. Krych
We study the practical scope of the -contact Hamilton--De Donder--Weyl formalism as a geometric framework for dissipative field equations. In particular, our work focuses on can…
Reactive collisions of polar molecules in quasi-two-dimensional traps
M. Krych, Z. Idziaszek
We investigate collisions of polar molecules in quasi-2D traps in the presence of an external electric field perpendicular to the collision plane. We use the quantum-defect model c…
Simple model of Feshbach resonance in the strong-coupling regime
T. Wasak, M. Krych, Z. Idziaszek +3
We use the dressed potentials obtained in the adiabatic representation of two coupled channels to calculate s-wave Feshbach resonances in a 3D spherically symmetric potential with…
Quantum defect model of a reactive collision at finite temperature
Krzysztof Jachymski, Michał Krych, Paul S. Julienne +1
We consider a general problem of inelastic collision of particles interacting with power-law potentials. Using quantum defect theory we derive an analytical formula for the energy-…
Description of ion motion in a Paul trap immersed in a cold atomic gas
Michał Krych, Zbigniew Idziaszek
We investigate the problem of a single ion in a radio-frequency trap and immersed in an ultracold Bose gas either in a condensed or a non-condensed phase. We develop master equatio…
Quantum theory of reactive collisions for 1/r^n potentials
Krzysztof Jachymski, Michal Krych, Paul S. Julienne +1
We develop a general quantum theory for reactive collisions involving power-law potentials (-1/r^n) valid from the ultracold up to the high-temperature limit. Our quantum defect fr…
Sympathetic cooling of the Ba ion by collisions with ultracold Rb atoms: theoretical prospects
Michał Krych, Wojciech Skomorowski, Filip Pawłowski +2
State-of-the-art {\em ab initio} techniques have been applied to compute the potential energy curves of the (BaRb) molecular ion in the Born-Oppenheimer approximation. The long…
An eccentrically perturbed Tonks-Girardeau gas
J. Goold, M. Krych, Z. Idziaszek +2
We investigate the static and dynamic properties of a Tonks-Girardeau gas in a harmonic trap with an eccentric -perturbation of variable strength. For this we first find the ana…
Controlled collisions of two ultracold atoms in separate harmonic traps
Michał Krych, Zbigniew Idziaszek
We consider controlled collisions between two ultracold atoms guided by external harmonic potentials. We derive analytical solutions of the Schroedinger equation for this system, a…
