On Repeated Measurements of a Quantum Particle in a Harmonic Potential
Filip Gampel, Mariusz Gajda
We study evolution of a quantum particle in a harmonic potential whose position and momentum are repeatedly monitored. A back-action of measuring devices is accounted for. Our mode…
Continuous simultaneous measurement of position and momentum of a particle
Filip Gampel, Mariusz Gajda
We formulate a model of a quantum particle continuously monitored by detectors measuring simultaneously its position and momentum. We implement the postulate of wavefunction collap…
Pauli crystals in harmonic trap and on a sphere
Filip Gampel, Mariusz Gajda, Magdalena Załuska-Kotur +1
Recently predicted and observed Pauli crystals are structures formed by trapped ultracold non-interacting particles obeying Fermi statistics. The relative positions of the particle…
Atoms in a spin dependent optical potential: ground state topology and magnetization
Piotr Szulim, Marek Trippenbach, Y. B. Band +2
We investigate a Bose-Einstein condensate of Rb atoms in a 2D spin-dependent optical lattice generated by intersecting laser beams with a superposition of polarizatio…
Quasicondensation reexamined
Przemyslaw Bienias, Krzysztof Pawlowski, Mariusz Gajda +1
We study in detail the effect of quasicondensation. We show that this effect is strictly related to dimensionality of the system. It is present in one dimensional systems independe…
Statistical properties of one dimensional attractive Bose gas
Przemyslaw Bienias, Krzysztof Pawlowski, Mariusz Gajda +1
Using classical field approximation we present the first study of statistical properties of one dimensional Bose gas with attractive interaction. The canonical probability distribu…
Statistical properties of one dimensional Bose gas
Przemyslaw Bienias, Krzysztof Pawlowski, Mariusz Gajda +1
Monte Carlo method within, so called, classical fields approximation is applied to one dimensional weakly interacting repulsive Bose gas trapped in a harmonic potential. Equilibriu…
Exact dynamics and decoherence of two cold bosons in a 1D harmonic trap
Tomasz Sowinski, Miroslaw Brewczyk, Mariusz Gajda +1
We study dynamics of two interacting ultra cold Bose atoms in a harmonic oscillator potential in one spatial dimension. Making use of the exact solution of the eigenvalue problem o…
