Quantum walker trapped by self-similarity of the Sierpiński carpet
Tomasz Sowiński
We study the dynamics of a single quantum particle on a finite-size square lattice with a fractal structure resembling the Sierpiński carpet, and compare it to the dynamics on a un…
Pair-correlation ansatz for the ground state of interacting bosons in an arbitrary one-dimensional potential
Przemysław Kościk, Arkadiusz Kuroś, Adam Pieprzycki +1
We derive and describe a very accurate variational scheme for the ground state of the system of a few ultra-cold bosons confined in one-dimensional traps of arbitrary shapes. It is…
Quantum walk versus classical wave: Distinguishing ground states of quantum magnets by spacetime dynamics
Piotr Wrzosek, Krzysztof Wohlfeld, Damian Hofmann +2
We investigate the wavepacket spreading after a single spin flip in prototypical two-dimensional ferromagnetic and antiferromagnetic quantum spin systems. We find characteristic sp…
Exactly solvable model of two interacting Rydberg-dressed atoms confined in a two-dimensional harmonic trap
Przemysław Kościk, Tomasz Sowiński
Exactly solvable model of two Rydberg-dressed atoms moving in a quasi-two-dimensional harmonic trap is introduced and its properties are investigated. Depending on the strength of…
One-dimensional mixtures of several ultracold atoms: a review
Tomasz Sowiński, Miguel Ángel García-March
Recent theoretical and experimental progress on studying one-dimensional systems of bosonic, fermionic, and Bose-Fermi mixtures of a few ultracold atoms confined in traps is review…
Momentum correlations of a few ultra-cold bosons escaping from an open well
Jacek Dobrzyniecki, Tomasz Sowiński
The dynamical properties of a one-dimensional system of two and three bosons escaping from an open potential well are studied in terms of the momentum distributions of particles. I…
