Intercomponent correlations in attractive one-dimensional mass-imbalanced few-body mixtures
Daniel Pęcak, Tomasz Sowiński
Ground-state properties of a few attractively interacting ultra-cold atoms of different mass confined in a one-dimensional harmonic trap are studied in terms of the correlation noi…
Variational approach for interacting ultra-cold atoms in arbitrary one-dimensional confinement
Przemysław Kościk, Marcin Płodzień, Tomasz Sowiński
Standard analytical construction of the many-body wave function of interacting particles in one dimension, beyond mean-field theory, is based on the Jastrow approach. The many-body…
Dynamics of a few interacting bosons escaping from an open well
Jacek Dobrzyniecki, Tomasz Sowiński
The dynamics of a few ultra-cold bosons tunneling from a one-dimensional potential well into open space is studied. In such a system several decay channels can be distinguished, ea…
Few-fermion thermometry
Marcin Płodzień, Rafał Demkowicz-Dobrzański, Tomasz Sowiński
Potential realization of a quantum thermometer operating in the nanokelvin regime, formed by a few-fermionic mixture confined in a one-dimensional harmonic trap, is proposed. Therm…
Numerically exact approach to few-body problems far from a perturbative regime
Marcin Płodzień, Dariusz Wiater, Andrzej Chrostowski +1
Recent developments of experimental techniques in the field of ultra-cold gases open a path to study the crossover from 'few' to 'many' on the quantum level. In this case, accurate…
Ground-State Magnetization in Mixtures of a Few Ultra-Cold Fermions in One-Dimensional Traps
Tomasz Sowiński
Ground-state properties of a few spin- ultra-cold fermions confined in a one-dimensional trap are studied by the exact diagonalization method. In contrast to previous studies,…
Global optimization for quantum dynamics of few-fermion systems
Xikun Li, Daniel Pęcak, Tomasz Sowiński +2
Quantum state preparation is vital to quantum computation and quantum information processing tasks. In adiabatic state preparation, the target state is theoretically obtained with…
