Ultrawide dark solitons and droplet-soliton coexistence in a dipolar Bose gas with strong contact interactions
Jakub Kopyciński, Maciej Łebek, Wojciech Górecki +1
We look into dark solitons in a quasi-1D dipolar Bose gas and in a quantum droplet. We derive the analytical solitonic solution of a Gross-Pitaevskii-like equation accounting for b…
Multiparameter quantum metrology in the Heisenberg Limit regime: many repetition scenario vs. full optimization
Wojciech Górecki, Rafał Demkowicz-Dobrzański
We discuss the Heisenberg limit in the multiparameter metrology within two different paradigms -- the one, where the measurement is repeated many times (so the Cramér-Rao bound is…
Beyond Gross-Pitaevskii equation for 1D gas: quasiparticles and solitons
Jakub Kopyciński, Maciej Łebek, Maciej Marciniak +3
Describing properties of a strongly interacting quantum many-body system poses a serious challenge both for theory and experiment. In this work, we study excitations of one-dimensi…
Dark solitons revealed in Lieb-Liniger eigenstates
Weronika Golletz, Wojciech Górecki, Rafał Ołdziejewski +1
We study how dark solitons, i.e. solutions of one-dimensional single-particle nonlinear time-dependent Schrödinger equation, emerge from eigenstates of a linear many-body model of…
Many-body soliton-like states of the bosonic ideal gas
Rafał Ołdziejewski, Wojciech Górecki, Krzysztof Pawłowski +1
We study the lowest energy states for fixed total momentum, i.e. yrast states, of bosons moving on a ring. As in the paper of A. Syrwid and K. Sacha \cite{syrwid2015} , we comp…
Electric dipoles vs. magnetic dipoles - for two molecules in a harmonic trap
Wojciech Górecki, Kazimierz Rzążewski
We study energy levels of two heteronuclear molecules moving in a spherically symmetric harmonic trap. A role of electric dipole interactions is compared and contrasted with our ea…
Making two dysprosium atoms rotate - Einstein-de Haas effect revisited
Wojciech Górecki, Kazimierz Rzążewski
We present a numerical study of the behaviour of two magnetic dipolar atoms trapped in a harmonic potential and exhibiting the standard Einstein-de Haas effect while subject to a t…
Two dipolar atoms in a harmonic trap
Rafał Ołdziejewski, Wojciech Górecki, Kazimierz Rzążewski
Two identical dipolar atoms moving in a harmonic trap without an external magnetic field are investigated. Using the algebra of angular momentum a semi - analytical solutions are f…
