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…
