Many-body effects in quantum metrology
Jan Czajkowski, Krzysztof Pawłowski, Rafał Demkowicz-Dobrzański
We study the impact of many-body effects on the fundamental precision limits in quantum metrology. On the one hand such effects may lead to non-linear Hamiltonians, studied in the…
On the Dissipative Version of the Gross--Pitaevski Equation
K. Pawłowski, Ł. A. Turski
We propose a novel version of the dissipative Gross--Pitaevski equation and examine its properties. In contrast to previous proposals our approach, based on the metriplectic formul…
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…
