Comment on the paper ``Decoherence and the theory of continuous quantum measurements'', by M. B. Mensky, Phys. Usp. 41, 923 (1998), arXiv:quant-ph/9812017v2
Roberto Onofrio, Carlo Presilla
In quant-ph/9812017v2 M.B. Mensky reviewed our application of the restricted path integral approach to quantum measurements of energy. In this comment we point out that Mensky's as…

Dissipationless flow and superfluidity in gaseous Bose-Einstein condensates
C. Raman, R. Onofrio, J. M. Vogels +2
We study dissipation in a dilute Bose gas induced by the motion of a macroscopic object. A blue-detuned laser beam focused on the center of a trapped gas of sodium atoms was scanne…
