Diagnostics of macroscopic quantum states of Bose–Einstein condensate in double-well potential by nonstationary Josephson effect
We propose a method of diagnostics of a degenerate ground state of Bose condensate in a double- well potential. The method is based on the study of the one-particle coherent tunneling under switching of the time-dependent weak Josephson coupling between the wells. We obtain a simple expression th...

| description |
We propose a method of diagnostics of a degenerate ground state of Bose condensate in a double-
well potential. The method is based on the study of the one-particle coherent tunneling under
switching of the time-dependent weak Josephson coupling between the wells. We obtain a simple
expression that allows one to determine the phase of the condensate and the total number of the
particles in the condensate from the relative number of particles in the two wells Δn = n₁ -
n₂ measured
before the Josephson coupling is switched on and after it is switched off. The specifics of the
application of the method in the cases of the external and the internal Josephson effect are discussed. |
