We used matter-wave interference to measure the correlation length of these critical fluctuations as a function of temperature. Observations of the diverging behavior of the correlation length above the critical temperature enabled us to determine the critical exponent of the correlation length for a trapped, weakly interacting Bose gas to be v = 0.67 :f: 0.13. This measurement has direct implications for the understanding of second-order phase transitions. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
