| Summary: | 碩士 === 國立彰化師範大學 === 物理學系 === 105 === In this thesis, we study the structural change of Rydberg-dressed Bose-Einstein condensate in two and three dimensions. In two dimensional case, under the harmonic trap, there exists a critical value of the dimensionless parameter α_c such that the system exhibits crystal long range order when α > α_c. When α < α_c, the ring structure may appear. The structural phase diagram is also determined.
In three dimensional case, its phase diagram is qualitatively similar to the two dimensional case except that there is a spherical shell structure instead of the ring structure.
