Title: | MATHEMATICAL THEORY AND NUMERICAL METHODS FOR BOSE-EINSTEIN CONDENSATION WITH HIGHER ORDER INTERACTIONS | Authors: | RUAN XINRAN | Keywords: | modified Gross-Pitaevskii equation, dimension reduction, ground state, dynamics, fundamental gap, asymptotic approximation | Issue Date: | 13-Jan-2017 | Citation: | RUAN XINRAN (2017-01-13). MATHEMATICAL THEORY AND NUMERICAL METHODS FOR BOSE-EINSTEIN CONDENSATION WITH HIGHER ORDER INTERACTIONS. ScholarBank@NUS Repository. | Abstract: | The modified Gross-Pitaevskii equation is studied in a systematical way, both theoretically and numerically. Problems such as the dimension reduction, existence and uniqueness of the ground state, generalized or new computation schemes for computing ground states and dynamics are included in the thesis. Besides, I also studied the fundamental gap problem for the Gross-Pitaevskii equation and the ground state approximations of the nonlinear Schrödinger equation, which consists a minor part of my thesis. | URI: | http://scholarbank.nus.edu.sg/handle/10635/135445 |
