Dynamics of Macroscopic Wave Packet Passing through Double Slits: Role of Gravity and Nonlinearity
Katsuhiro Nakamura, Naofumi Nakazono, Taro Ando
Using the nonlinear Schroedinger equation (Gross-Pitaevskii equation), the dynamics of a macroscopic wave packet for Bose-Einstein condensates falling through double slits is analy…
A model for conservative chaos constructed from multi-component Bose-Einstein condensates with a trap in 2 dimensions
Hisatsugu Yamasaki, Yuhei Natsume, Katsuhiro Nakamura
To show a mechanism leading to the breakdown of a particle picture for the multi-component Bose-Einstein condensates(BECs) with a harmonic trap in high dimensions, we investigate t…
Energy diffusion in frustrated quantum spin chains exhibiting Gaussian orthogonal ensemble level statistics
Kazue Kudo, Katsuhiro Nakamura
Frustrated quantum spin chains with the next-nearest-neighbor (NNN) couplings are typically deterministic many-body systems exhibiting Gaussian orthogonal ensemble (GOE) spec…
