A self-interacting two-level system depending on an external parameter is investigated. The
most striking feature exhibited in this system is the presence of a nonzero tunneling …

We investigate adiabatic evolution of quantum states as governed by the nonlinear Schrödinger
equation and provide examples of applications with a nonlinear tunneling model for …

Conspectus The assembly of discrete architectures has been an important subject in
supramolecular chemistry because of their elegant structures and fascinating properties. During the …

The superfluidity of Bose-Einstein condensates (BECs) in optical lattices is investigated. Apart
from the usual Landau instability, which occurs when a BEC flows faster than the speed of …

A tetrakis(bisurea)‐decorated tetraphenylethene (TPE) ligand (L 2 ) was designed, which,
upon coordination with phosphate ions, displays fluorescence “turn‐on” over a wide …

Nonlinear effects in the interference of Bose-Einstein condensates are studied using exact
solutions of the one-dimensional nonlinear Schrödinger equation, which is applicable when …

Graphene has good stability and adjustable dielectric properties along with tunable morphologies,
and hence can be used to design novel and high-performance functional materials. …

We study bright solitons in a Bose-Einstein condensate with a spin-orbit coupling that has
been realized experimentally. Both stationary bright solitons and moving bright solitons are …

Superflow of a Bose–Einstein condensate in an optical lattice is represented by a Bloch wave,
a plane wave with periodic modulation of the amplitude. We review the theoretical results …

We present a comprehensive analysis of the nonlinear Landau-Zener tunneling. We find
characteristic scaling or power laws for the critical behavior that occurs as the nonlinear …
