  journal={Physical Review A},
In the present paper we investigate the influence of measurements on the quantum dynamics of degenerate Bose atoms gases in a symmetric double-well. We show that continuous measurements enhance asymmetry on the density distribution of the atoms and broaden the parameter regime for self-trapping. We term this phenomenon as nonlinear quantum Zeno effect in analog to the celebrated Zeno effect in a linear quantum system. Under discontinuous measurements, the self-trapping due to the atomic… 
Quantum Zeno effect in self-sustaining systems: Suppressing phase diffusion via repeated measurements
We study the effect of frequent projective measurements on the dynamics of quantum selfsustaining systems, by considering the prototypical example of the quantum Van der Pol oscillator. Quantum
Unsharp continuous measurement of a Bose-Einstein condensate: Full quantum state estimation and the transition to classicality
We study a Bose-Einstein condensate (BEC) in a double-well potential subject to an unsharp continuous measurement of the atom number in one of the two wells. We investigate the back action of the
Dynamics of a driven optical lattice with distance-selective dissipation
We analyze the dynamics of Bose–Einstein condensates in a one-dimensional driven optical lattice in the presence of distance-selective dissipation. The interplay of on-site interactions, tunneling,
Linear and nonlinear quantum Zeno and anti-Zeno effects in a nonlinear optical coupler
Quantum Zeno and anti-Zeno effects are studied in a symmetric nonlinear optical coupler, which is composed of two nonlinear ($\chi^{\left(2\right)}$) waveguides that are interacting with each other
Self-Trapping and Dynamical Stability of Two-Component Bose-Einstein Condensates in a Double-Well Potential
The dynamics of two-component Bose–Einstein condensates (BECs) in a double-well potential is studied here. Interspecies (or component–component) couplings are taken into account. As a consequence of
Macroscopic superposition states of ultracold bosons in a double-well potential
We present a thorough description of the physical regimes for ultracold bosons in double wells, with special attention paid to macroscopic superpositions (MSs). We use a generalization of the
A theoretical study of nonclassical effects in optical and spin systems and their applications
This work has examined generation of various lower- and higher-order nonclassical states in both codirectional and contradirectional asymmetric nonlinear optical couplers operating under second harmonic generation with the help of moments-based criteria and obtained the performance of a set of cryptographic schemes over non-Markovian channels.
Nonlinear tunneling through a strong rectangular barrier
Nonlinear tunneling is investigated by analytically solving the one-dimensional Gross–Pitaevskii equation (GPE) with a strong rectangular potential barrier. With the help of analytical solutions of


Quantum theory and measurement
The forty-nine papers collected here illuminate the meaning of quantum theory as it is disclosed in the measurement process. Together with an introduction and a supplemental annotated bibliography,
