We investigate the dynamics of two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well potential. The effects of the three-body recombination loss and the feeding of the condensates from the thermal cloud are studied in the case of attra

The spatial structure of a Bose–Einstein condensate (BEC) loaded into an optical lattice potential is investigated and the spatially chaotic distributions of the condensates are revealed. A method of chaos control with linear feedback is presented

We present a scheme for chaotic synchronization in two resistive- capacitive-inductive shunted Josephson junctions (RCLSJJs) by using another chaotic RCLSJJ as a driving system. Numerical simulations show that whether the two RCLSJJs are chaotic or n

The resistively-capacitively-inductively-shunted (RCL-shunted) Josephson junction (RCLSJJ) shows chaotic behaviour under some parameter conditions. Here a scheme for controlling chaos in the RCLSJJ is presented based on the linear feedback theory. Nu

In this paper we present the control and synchronization of a coupled Bragg acousto-optic bistable map system using nonlinear feedback technology. This nonlinear feedback technology is useful to control a temporally chaotic system as well as a spatio

We have investigated the synchronization of chaotic dual-ring erbium-doped fibre lasers using the delay feedback–injection scheme. Numerical simulation shows that two chaotic dual-ring erbium-doped fibre lasers can be well synchronized if the stren

We present a method of anti-control of chaos on the degenerate optical parametric oscillator via modulating the reduced decay rate of the fundamental mode with a sinusoid wave to convert the steady state without output of subharmonical mode or period

This paper presents a method that restrains a systematical behavior by a synchronistical measure and forces it to repeat a section of chaotic trajectory periodically, so that the high periodic chaotic signal can be obtained. The obtained signal not o

A new method of controlling chaos of a laser diode by all external optical feedback was proposed according to the principle of Pyragas' method; the conditions in which the method can be used were given from theoritical analysis based on the coherence

The paper proposes theoretically the method of chaos synchronization by self-controlled feedback coupling-driving,and studies numerically on the condition of chaotic synchronization in two Bragg acousto-optic bistable (AOB) systems. The maximum condi
