“…With the development of the techniques for manipulating ultracold atoms, a variety of double-well atom interferometers [30,35] have been introduced to estimate single parameter. As an extension of the single parameter estimation with the double-well, we come up with using a symmetrical triple-well [45][46][47][48][49] that confined bosonic atoms to study the two-parameter estimation.…”

We propose a theoretical scheme to realize two-parameter estimation via a Bose-Einstein condensates confined in a symmetric triple-well. The three-mode NOON state is prepared adiabatically as the initial state. Two phase differences between the wells are two parameters to be estimated. With the help of classical and quantum Fisher information, we study the sensitivity of the triplewell on estimating two phase parameters simultaneously. The result shows that the precision of simultaneous estimation of two parameters in a triple-well system can reach the Heisenberg scaling.

The International Year of Light 2015 was a landmark for the laser and optics community pointing the way to a bright future for humanity and the environment. It is with great satisfaction that Laser Physics and Laser Physics Letters have published many notable articles that have contributed to the development of light-based technologies and breakthroughs in photonics. In recognition of their high quality, we present a selection of some of the most popular articles published by Laser Physics and Laser Physics Letters throughout 2015, all of which are believed to have the potential to make a high impact on future research directions. Those chosen are recognised for their high-interest with readers and importance in the field, providing a snapshot of the broad subject coverage and international make-up of both journals.Starting this year, we will be recognising and announcing annual highlights of a previous year for both journals. We hope that you find these highlights useful and look forward to publishing more cutting-edge work in the year ahead.Summary of the highlights articles: Physics of lasers• • Experimental investigation of the light shift effect in an optical-magnetic double resonance system-an experimental scheme for studying the light shift effect in an optical magnetic double resonance system by using 4 He atoms is demonstrated [3]. • Enhanced random lasing from a colloidal CdSe quantum dot-Rh6G system-randomlaser action in a system where optical amplification is provided by colloidal CdSe quantum dots triggered by the emission from Rhodamine 6 G is reported [4].• Ultra-short pulse generation in the hybridly mode-locked erbium-doped all-fiber ring laser with a distributed polarizer-ultra-short pulse generation in a dispersion-managed erbium-doped all-fiber ring laser hybridly mode-locked with boron nitride-doped singlewalled carbon nanotubes, in co-action with a nonlinear polarization evolution in the ring cavity with a distributed polarizer, is reported for the first time [5].• Analysis of pump excited state absorption and its impact on laser efficiency-a model to quantify the effect of excited state absorption at the pump wavelength on laser efficiency, threshold and heating is developed [6].

“…Related interesting topics and properties, in other contexts, on the dynamics of more than one condensate have been extensively reported, such as spatio-temporal and low-energy dynamical behaviors in arrays of Bose-Einstein condensates [19][20][21][22][23], resonances, phase fluctuation, critical behavior and time-delayed polaritons in two coupled condensates [24][25][26][27][28][29][30][31][32][33], and interference effects, self-trapping, chaotic behavior, quantum transition and parity effects in three coupled condensates [34][35][36][37][38][39][40][41]. Geometries with more sites and leads would somewhat make the analysis more complicated.…”

Emission of particles from a parametrically driven condensate in a one-dimensional lattice

We investigate particle emission, driven by periodically modulating the interaction strength, from three coupled Bose-Einstein condensates in a one-dimensional lattice. Within perturbative analyses, which lead to the regimes of instabilities for different modes, we not only obtain two main frequencies, under which the system can emit a large particle jet, but also find that the emission is distinctly intermittent rather than continuous. The time evolution of the trapped particles exhibits a stairlike decay, and a larger drive induces a more significant intermittency. We further shed light on the dynamics of the stimulating process, and demonstrate that instead of a real suspension, the intermittency represents a build-up stage of the particles. The theoretical framework might be generalized, to the explorations on other multiple-condensate systems with analogous configurations and couplings.
