The Cooling Effect of Oasis Reservoir‐Riparian Forest Systems in Arid Regions

open access: yesWater Resources Research, Volume 60, Issue 10, October 2024.
Abstract In arid regions with limited water resources, numerous reservoirs have been built to support economic and social development. However, how the construction of reservoirs interacts with the surrounding ecosystem to affect temperature remains unclear. Spanning 2018 to 2022 in the Shiyang River Basin, we collected surface water and precipitation,

Polarization entanglement and quantum beats of photon pairs from four-wave mixing in a cold 87Rb ensemble

open access: yesNew Journal of Physics, 2015
We characterize correlations in polarization and time of photon pairs generated from a cold cloud of ^87 Rb atoms via a four-wave mixing process in a cascade level scheme.

Generation of amplitude-squeezed light from a room-temperature Fabry-Perot semiconductor laser [PDF]

open access: yes, 1995
Amplitude-squeezed light with intensity fluctuations 29% below the standard quantum limit (SQL) is produced from a pump-suppressed room-temperature semiconductor laser, corresponding to 41% below the SQL after correction for detection efficiency. Excess

Acute stress differently modulates interneurons excitability and synaptic plasticity in the primary motor cortex of wild‐type and SOD1G93A mouse model of ALS

open access: yesThe Journal of Physiology, Volume 602, Issue 19, Page 4987-5015, 1 October 2024.
Abstract figure legend Using the amyotrophic lateral sclerosis (ALS) mouse model SOD1G93A at a late presymptomatic stage (10–12.5 weeks), we aimed to determine the effect of acute restraint stress on the M1 excitatory/inhibitory balance under physiological (wild‐type, WT) and pathological (SOD1G93A) conditions.

Experimental quantum tomography of a homodyne detector

open access: yesNew Journal of Physics, 2017
We suggest and demonstrate a tomographic method to characterise homodyne detectors at the quantum level. The positive operator measure associated with the detector is expanded in a quadrature basis and probed with a set of coherent states.

Force sensing based on coherent quantum noise cancellation in a hybrid optomechanical cavity with squeezed-vacuum injection

open access: yesNew Journal of Physics, 2016
We propose and analyse a feasible experimental scheme for a quantum force sensor based on the elimination of backaction noise through coherent quantum noise cancellation (CQNC) in a hybrid atom-cavity optomechanical setup assisted with squeezed vacuum ...

Independent telecom-fiber sources of quantum indistinguishable single photons

open access: yesNew Journal of Physics, 2014
Quantum-mechanically indistinguishable photons produced by independent (or equivalently, mutually phase incoherent) light sources are essential for distributed quantum information processing applications.

Single Cooper pair tunneling induced by non-classical microwaves

open access: yes, 1996
A mesoscopic Josephson junction interacting with a mode of non-classical microwaves with frequency $\omega$ is considered. Squeezing of the electromagnetic field drastically affects the dynamics of Cooper tunneling.

Proposal for a loophole-free violation of Bell's inequalities with a set of single photons and homodyne measurements

open access: yesNew Journal of Physics, 2014
We demonstrate that different kinds of mesoscopic quantum states of light can be efficiently generated from a simple iterative scheme. These states exhibit strong non-classical features, and could be of great interest for many applications such as ...

Spontaneous four-wave mixing in liquid-core fibers: towards fibered Raman-free correlated photon sources

open access: yesNew Journal of Physics, 2015
We experimentally demonstrate, for the first time to our knowledge, the generation of correlated photon pairs in a liquid-core photonic crystal fiber. Moreover, we show that, thanks to the specific Raman properties of liquids, the Raman noise (which is ...
