Study on quasi-isothermal expansion process of compressed air based on spray heat transfer

open access: yesEnergy Reports, 2022
The piston expander with compressed air as working medium has been widely studied for its advantages of cleanliness, reliability and safety, but its application is limited by low exhaust temperature and low output power/efficiency.

Driving three atoms into a singlet state in an optical cavity via adiabatic passage of a dark state

open access: yes, 2012
In this paper, we propose an efficient scheme to drive three atoms in an optical cavity into a singlet state via adiabatic passage. Appropriate Rabi frequencies of the classical fields are selected to realize the present scheme.

Non-Gaussianity from Inflation [PDF]

open access: yes, 2002
Correlated adiabatic and isocurvature perturbation modes are produced during inflation through an oscillation mechanism when extra scalar degrees of freedom other than the inflaton field are present.

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

open access: yesAdvanced Materials, EarlyView.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...

NUMERICAL ANALYSIS OF GAS-DROPLET CHEMICAL PLUG-FLOW REACTOR OPERATING MODES

open access: yesВестник Донского государственного технического университета, 2018
A one-dimensional model and numerical solution of the non-stationary modes of the adiabatic gas-droplet chemical plug-flow reactor are considered. The developed approach permits to investigate processes of heat and mass transfer in the laminar flow of ...

Perovskite Microwires for Room Temperature Exciton‐Polariton Neural Network

open access: yesAdvanced Materials, EarlyView.
Exciton‐polaritons are explored as a novel platform for optical neuromorphic computing at room temperature using a monocrystalline perovskite waveguide. Demonstrating non‐equilibrium Bose‐Einstein condensation, this work achieves machine learning tasks such as classification and object detection, marking a key advance toward energy‐efficient, practical

Quantum heat engine based on quantum interferometry: The SU(1,1) Otto cycle

open access: yesPhysical Review Research
We present a quantum heat engine based on a quantum Otto cycle whose working substance reproduces the same outcomes as an SU(1,1) interference process at the end of each adiabatic transformation.

Optimum electrode configurations for fast ion separation in microfabricated surface ion traps

open access: yes, 2011
For many quantum information implementations with trapped ions, effective shuttling operations are important. Here we discuss the efficient separation and recombination of ions in surface ion trap geometries.
