Demon-like Algorithmic Quantum Cooling and Its Realization with Quantum Optics
Demon-like Algorithmic Quantum Cooling Quantum Optics
2016/1/22
Simulation of the low-temperature properties of many-body systems remains one of the major challenges in theoretical 1–3 and experimental 4–6 quantum information science. We present, and demonstrate e...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
Molecular Phylogenetic Diversity and Spatial Distribution of Bacterial Communities in Cooling Stage during Swine Manure Composting
Diversity Restriction Fragment Length Polymorphism
2016/5/18
Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and subsequent sub-cloning and sequencing were used in this study to analyze the molecular phylogenetic diversity and spat...
An experimental study of pyroxene crystallization during rapid cooling in a thermal gradient: application to komatiites
Pyroxene crystallization mattie rocks thermal gradient cooling rapidly komatiite lava flow
2015/1/6
To investigate the crystallization of pyroxene in spinifex-textured komatiites, we undertook a series of experiments in which compositions in the CaO-MgO-Al2O3-SiO2 CMAS system were cooled rapidly in ...
We examine the cooling radiation from forming galaxies in hydrodynamic simulations of the LCDM model (cold dark matter with a cosmological constant), focusing on the Lyα line luminosities of high-reds...
A common feature of the X-ray bubbles observed in Chandra images of some "cooling flow" clusters is that they appear to be surrounded by bright, cool shells. Temperature maps of a few nearby luminous ...
Using high-resolution cosmological simulations, we study hydrogen and helium gravitational cooling radiation from gas accretion by young galaxies. We focus on the He II cooling lines, which arise from...
Powerful H$_2$ Line-cooling in Stephan's Quintet : I - Mapping the Significant Cooling Pathways in Group-wide Shocks,
intergalactic medium shock waves
2014/12/22
We present results from the mid-infrared spectral mapping of Stephan's Quintet using the Spitzer Space Telescope. A 1000 km/s collision has produced a group-wide shock and for the first time the large...
On the algorithms of radiative cooling in semi-analytic models
semi-analytic models galaxy
2014/12/22
We study the behaviour of multiple radiative cooling algorithms implemented in six Semi-Analytic Models (SAMs) of galaxy formation, including a new model we propose in this paper. We use versions of t...
Theory of cooling by flow through narrow pores
Dilution chillers cooling heat atoms quantum states
2014/12/20
We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by “filtering out” hot atoms. Three methods are considered: (1) effusion, where holes having diam...
Numerical model of crustal accretion and cooling rates of fast-spreading mid-ocean ridges
Numerical model crustal accretion cooling rates fast-spreading mid-ocean ridges
2014/12/12
We designed a thermo-mechanical numerical model for fast-spreading mid-ocean ridge with variable viscosity, hydrothermal cooling, latent heat release, sheeted dyke layer, and variable melt intrusion p...
Fundamental Limit to Atom-Ion Sympathetic Cooling in Paul Traps
Atom-Ion Sympathetic Paul Traps Atomic Physics
2012/5/31
We present a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done by the trap electric field during a long-range ion-atom...
Ground state sideband cooling of an ion in a room temperature trap with a sub-Hertz heating rate
Ground state sideband ion sub-Hertz heating rate Atomic Physics
2012/5/29
We demonstrate resolved sideband laser cooling of a single 40Ca+ ion in a macroscopic linear radio frequency trap with a radial diagonal electrode spacing of 7 mm and an rf drive frequency of just 3.7...

Cavity-meidated collisionless sympathetic molecules atoms Atomic Physics
2012/5/29
Cooling a range of molecules to ultracold temperatures (<1 mK) is a difficult but important challenge in molecular physics and chemistry. Collective cavity cooling of molecules is a promising method t...
The study of neutron stars is a topic of central interest in the investigation of the properties of strongly compressed hadronic matter. Whereas in heavy-ion collisions the fireball, created in the co...
