We propose an optical Maxwell demon which efficiently captures, concentrates, and damps the kinetic motion of sodium atoms in a gas cell. A bath of radiation tuned just below resonance can prove to be a very viscous medium for atoms. We propose to use this effect to produce and concentrate very slow atoms in a vapor cell. Our bath of radiation consists

Contemporary Physics, 1995
Abstract This paper considers the concept of a Maxwell' demon based on the use of selective interaction between laser light and atomic particles. The following two possibilities are examined: destructive and non-destructive versions of the laser Maxwell's demon. The destructive version is based on the velocity-and particle-selective resonant ionization

Il Nuovo Cimento B Series 11, 1994
The problem of velocity selection by Maxwell’s demon in a many-particle gas, as distinct from a one-particle gas, is addressed. For such a situation it is shown that it is impossible to effect a separation of the molecules into two separate partitions so as to bring about an overall decrease in entropy unless information entropy is made available to ...

Nature, 1999
Careful experiments have revealed that the laws of nature (or at least elementary particles called kaons) can distinguish between past and future. Numerical calculations based on the Standard Model of particle physics now predict different results for such experiments. Is this a hint of physics beyond the Standard Model?

Maxwell's demon in biological systems
Acta Biotheoretica, 1976Boltzmann's gas model representing the second law of thermodynamics is based on the improbability of certain molecular distributions in space. Maxwell argued that a hypothetical 'being' with the faculty of seeing individual molecules (Maxwell's Demon) could bring about such improbable distributions, thus violating the law of entropy.

Molecular cell, 2002
FtsK, which links chromosome segregation and cell division in E. coli, has now been shown to be an ATP-dependent DNA translocase. It also activates XerCD-dependent recombination, converting chromosome dimers into monomers, by switching the order of strand cleavage by the recombinase subunits.
