sorry i cannot get the link to work, i did a google search for
feshbach resonance and came up with,
chapter 2 the 155 G Rb feshbach resonance 2.1 introduction 2.2
i do not understand all of it but perchance someone with more than my basic ganglion could give a simplified overview.[?]
I got the archive CD, but most others don't. Besides, likeOriginally posted by ranyart
This is over 2 yrs old, things have moved on a bit since then, and we covered this on the old forum? is there not acess to these postings? or has the database been collapsed?
A Bose Einstein condensate is a state of matter that occurs at extremely low temperatures when a large number of bosons (particles with integer spin) occupy the lowest energy state in a system, resulting in all particles behaving as a single entity.
A BEC can be made to attract by adjusting the interactions between the particles, typically through the use of a magnetic field. This can be achieved by tuning the magnetic field to a specific frequency, causing the particles to interact and attract each other.
BECs that can be made to attract have potential applications in quantum computing, precision measurements, and superfluidity. They can also be used to study fundamental physics and simulate complex quantum systems.
Creating a BEC that can be made to attract requires precise control over temperature, pressure, and magnetic fields. It also requires specialized equipment and techniques, as well as a thorough understanding of quantum mechanics.
In a BEC that can be made to attract, the particles are drawn towards each other and form a single entity, whereas in a BEC that can be made to repel, the particles are pushed away from each other and form a dilute gas. The properties and behavior of these two types of BECs are quite different and can be used for different purposes.
