Copy of Ch5-Chemical Reactions in Solutions
... In chemistry, the mole is the standard measurement of amount. When substances react according to chemical equations, they do so in simple ratios of moles. However, balances give readings in grams. Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substanc ...

Collective molecule formation in a degenerate
... resonance superfluids [9] inherit an analog of this trait of BCS superconductors. Nonetheless, suggestive as the similarity may be, the BCS instability is different from the present one. The thermodynamic instability occurs because pairing lowers the energy, and so coupling to a reservoir with a low e ...

8. LASER COOLING AND TRAPPING OF NEUTRAL ATOMS 8.1
... technique is velocity-selective coherent population trapping, or VSCPT, in which atoms are optically pumped into a coupled atomic/momentum state that decouples from the laser field for momenta equal to ::1:hkL [28, 29]. This method has also recently been demonstrated in two and three dimensions [30, ...
