Towards chemistry at absolute zero by Heazlewood, B, Softley, T

“…The prospect of cooling matter down to temperatures that are close to absolute zero raises intriguing questions about how chemical reactivity changes under these extreme conditions. …”

'... a metal conducts and a non-metal doesn't'. by Edwards, P, Lodge, M, Hensel, F, Redmer, R

“…Here, we review the issues-theoretical and experimental-attendant on studies of the metal to non-metal transition in doped semiconductors at temperatures close to absolute zero (T=0.03 K) and fluid chemical elements at temperatures far above absolute zero (T>1000 K). …”

On determining absolute entropy without quantum theory or the third law of thermodynamics by Steane, A

“…It follows from all these examples that the value of entropy at absolute zero temperature does not need to be assigned by postulate, but can be deduced empirically.…”

Witnessing macroscopic entanglement in a staggered magnetic field by Hide, J, Son, W, Lawrie, I, Vedral, V

“…Using single-site entropy and by constructing an entanglement witness, we search for the existence of entanglement when the system is at absolute zero, as well as in thermal equilibrium. Although the role of the alternating magnetic field b is, in general, to suppress entanglement as do B and T, we find that when T=0, introducing b allows the existence of entanglement even when the uniform magnetic field B is arbitrarily large. …”

Heat capacity as an indicator of entanglement by Wiesniak, M, Vedral, V, Brukner, C

“…The idea is that if the system was in a separable state, then for certain Hamiltonians heat capacity would not tend asymptotically to zero as the temperature approaches absolute zero. Since this would contradict the third law of thermodynamics, one concludes that the system must contain entanglement. …”

REACTION-RATES OF IONS WITH DIPOLAR MOLECULES IN 2-PI ELECTRONIC STATES by Wickham, A, Stoecklin, T, Clary, D

“…The most interesting new prediction is that the rate coefficient for the reaction of a 2Π polar molecule with an ion is proportional to T-1/2 for temperatures close to absolute zero. © 1992 American Institute of Physics.…”

Detection of trapped molecular O2 in a charged Li-rich cathode by Neutron PDF by House, R, Playford, HY, Smith, R, Holter, J, Griffiths, I, Zhou, K-J, Bruce, PG

“…This was achieved by collecting our data close to absolute zero (2K), suppressing thermal motion which may have obscured detection by PDF previously. …”
