Packet 6: Bonus 12

Deborah S. Jin led the CU Boulder team that observed the first instance of an example of this type of matter in potassium-40. For 10 points each:
[10m] Name this general type of matter in which particles are accumulated into a single quantum state. The Gross–Pitaevskii equation models one example of this type of matter.
ANSWER: condensate [accept Bose–Einstein condensate or Fermi–Dirac condensate or fermionic condensate]
[10h] This scientist’s quasiparticles are the elementary excitations of BECs, whose Hamiltonian is diagonalized by a namesake transformation. This Soviet physicist originated the study of weakly interacting Bose gases.
ANSWER: Nikolay Bogoliubov [or Nikolay Nikolayevich Bogolyubov; accept Bogoliubov quasiparticles or Bogoliubov transformation]
[10e] The role of bogolons in superconductivity is analogous to the role of phonons in Debye’s (“duh-BYE’s”) model for this thermodynamic quantity. For water, this quantity is 4.18 Joules per Kelvin.
ANSWER: heat capacity [accept specific heat capacity; prompt on C-sub-v or C-sub-p]
