In this chapter, it is shown that the energy of a spin system may be written as E = NuB tanh[uB/kgT]. Consider a system of electron spins S = 1/2 and g = 2 in a magnetic field of 1 T. Find the temperature at which the magnetization of the system reaches 90% of the saturation value. Repeat the cal- culation for solid helium-3 nuclear spins for which I = 1/2 and μ = 2.2 nuclear magnetons.

Physics Show a sequence of beta reductions, using the context-and-redex grammars for enforcing CBV evaluation order, for the term (((λ (m) (λ (q) m)) (λ (m) m)) ((λ (a) a) (λ (b) c))).

In a fully degenerate gas, all the particles have energies lower than the Fermi energy. Using the provided equation for the Fermi energy (EF), and assuming a white dwarf star has a temperature T = 107 K and a mass M = 1Msun, evaluate numerically the ratio Eth/EF, where Eth is the characteristic thermal energy of an electron in a gas of temperature T, to prove that the electrons inside a white dwarf are indeed degenerate. (Hint: Estimate the characteristic density (ne) based on the given conditions inside a white dwarf)
The brightest star in the sky is Sirius, the Dog Star. Itis actually a binary system of two stars, the smaller one (Sirius B)being a white dwarf. Spectral analysis of Sirius B indicates that itssurface temperature is 24 000 K and that it radiates energy at a totalrate of 1.0 · 1025 W. Assume that it behaves like an ideal blackbody.(a) What is the radius of Sirius B? Express your answer in kilometersand as a fraction of our Sun’s radius (R= 6.96 · 108 m). (b) Whichstar radiates more total energy per second, the hot Sirius B or the(relatively) cool Sun with a surface temperature of T = 5800 K? Tofind out, calculate the ratio of the total power radiated by our Sun tothe power radiated by Sirius B.
