Problem (M-1). The dispersion along the first band of a material is given by:

E(k) = 0.03k6 - 0.36k^4 + 1.95k^2 on the [110] axis of the Brillouin Zone. If k = 3 Å^-1, graph the dispersion. Then graph the velocity of the given electrons as a function of k along the [110] direction.

(25%) Problem 6: A mass m = 0.85 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 85 N/m and negligible mass. The mass undergoes simple harmonic motion when placed in vertical motion, with its position given as a function of time by y(t) = A cos(ωt – φ), with the positive y-axis pointing upward. At time t = 0 the mass is observed to...

Two particles move along an x axis. The position of particle 1 is given by x = 10.0t2 + 6.00t + 4.00 (in meters and seconds); the acceleration of particle 2 is given by a = -9.00t (in meters per seconds squared and seconds) and, at t = 0, its velocity is 24.0 m/s. When the velocities of the particles match, what is their velocity?

The dispersion relation for capillary-gravity waves on the surface of water ω = (gk + σk^3/ρ)^1/2. Here g = 9.81 m/s is the acceleration due to gravity,σ = 0.047 N/m is the surface tension of water, and = 1000kg/m3 is its density. Calculate the group velocity for these waves and plot it as a function of wavelength λ, where of course λ = 2π/k. The group velocity is a minimum for a particular value of λ. What is that value,...

A force F= -F0 e(-x/λ ) (where F0 and λ are positive constants) acts on a particle of mass m that is initially at x = x0 and moving with velocity v0 (> 0). Show that the velocity of the particle is given by, v(x) = ± ( v02 + (2F0λ/m)(e-x/λ - 1) ) 1/2 , where the upper (lower) sign corresponds to the motion in the positive (negative) x direction. Consider first the upper sign. For simplicity, define ve...
