Consider three particles, each of mass m, moving in one dimension and bound to eachother by harmonic forces, i.e., V=k/2*[(x_1-x_2)^2+(x_2-x_3)^2+(x_3-x_1)^2]
1) Write the (time-independent) schrodinger equation for the system.
2) Transform to a new coordinate system (having the center of mass as one of the coordinates), so that one can readily solve for the energy eigenvalues and the corresponding eigenfunctions explicitly.
3) Using the result of 2), find the ground state energy if the particles are identical spin-0 bosons.
4) What is the ground state energy if the particles are identical spin-1/2 fermions?
A man throws a baseball straight up in the air at 19.6 m/s. How many seconds does it take to reach the top
A car is traveling along a straight road at a velocity of +31.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is a1.
A group of physics students are conduction an experiment in projectile motion. find the time of flight for the ball in their experiment
In brief explain the changes that the Sun will go through after it exhausts its core hydrogen. Be sure to describe both the changes occurring in the Sun's core and the changes visible from outside the Sun. What do we mean by the stages we call hydrog..
Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity.
The slope of the velocity time graph is the instantaneous acceleration. Instantaneous velocity is the derivative of the displacement time function. Average acceleration and instantaneous acceleration are always the same.
An electron is in a certain energy state in a one-dimensional,infinite potential well from x = 0 to x =L = 250 pm. What is the change in the electron's energy
