Quantum Mechanics II
Consider the linear potential V = al.]. Use a Gaussian = exp(-Bx?) as the trial wave function, and calculate the ground state energy with the variational principle. De- termine the parameter B which minimizes the energy, and find Emin Express Emin = f x (hop/2m)1/3, and give the numerical value of the factor f. This is the upper bound of the true ground state energy, E Compare Emin with the exact result, E. = 1.019 (1?o?/2m)/3, and...

2. The unational method is an incredibly simple but surprisingly powerful method for understanding the low- energy behavior of quantu systems. It is used constantly in marny-body physics and in quantum chemistry. The main idea is thst for any physical Hamiltonian, there is a lowest energy state, i.e. the ground state Ipo). All other states (ignoring degeneracy) have higher energy that this one. Therefore we have Therefore, to get an upper bound on the energy of Eo, it suffices to...

In order to obtain the energy scale estimation of proton and neutron, use the Wilson- Sommerfeld rules. As quarks move away from each other, the colored lines of the force contract into string-like energy-dense regions. In order to establish the phenomenological model in which the energy input is proportional to the distance from the central coordinate Assuming linear potential: V(x) kr The masses of the upper and lower quarks are thought to be much smaller than the masses of the...
