consider two identical particles in a 1D infinite square well of length L.
1. write the symmetric and anti-symmetric spatial ground state wave functions.
2. write the correct ground state wave function if the particles are electrons
3. write the correct ground state wave function if the particles are bosons with S equals to 1.
