Statistical Physics- The Boson Systems
"In this note 'n' Boson Hamiltonian and 'n' boson energy eigenstates for a free boson
system has been considered.It shows how by choosing proper Hamiltonian we can determine the statistics of identical particles. A brief look at Fermi statistics is given.Numerical examples has been solved. A vibratingstring picture of 1D boson system, the second quantized description of free boson, vacuum as a dynamical medium and the Casimir eﬀect, classical ﬁeld theory for nonrelativistic free boson, Collective modes – sound wave, Quantized collective modes – phonon, an oscillator picture for the sound wave has been explained.
