What is the Bose-Einstein condensation? Write an expression of number of particles in the excited state (Nex) in terms of Bose-Einstein condensation temperature (Tc), total number of bosons (N) in an assembly and temperature T. Show a plot of distribution of bosons as a function of temperature below and above the Tc.
Bose-Einstein condensation (BEC) is a phase transition that occurs in a system of non-interacting bosons at very low temperatures, where a macroscopic number of particles occupy the lowest quantum state. At temperatures below a critical temperature (T_c), the bosons "condense" into the ground state, leading to quantum phenomena on a macroscopic scale. For an ideal Bose gas, the total number of particles (N) is given by the sum of particles in the ground state ((N_0)) __________ ____ __________ ________ ________.
