Introduction to Quantum Statistical Thermodynamics
... theorem, asserts that bosons have integral spin and fermions have half-integral spin. Composite systems, e.g., atoms, also can exhibit bosonic or fermionic behavior. Which will it be? As it happens, if one combines an even (odd) number of half-integral spins the result is (half) integral spin. Conse ...

The Wilsonian Revolution in Statistical Mechanics and Quantum
... In physics as well as in many other disciplines, we are often confronted with solving problems that involve many coupled degrees of freedom. For example, let us consider the degrees of freedom involved in a block of solid. This has typically an Avogadro number (1023 ) of atoms. Each of the atoms has ...
