Temperature is intensity of heat present in a substance or object, especially as
expressed according to a comparative scale. It is also referred to as the average amount of
kinetic energy. Thermodynamics is the study of heat and work. It relates energy tr

Observables and Propagators
In earlier chapters we have considered the properties of a number of field
theories that describe physical systems isolated from the outside world. However, the only way to investigate the properties of a physical system is

Path Integrals in Quantum Mechanics and
Quantum Field Theory
In the past chapter we gave a summary of the Hilbert space picture of
Quantum Mechanics and of Quantum Field Theory for the case of a free
relativistic scalar fields. Here we will present the

Quantization of Gauge Fields
We will now turn to the problem of the quantization of gauge theories. We
will begin with the simplest gauge theory, the free electromagnetic field.
This is an abelian gauge theory. After that we will discuss at length the

Canonical Quantization
We will now begin the discussion of our main subject of interest: the role
of quantum mechanical fluctuations in systems with infinitely many degrees
of freedom. We will begin with a brief overview of quantum mechanics of a

Classical Symmetries and Conservation Laws
We have used the existence of symmetries in a physical system as a guiding
principle for the construction of their Lagrangians and energy functionals.
We will show now that these symmetries imply the existence

Classical Field Theory
In what follows we will consider rather general field theories. The only guiding principles that we will use in constructing these theories are (a) symmetries and (b) a generalized Least Action Principle.

Non-Relativistic Field Theory
In this Chapter we will discuss the field theory description of non-relativistic
systems. The material that we will be presented here is, for the most part,
introductory as this topic is covered in depth in many specialized
