Quantum mechanics and path integrals

2015
Abstract This chapter discusses the Feymann path-integral approach to quantum mechanics. First, it derives a path integral expression for the evolution operator. Next, it shows that the classical equations of motion, that is, those obtained from the principle of least action, are obtained from this path integral formulation in the limit ...

Path Integrals in Relativistic Quantum Mechanics

1994
This paper is a review of path integral representations for semigroups {exp(-t H_r/ħ)}{t≥0} where H_r's are relativistic quantum Hamiltonians. We consider three different cases: in the first one Hr is a relativistic Schrödinger operator, in the second is the Hamiltonian associated to Klein-Gordon equation and in the third is that coming from the Dirac

Path integrals in quantum mechanics

2011
Path integrals provide in many instances an elegant complementary description of quantum mechanics and also for the quantization of fields, which we will study from a canonical point of view in Chapter ?? and following chapters. Path integrals are particularly popular in scattering theory, because the techniques of path integration were originally ...

Quantum Mechanical Path Integrals

2010
The fundamental equation of quantum mechanics for a single particle is generally taken to be a Schrodinger equation of the form $$i\hbar\frac{\partial}{\partial t}\psi(x, t) =\left[-\frac{{\hbar}^{2}}{2m} \frac{{\partial}^{2}}{{\partial}{x}^{2}}+{V (x, t)}\right] \psi(x, t),$$ subject to some initial condition such as $$\lim_{t \rightarrow t^
