1. 1. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Johanna Adbo; [2023]
   Keywords : QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

   Abstract : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. READ MORE

3. 2. Positivity of Heat Kernels

   University essay from KTH/Matematik (Avd.)

   Author : Manne Milton; [2019]
   Keywords : ;

   Abstract : Partial di˙erential equations are a well-studied field of mathematics, and in this thesis we attempt to use some of the newer methods, including path integrals (also known as Feynman path integrals) and the so-called geometric approach, to find conditions for the heat kernel of a di˙erential operator on a certain form to be zero. We also derive a maximum principle, more general than the classical one, that allows for degenerate di˙erential operators, where the degeneracy is controlled by a Muckenhoupt weight. READ MORE
