31. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications
Sammanfattning : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. LÄS MER
32. Quest for quantum signatures in Axion Dark Matter and Gravity
Sammanfattning : This licentiate thesis in theoretical physics focuses on the existence of quantum features in physical systems such as axion dark matter and gravity. Our focus is mostly on effects which appear at low energies, a regime in which our models can be confronted with current experiments or within the foreseeable future. LÄS MER
33. Thermoelectric phenomena in low-dimensional semiconductor systems
Sammanfattning : This thesis investigates thermoelectric effects, predominantly in low-dimensional semiconductors. Various novel phenomena are predicted, investigated and discussed. LÄS MER
34. QED and collective effects in vacuum and plasmas
Sammanfattning : The theory of quantum electrodynamics (QED) was born out of an attempt to merge Einsteins theory of special relativity and quantum mechanics. Einsteins energy/mass equivalence together with Heisenberg's uncertainty principle allows for particle pairs to be spontaneously created and annihilated in vacuum. LÄS MER
35. Development and Application of a First Principle Molecular Model for Solvent Effects
Sammanfattning : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. LÄS MER
