Multi-electron correlation spectroscopy of atoms and molecules
... Correlated many-particle dynamics in Coulombic systems is one of today‟s grand challenges in physics. In order to address this task, the electronic structure and electron correlations of multiply ionised systems are studied in this thesis, aiming to obtain information on the dynamics of electron emi ...

Concrete analysis of Regev`s worst-case to average
... In this note, the tightness gap of a reduction algorithm from problem A to problem B is the number of calls to the oracle for B that are made by the reduction algorithm. Regev’s worst-case/average-case reduction has two main components: (1) The reduction of (search-)LWE to average-case DLWE (denoted ...

Chapter 3. Foundations of Quantum Theory II
... An axiom of quantum theory asserts that a measurement may be described as an orthogonal projection operator. But if a measurement of system S is realized by performing an orthogonal measurement on a larger system that contains S, the resulting operation performed on S alone need not be an orthogonal ...

Spin-Orbit-Mediated Anisotropic Spin Interaction in Interacting Electron Systems

We then conclude that the leading source of spin anisotropy is provided by the vdW contribution (11) and (13), which does not contain an exponential smallness of the exchange.

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
