From Quantum Confinement to Quantum Electrodynamics using nanoCathodoluminescence in a STEM
Cathodoluminescence (CL) has been used for decades to study luminescence of semi-conductors and presents obvious advantages with respect to Photoluminescence. This includes an easy access to high energies (UV regions and above), which is competitive for e.g high band gap materials study, or a strong absorption cross-section, interesting e. g. for the detection of diluted defects. Of course, an ...
متن کاملExistence of Confinement Phase in Quantum Electrodynamics
We show that the four-dimensional U(1) gauge theory in the continuum formulation has a confining phase (exhibiting area law of the Wilson loop) in the strong coupling region above a critical coupling gc. This result is obtained by taking into account topological non-trivial sectors in U(1) gauge theory. The derivation is based on the reformulation of gauge theory as a deformation of a topologic...
متن کاملCalculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics
In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

متن کاملDynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
