Seminare

In unregelmäßigen Abständen finden am MPQ Seminare statt. Diese werden von den Wissenschaftlern der einzelnen Abteilungen organisiert.

Der Veranstaltungsort wird mit dem jeweiligen Seminar bekannt gegeben.

Ort: Max Planck Institute of Quantum Optics

The Optical Society (OSA)

OSA presents its actions and programs for the “optics and photonics” community: students, faculty and industry from all over the world. Benefits will be shown for those relating with OSA at various levels, including the journal publishing program, including reviewer policies and rewarding. On demand, a more in depth description of student chapters will be given, its setup, the benefits (not only to students) and how to maintain and develop it. Everybody is welcome (OSA members and non-members). [mehr]

Certification of Quantum Measurements and New Entangled Quantum Probes

Certification of Quantum Measurements and New Entangled Quantum Probes
In the quantum information literature, self-testing refers to the action of uniquely determining a quantum state based solely on the statistics of measurement outcomes and minimal assumptions. These quantum self-testing protocols are more stringent than well-known Bell tests. While violation of a Bell inequality for a bipartite system establishes that its quantum state is entangled, it cannot certify, for instance, that its quantum state is maximally entangled. We extend self-testing techniques to certification of quantum measurements in various physical settings. [mehr]

Fundamental science by high-power microwaves - Millimeter-wave spectroscopy of positronium hyperfine structure and further ( Prof. Dr. Akira Miyazaki)

Fundamental science by high-power microwaves - Millimeter-wave spectroscopy of positronium hyperfine structure and further
The microwave technology has been one of the important tools in fundamental physics since Rabi's pioneering work on hydrogen atoms. In this seminar, direct spectroscopy of positronium hyperfine structure with very high frequency microwaves, often referred to as millimeter or sub-THz waves, will be discussed. [mehr]

Strong-field dynamics of molecules: electron-nuclear correlation (Prof. Jian Wu)

Strong-field dynamics of molecules: electron-nuclear correlation
The primary phase of the light-molecule interaction is the photon energy absorption and deposition. Although the electron is much lighter than the nuclei, there is a strong electron-nuclear correlation for molecules exposed to strong laser fields. The photon energy deposits into the nuclei governs the succeeding dynamics and thus the fate of the molecules. [mehr]

Theodore Maiman Series: Physics and applications of epsilon-near-zero materials (Prof. Dr. Robert Boyd)

Physics and applications of epsilon-near-zero materials
In this talk, we describe some of the unusual optical properties of materials, known as epsilon-near-zero (ENZ) materials, for which the dielectric permittivity is very small. We describe some of the unusual geometrical optical properties of such materials and present theoretical predictions of how fundamental radiative properties are modified under such conditions. We also describe some of the nonlinear optical properties of these materials. Recent work has shown that optical materials can display an extremely large optical nonlinear response in their ENZ spectral region. [mehr]
