Seminars

On an irregular basis various Special Seminars take place at the MPQ. The seminars are organized by scientists of our divisions, administration or staff representatives.

The location will be announced with the event.

Month:

Strong-field dynamics of molecules: electron-nuclear correlation

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

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. [more]

New quantum SI units and fundamental constants

New quantum SI units and fundamental constants (Dr. Savely Karshenboim)

The International system of units, SI, has just been changed once again. The new definitions, which concern the kilogram, ampere, kelvin, and mole, are to come in force on May, 20. Similarly to the definition of the metre in terms of the speed of light, those four units are now defined in the terms of exact adopted values of fundamental constants, such as the elementary charge, Planck, Boltzmann, and Avogadro constants.

Physics and applications of epsilon-near-zero materials

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

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. [more]

Spatial entanglement patterns and Einstein-Podolsky-Rosen steering in a Bose-Einstein condensate

Spatial entanglement patterns and Einstein-Podolsky-Rosen steering in a Bose-Einstein condensate (Dr. Matteo Fadel)

Atomic Bose-Einstein condensates (BECs) are highly controllable isolated quantum systems with long coherence times, and offer applications in metrology and quantum information processing. We experimentally prepare two-component Rubidium-87 BECs, consisting of a few hundred atoms, on an atom-chip. Using state-selective potentials to tune the collisional interactions (one-axis twisting dynamics), we prepare many-particle non-classical states. After a time-of-flight expansion, high-resolution images allows us to access sub-regions of the atomic density distribution of various shapes and measure the spin correlations between them. [more]

Laser Spectroscopy with Extreme Resolution

Theodore Maiman Series: Laser Spectroscopy with Extreme Resolution (Prof. Dr. Nirgitta Bernhardt)

This talk is devoted to modern methods of laser spectroscopy, with the special focus on applications that require extreme ultraviolet (XUV) radiation and extreme resolution. [more]
