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:

Fundamental science by high-power microwaves - Millimeter-wave spectroscopy of positronium hyperfine structure and further

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

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. [more]

Direct laser cooling to Bose-Einstein condensation

Direct laser cooling to Bose-Einstein condensation (Alban Urvory)

Laser cooling methods are virtually ubiquitous for the production of ultracold quantum gases. Yet in order to reach quantum degeneracy, a complementary step of lossy and inefficient evaporative cooling has so far been required (with few specific exceptions). [more]

Nuclear-driven Electronic Coherences in Polyatomic Molecules

Nuclear-driven Electronic Coherences in Polyatomic Molecules

Electronic coherences in molecules has emerged as a ‘grand challenge’ in molecular sciences due to the role that electronic correlations and dynamics play in structure and bonding. In the field of attosecond science, electronic coherences can be prepared by attosecond pulses, producing purely electronic wavepackets which persist while the atoms are ‘frozen’ (i.e. a few femtoseconds). Once the atoms unavoidably start to move, the wavepacket could dephase and the electronic coherence would be lost. However, some suggested that nuclear motion could modify or even induce electronic coherences. [more]

Large deviations and cMPS in open quantum dynamics

Large deviations and cMPS in open quantum dynamics

In this talk I will describe a perspective on the dynamics of Markovian open quantum systems based on the study of the statistical properties of ensembles of quantum trajectories. This "thermodynamics of quantum trajectories" approach is to dynamics what the standard equilibrium configuration ensemble method is for statics. [more]

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]
