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]

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

New quantum SI units and fundamental constants
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.

Quantum light-matter interfaces that reversibly map photonic quantum states onto atomic states, are essential components in the quantum engineering toolbox with applications in quantum communication, computing, and quantum-enabled sensing. [mehr]

Doped resonating valence bond states: a quantum information study (Dr. S. Singha)

Resonating valence bond states have played a crucial role in the description of exotic phases in strongly correlated systems, especially in the realm of Mott insulators and the associated highTc superconducting phase transition. [mehr]

Detection of Zak phases and topological invariants in a chiral quantum walk of twisted photons (Dr. A. Dauphin)

Initially discovered in condensed matter, topological phases have so far been simulated in a variety of synthetic systems (ultracold atoms in optical lattices, photonic bandgap materials, mechanical systems, ...). [mehr]
