IMPRS-APS: Realizing Feynman’s Dream of a Quantum Simulator (Prof. Immanuel Bloch)

Realizing Feynman’s Dream of a Quantum Simulator
More than 30 years ago, Richard Feynman outlined his vision of a quantum simulator for carrying out complex calculations on physical problems. Today, his dream is a reality in laboratories around the world. [mehr]

IMPRS-APS Talk: Ultrafast electron control: from the particle accelerator on a chip to attosecond charge transfer in a Schottky junction (Prof. Dr. Hommelhoff)

Ultrafast electron control: from the particle accelerator on a chip to attosecond charge transfer in a Schottky junction
Firstly, I will deal with a new way of accelerating charged particles based on femtosecond laser pulses and nanophotonic structures. The concept is exactly the same as in classical RF and microwave accelerators, only with roughly five orders of magnitude faster oscillating driving fields and structures that are smaller by the same factor. With the help of such small lithographically produced dielectric structures we have demonstrated not only efficient acceleration of electrons, but also deflection and focusing. Currently, we are building a prototype "accelerator on a chip". The current status will be reported. [mehr]
The new idea consists in exploiting the optical field itself to control the properties of crystals and nanostructures. With this approach, it becomes possible to access phenomena occurring within an oscillation of light as benchmarked by three experiments. [mehr]

IMPRS-APS Monthly Talk/ Solids in Ultrafast Strong Fields: Topological Attosecond Phenomena (Prof. Mark Stockmann)

We present our latest results for a new class of quantum phenomena in condensed matter nanooptics when a strong, single-oscillation optical field ∼1 V/Å induces changes in a solid, which are defined by its topological properties. [mehr]
