Flat Optics: a new approach to structured light, polarization control and lenses

Flat Optics: a new approach to structured light, polarization control and lenses (Prof. Federico Capasso)

Metasurfaces enable arbitrary control of the wavefront of light by locally manipulating polarization in addition to amplitude and phase. As a result, multiple optical functions can be encoded with greatly reduced complexity that be accessed by changing the input polarization, wavelength and k-vector. Unique ways to generate structured light, a new polarization optics that greatly surpasses the capabilities of the standard and a new class of lenses that correct aberrations without requiring multiple stacked lenses have emerged from this approach.

SDP relaxations for the certification of properties of many-body quantum states

SDP relaxations for the certification of properties of many-body quantum states (Flavio Baccari)

Understanding the properties of many-body systems is one of the crucial questions for the development of quantum technologies. An ubiquitous problem is to certify that a given many-body quantum system satisfies an operational property: is this given system in an entangled state? Does it contain the solution to a classical optimisation problem? [mehr]

The 2nd Law: History and Fiction

16923 1543914483

The 2nd Law: History and Fiction (Prof. Assa Auerbach)

The talk The 2nd Law: History and Fiction discusses the history of Maxwell’s Demon, the Second Law of Thermodynamics, and its connection to Information Theory. It shows how these concepts can be explained to non-physicists in a comic book of an adventure story called “Max the Demon vs Entropy of Doom’’. [mehr]

Entanglement in non-unitary critical spin chains

Entanglement in non-unitary critical spin chains (Romain Couvreur)

Entanglement entropy has proven invaluable to our understanding of quantum criticality. It is natural to try to extend the concept to “nonunitary quantum mechanics”, which has seen growing interest from areas as diverse as open quantum systems, noninteracting electronic disordered systems, or nonunitary conformal field theory (CFT).

Realizing Feynman’s Dream of a Quantum Simulator

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

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]
