Dissipative engineering of cold atomic systems

Dissipative engineering of cold atomic systems (Dr. Jorge Yago)

Cold atom systems in optical lattices provide a promising platform for a wide variety of applications, ranging from quantum simulation to quantum metrology, due to their extremely high tunability and the ability to derive microscopic models under well-controlled approximations that give access to accurate descriptions. The proper characterization of those systems requires, in many scenarios, taking into account that they are subject to some dissipation sources, as dissipation can drastically modify the behaviour of the known phases of matter or even generate new ones. However, the description of open systems can quickly become numerically unaffordable. [mehr]

Experimental tests of quantum non-locality beyond EPR-steering and beyond Bell

Experimental tests of quantum non-locality beyond EPR-steering and beyond Bell (Prof. Howard Wiseman)

In this talk I will present an unpublished theory and experiment for two quantum nonlocality scenarios which generalise EPR-steering and Bell, respectively. in the sense of having weaker assumptions and thus more stringent experimental conditions. The first is to allow a finite amount of FTL communication of classical information in an EPR-steering scenario. The second relates to the recent theorem of Bruckner using "Wigner friends" in place of the determinism assumption in some formulations of Bell's theorem. [mehr]

An effective description of Ramsey tunnel-coupled 1D Bose gases with the Pokrovsky-Talapov model

An effective description of Ramsey tunnel-coupled 1D Bose gases with the Pokrovsky-Talapov model (Valentin Kasper)

The high flexibility of ultracold atoms allows for the design, control and thorough investigation of quantum matter. In this work we consider two one-dimensional Ramsey tunnel-coupled Bose gases and elaborate on its relation to the Prokrovsky-Talapov model. Further, we study the ground state with variational wave-functions and explore the experimental relevant finite system size effects. Finally, we discuss possible quench protocols in order to study the non-equilibrium evolution of the Pokrovsky-Talapov model and predict experimental relevant quantities such as the phase and the density.

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.
