Two QSIT PIs have received two of the coveted Advanced Grants in the European Research Council's (ERC) latest call for proposals. For both scientists, this is their second such grant.

Tilman Esslinger is Professor of Quantum Optics at ETH Zurich. In his new project, he is examining elementary transport mechanisms in a system that obeys the laws of quantum physics.

Frédéric Merkt, Professor of Physical Chemistry, will use his ERC project to explore chemical reactions of charged atoms and molecules (ions) with molecules at extremely low temperatures, paying particular attention to quantum-physical effects.

ERC Consolidator Grant to Giacomo Scalari: Scalari’s research addresses “frequency combs”, which act as rulers in the frequency domain and can measure the frequency of electromagnetic radiation – including light – very precisely. Scalari will use his ERC Consolidator Grant to create on-chip, self-referenced frequency combs operating in the THz spectral range, where there is currently no compact comb source available. These devices will be appealing for metrology and material inspection, non-invasive imaging for medical applications, and wireless communication.

The Quantum Optics group of Tilman Esslinger in close collaboration with theorists from College de France, Ecole Polytechnique, CNRS, University of Geneva and University of Bonn explored for the first time thermoelectric effects in an ultracold Fermi gas.

The setup is in close analogy to a mesoscopic solid state device where two leads prepared at different temperatures are connected to a conducting channel, which generates current from the thermoelectric effect.

The cold atom emulation of a solid state device shines new light on thermoelectricity: comparison between theory and experiments, which are often hard for natural materials due to their high complexity, can now be precisely performed with cold atoms. Even the effects of defects and disorder in materials have been successfully explored in their work, which has been published in the journal Science.

Andreas Kuhlmann working in Richard Warburton’s group, in collaboration with Martino Poggio and researchers at the Ruhr-Universität Bochum, has found a way to identify and quantify charge noise and spin noise in a semiconductor quantum device. This understanding has allowed the group to achieve transform-limited quantum dot optical linewidths, required to create indistinguishable single photons. Their work has been published in the journal Nature Physics.

First Report of Real-Time Manipulation and Control of Nuclear Spin Noise: Physicists from Martino Poggio's group, in collaboration with researchers at the Eindhoven and Delft Universities of Technology, have demonstrated a new method for polarizing nuclear spins in extremely small samples. The scheme may provide a route for enhancing the sensitivity of nanometer-scale magnetic resonance imaging (MRI) or possibly for the implementation of solid-state quantum computers. The researchers have published their work in the journal Nature Physics.

Andreas Nunnenkamp, a postdoc in Christoph Bruder's group, is part of an international team of researchers identifying signatures of the intrinsic nonlinear interaction between light and mechanical motion in cavity optomechanical systems. These signatures are observable even when the cavity linewidth exceeds the optomechanical coupling rate. They are nonlinear variants of optomechanically induced transparency and should be observable with optomechanical coupling strengths that have already been realized in experiments.

Researchers look beyond space and time to cope with quantum theory

Physicists around Nicolas Gisin have proposed an experiment that could force us to make a choice between an extreme and the unknown to describe the behavior of the Universe. 

The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a ‘hidden influence inequality’. This exposes how quantum predictions challenge our best understanding about the nature of space and time, Einstein’s theory of relativity.

These new findings help to selectively control and manipulate electron spins in electronic devices. Spintronics could enable a new class of magnetic-based semiconductor transistors resulting in more energy efficient electronic devices.
