A warm welcome goes out to our four new CCQ postdocs; Fan Yang, Juan Sánchez-Baena, Ragheed Alhyder, and Shanshan Ding, who have been joining our research team during the winter.

If you have not already read their introductory profile, here is the chance to read them once again.

Fan Yang, 

In December 2020, Fan joined CCQ and the research group of Klaus Mølmer. At present, he is working in the theoretical field of quantum optics and quantum information processing, and in particular with a main interest in Rydberg atom systems. Fan obtained his PhD degree in August 2020, at the Department of Physics, Tsinghua University, where he afterwards continued to work as a research associate.

In January 2021, we had the pleasure of welcoming both Ragheed Alhyder and Juan Sánchez-Baena to the center.

Ragheed Alhyder, 

Ragheed graduated his masters in quantum physics at École Normale Supérieure in Paris followed by a PhD in the group of ultracold Fermi gases at Laboratoire Kastler Brossel at École Normale Supérieure led by Christophe Salomon. During his PhD he contributed to the construction of a new-generation cold atoms machine with the goal of studying unitary ultracold fermions.

Ragheed also carried on theoretical studies regarding the physics of an impurity immersed in a two-component fermi gas. For instance, one goal was to explore the different phases manifested by this system depending on the interaction between the impurity and fermions from the bath.

Ragheed defended his PhD in December 2020 and at CCQ he will be conducting theoretical research with professor Georg Bruun on subjects related to atom-light interaction, topological phases and ultracold bosons and fermions.

Juan Sánchez-Baena, 

Juan obtained his Msc. Degree in Advanced Physics in 2016, in Barcelona's University. He moved afterwards to Prof. Jordi Boronat's group, at the Polytechnic University of Catalonia, to start his PhD in Computational and Applied Physics under the supervision of Prof. Jordi Boronat and Prof. Ferran Mazzanti.

He successfully completed his PhD studies in December 2020. His PhD research revolved around the design and application of quantum monte carlo methods for the study of spin-orbit coupling systems, together with the characterization of these systems by means of non-monte carlo approaches such as beyond mean field calculations at the Bogoliubov level.

In Thomas Pohls group, Juan will be working on ultracold quantum gases, with focus on polaron and polariton systems.

Lastly, Shanshan Ding joined CCQ in February 2021, where she will be conducting theoretical research with Professor Georg Bruun.

Shanshan Ding, 

Shanshan obtained her PhD degree from the University of Hong Kong in 2017 and for the last three years, she has been working as a postdoc in the research group led by Dr Shizhong Zhang. Her main research interests are the degenerate quantum gases and the strongly correlated system.

The grand tour awaits,

Due to the current COVID19 situation, unfortunately, the Department of Physics is still closed for all staff members and so the grand tour at the sixth floor awaits, along with a key to their offices. We all look forward to meeting our new colleagues in the nearest future.
