Six new research groups on advanced materials and nanotechnologies are emerging at CEITEC

Since January 2018, four research groups have started their activities at CEITEC BUT. Two more foreign leaders will join them at the beginning of…

Spectroscopy of novel quantum emitters 

During the last years, quantum optics has received growing attention (including Nobel Prices) for its ability to tailor quantum states in a highly controlled manner. Today, quantum optical systems start to emerge from the lab and start to be ready for real world applications. In this PhD project, novel solid-state quantum emitters are researched. The main tasks this involves are fabrication, optical characterization, e.g., with single photon spectroscopy, and the understanding of the properties of these emitters.

 

Photonic structures for quantum optics  

During the last years, quantum optics has received growing attention (including Nobel Prices) for its ability to tailor quantum states in a highly controlled manner. Today, quantum optical systems start to emerge from the lab and start to be ready for real world applications. For these application it is necessary to be able to build quantum photonic elements. In this PhD project, photonic structures for such elements are designed, fabricated, and tested. For this, the underlying physics has to be understood, but also a hands-on approach in clean-room fabrication is required. 

 

Nanoassembly of quantum photonic elements  

During the last years, quantum optics has received growing attention (including Nobel Prices) for its ability to tailor quantum states in a highly controlled manner. Today, quantum optical systems start to emerge from the lab and start to be ready for real world applications. For these application it is necessary to be able to build quantum photonic elements. In this PhD project, this is done using the so-called hybrid approach, where those materials and nanoparticles are combined that can fulfil a specific task best. For this, the approach of nanoassembly is used, where either an electron microscope with manipulator an atomic force microscope is used to arrange specific configurations of nanoparticles and photonic structures. 

 

Optical investigation of nanosystems in a radio-frequency trap   

Using radio frequency traps, it is possible to study not only single ions decoupled from the environment – a technique that revolutionized physics – but also (larger) nanoparticles. Studying nanoparticles and their controlled interactions with light, electric fields, or other particles is of high interest in quantum optics and material science. In this PhD project, the student will develop the trap setup and the corresponding optical systems and thereafter use the setup to investigate the properties of nanoparticles decoupled from the environment.
