Building quantum network nodes based on neutral silicon vacancy centers in diamond
Wed, Jul 28, 2021, 1:30 pmColor centers in diamond are attractive candidates for implementing single-atom quantum memories in a quantum network. This thesis describes an approach to build quantum networks nodes based on color centers in diamond. We propose to use a novel single-atom quantum memory, the neutral charge state of silicon vacancy (SiV0), as the building block for future quantum network. The unique combination of long spin coherence times and efficient optical transitions makes SiV0 a promising candidate for such application.
Multipoles, symmetry representations and thermal fluctuations in elastic systems
Thu, Jul 15, 2021, 3:00 pm to 5:00 pmIn recent years, we have seen exciting new developments in research on mechanical metamaterials, topological phononics, and mechanics of atomically thin 2D materials. In this talk, I present how methods from physics can help us in understanding the mechanical properties of these systems as well as gaining further intuition.
Neural Network Learning: A Multiscale-Entropy and Self-Similarity Approach
Fri, Jul 16, 2021, 8:30 am to 10:30 amNeural networks are machine learning models whose original design has been vaguely inspired by the structure networks of neurons in human brains. Due to recent technological advances that have enabled fast computations on larger models and more training data, neural networks have found many applications in a growing number of areas of science such as computer vision, natural language processing, and medical imaging.

Software Design for Modeling Quantum Cascade Laser and Long Wavelength (∼16 μm) GaAs/AlGaAs Quantum Cascade Lasers
Thu, May 20, 2021, 2:00 pm to 3:30 pmAbstract:
We review the modeling techniques for mid-infrared quantum cascade lasers based on III/V materials, clarifies or corrects ambiguity concepts such as state-dependent effective mass, the non-parabolic kinetic energy and its modeling, and the polarized waveguide confinement in the mathematical perturbation sense.
