Title: A New Generation of Millimeter and Submillimeter Observations for Cosmology and Astrophysics Abstract: In our exciting era of experimental cosmology, rapid developments in instrumentation and highly sensitive superconducting detectors have provided a wealth of arcminute-scale cosmic microwave background (CMB) data. These measurements are transforming our understanding of the evolution of our cosmos. I will…
Speaker:Â Anton Malko Title:Â Heralded Photons and Stimulated Emission Using Colloidal Semiconductor Quantum Shells Abstract:Â Spherically shaped semiconductor nanoplatelets, called quantum shells (QSs) have recently attracted considerable attention as they exhibit strongly suppressed Auger recombination, ultralong biexciton (BX) lifetimes and broad gain bandwidth. However, no applications that demonstrate true lasing action using QSs in optical cavity configurations have…
Title: Topological Stars and Gravity Abstract: In this colloquium, I will discuss aspects of microscopic degrees of freedom of gravity and the physical motivation of quantum gravity. While the generic states are quantum mechanical, our goal will be to understand a class of them that are coherent enough to admit classical descriptions in Einstein gravity.…
Title: Flow, Fluctuate and Freeze: Modeling Collective Cell Motion Using Soft Active Matter Abstract: Active or living materials are made out of agents that can move on their own, such as birds, fish, or artificial systems such as robots or active colloids. Cells are a core active material, and the two-dimensional tissues known as epithelial…
