Experimental Studies of 24Mg States and Their Impact on Nucleosynthesis in Globular Clusters
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…
Photothermal heating with nanoparticles: enhancing electrical conductivity in composites and water vapor formation in hydrogels
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: Understanding the emergence of microbial collective behaviors Abstract: Groups of cells of all kinds work together as part of multicellular behaviors ranging from collective migration to development. These behaviors are coordinated at the level of single cells, where information about other cells and the environment are encoded in intracellular signaling dynamics that then drive…
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: Self-consistent predictions of nucleosynthesis and kilonovae from compact binary mergers Abstract: Understanding the details of r-process nucleosynthesis in binary neutron star mergers (BNSM) ejecta is key to interpreting kilonova observations and identifying the role of BNSMs in the origin of heavy elements. I will present a new tool to self-consistently study, in a two-dimensional,…
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…
