    • Observation of Astrophysical Neutrinos by IceCube 

      Taboada, Ignacio (Georgia Institute of Technology, 2013-09-16)
      Even though cosmic rays were discovered more than 100 years ago, their origin remains a mystery. Neutrinos, product of cosmic ray interactions at or near the production site, are the best astrophysical messenger to find ...
    • Observing the signature of a single prolific r-process event in an ultra-faint dwarf galaxy 

      Frebel, Anna (Georgia Institute of Technology, 2017-10-23)
      The heaviest chemical elements in the periodic table are synthesized through the rapid neutron-capture (r-) process but the astrophysical site where r-process nucleosynthesis occurs is still unknown. The best candidate ...
    • Opportunities Created by Spin-Orbit Interactions 

      Cao, Gang (Georgia Institute of Technology, 2022-04-04)
      Effects of spin-orbit interactions in condensed matter are an important and rapidly evolving topic. A sea change occurred with the discovery of spin-orbit interactions in graphene by Mele and Kane, which has led to the ...
    • Optical Lattice Clocks: From Timekeepers to Spies of the Quantum Realm 

      Rey, Ana Maria (Georgia Institute of Technology, 2022-03-28)
      Harnessing the behavior of complex systems is at the heart of quantum technologies. Precisely engineered ultracold gases are emerging as a powerful tool for this task. In this talk I will explain how ultracold strontium ...
    • Optical Metamaterials: From Linear Responses to Nonlinear Interactions and Beyond 

      Cai, Wenshan (Georgia Institute of Technology, 2014-10-06)
      Metamaterials are commonly viewed as artificially-structured media capable of realizing arbitrary effective parameters, in which metals and dielectrics are delicately combined to facilitate the index contrast and plasmonic ...
    • Optically-Trapped Interacting Fermi Gases 

      Thomas, John E. (Georgia Institute of Technology, 2021-09-13)
      Optically-trapped, ultra-cold gases of spin ½-up and spin ½-down 6Li atoms enable “designer” interactions, offering a versatile environment for simulating exotic quantum systems that span a vast range of energy. A strongly ...
    • Origins of Structure in Inner Planetary System 

      Murray-Clay, Ruth (Georgia Institute of Technology, 2021-03-01)
      Why do many stars host close-in chains of super-Earths? Why are eccentric gas giants found in some inner planetary systems? What determines which of these outcomes will occur around a particular star? I will present a ...
    • The Physics of How Viruses Make New Viruses 

      Phillips, Rob (Georgia Institute of Technology, 2012-03-12)
      The viruses that infect bacteria have a hallowed position in the development of modern biology, and once inspired Max Delbruck refer to them as "the atom of biology". Recently, these viruses have become the subject of ...
    • Physics of Morphogenetic Matter 

      Gardel, Margaret (Georgia Institute of Technology, 2021-11-08)
      My lab studies how the movement and shape of living cells is controlled by living materials constructed by protein assemblies within the cell interior. In this talk, I will describe my lab’s recent efforts to understand ...
    • Physics of the Piano 

      Giordano, Nick (Georgia Institute of Technology, 2012-10-01)
      Why does a piano sound like a piano? A similar question can be asked of virtually all musical instruments. A particular note, such as middle C, can be produced by a piano, a violin, and a clarinet. Yet, it is easy for even ...
    • Protecting the Space Environment: Sustainability and Security 

      Borowitz, Mariel (Georgia Institute of Technology, 2022-03-07)
      In recent years, the number of objects in space has grown rapidly, and this growth is projected to continue to accelerate over the next decade. There has also been increased military activity in space, including rendezvous ...
    • Protein Association in Dilute and Crowded Solutions 

      Zhou, Huan-Xiang (Georgia Institute of Technology, 2011-11-09)
      Most biological processes are mediated by mediated by protein association, and often are under kinetic rather than thermodynamic control. We have developed the transient-complex theory for protein association, which presents ...
    • Quantum Crystals, Quantum Computing, Quantum Cognition 

      Fisher, Matthew (Georgia Institute of Technology, 2015-10-05)
      Quantum mechanics is down to earth - quite literally - since the electrons within the tiny crystals found in a handful of dirt manifest a dizzying world of quantum motion. Each crystal has it’s own unique choreography, ...
    • Quantum FM Radio for Quantum Computing 

      Schuster, David (Georgia Institute of Technology, 2017-03-27)
      Individual superconducting qubits have seen impressive improvements in nearly all aspects over the past decade and now sit at the threshold of being able to perform quantum error correction. Scaling to larger numbers of ...
    • Quantum Magnetism from the Iron Age to Today 

      Arovas, Daniel (Georgia Institute of Technology, 2021-04-12)
      The quantum theory of magnetism has provided many durable paradigms for quantum phases of matter, including intrinsically quantum disordered states, symmetry-protected topological phases, and quantum spin liquids. It also ...
    • Recipe for a Habitable Planet 

      Shields, Aomawa L. (Georgia Institute of Technology, 2020-09-21)
      The discovery of numerous small exoplanets has brought the search for life beyond the Solar System into sharp focus on many potentially habitable worlds where life may exist. However, many factors and processes can affect ...
