    • Arch and scaffold: Hilbert space and transformation theory 

      Janssen, Michel (Georgia Institute of Technology, 2018-04-02)
      In early 1927, Paul Dirac and Pascual Jordan, independently of one another, published their versions of a general formalism tying the various forms of the new quantum theory together and giving the theory’s statistical ...
    • The Astrophysics of Black Hole Spin 

      Reynolds , Chris (Georgia Institute of Technology, 2013-04-22)
      In addition to providing vital clues as to the formation and evolution of black holes, the spin of black holes may be an important energy source in the Universe. Over the past couple of years, tremendous progress has been ...
    • Autonomous Motility in Soft Active Matter 

      Dogic, Zvonimir (Georgia Institute of Technology, 2015-04-06)
      The laws of equilibrium statistical mechanics impose severe constraints on the properties of conventional materials assembled from inanimate building blocks. Consequently, such materials cannot exhibit spontaneous motion ...

      Shifman reviews the growth of quantum physics from its inception in the beginning of the 20th century to its maturity 50 years later. His narrative includes dramatic stories of the quantum pioneers between two wars. Caught ...
    • The Biggest Little Molecules in Nature 

      Greene, Chris H. (Georgia Institute of Technology, 2011-12-07)
      This colloquium will discuss recent theoretical predictions and experimental confirmation of two unusual classes of ultra-long-range molecules. One class involves a highly-excited Rydberg electron that manages to bind a ...
    • Building a Cell from the Bottom Up 

      Ross, Jennifer (Georgia Institute of Technology, 2015-11-09)
      Biology utilizes energy to organize itself from the nanoscale to the macroscopic scale. We seek to determine the universal principles of organization from the molecular scale that give rise to architecture on the cellular ...
    • Cell Mechanics: The Active Polymer Networks Underlying Force Transmission in Living Cells 

      Gardel, Margaret (Georgia Institute of Technology, 2012-04-16)
      Many different types of biological cells have the capability of sensing and generating mechanical forces. These biophysical properties of cells are utilized for many different aspects of cell physiology, including cell ...
    • Collapse of the Collapse: Physicists Return to Reality 

      Daw, Murray S. (Georgia Institute of Technology, 2021-10-18)
      Recent developments[1] have shown that the collapse hypothesis is self-inconsistent and is no longer a viable theory. (The collapse hypothesis in quantum mechanics is that the state of a system is collapsed by a measurement, ...
    • Compact Penning Traps for Quantum Science with Cold Atomic Ions 

      Sawyer, Brian C. (Georgia Institute of Technology, 2022-04-11)
      Penning ion traps are useful experimental platforms for quantum simulation, mass spectrometry, precision metrology, and molecular ion spectroscopy. The GTRI Quantum Systems Division (QSD) has developed a compact, ...
    • Computation with Quanta 

      Amini, Jason M. (Georgia Institute of Technology, 2013-02-11)
      A quantum processor, using quantum states of light and matter, holds the promise of performing calculations and simulations that are not practical by a classical processor. Many of the key components for a quantum processor ...
    • Consider the Icicle 

      Morris, Stephen (Georgia Institute of Technology, 2013-02-04)
      Icicles are harmless and picturesque winter phenomena, at least in cold climates. The shape of an icicle emerges from a subtle feedback between ice formation, which is controlled by the release of latent heat, and the flow ...
    • Cosmic Information Theory and Analysis: IT from BIT, from BITs in IT 

      Bond, J. Richard (Georgia Institute of Technology, 2011-11-30)
      We consider the Universe to be fundamentally quantum and statistical, the many-paths/many-worlds story. This lecture uses Cosmic Information Theory and Analysis, CITA, as a unifying theme to explore the vast sweep of our ...
    • Course Reform MIT Style: Student Evaluations vs. Scientific Evidence 

      Pritchard, David E. (Georgia Institute of Technology, 2017-04-03)
      The evaluation of most course reforms typically rests heavily on teacher and student evaluations; I’ll argue that this is unwise. In contrast, I’ll discuss course reform MIT style: select objectives, adopt metrics, experiment, ...
    • Crackdown on Academic Collaboration with China Harms American Science 

      Xi, Xiaoxing (Georgia Institute of Technology, 2021-11-01)
