Abstract: Electrons in a conventional metal are described by Landau's celebrated theory of Fermi liquids. In the last few decades a growing number of metals have been discovered that defy a description in terms of Fermi liquid theory. Prominently, such `strange metals'  appear as parent phases out of which phenomena such as high temperature superconductivity develop.

Abstract: It is well established that people learn better when they are actively engaged with the material they are learning. In this talk, I will focus on active learning methods used in the upper division, and the research that goes into their development. In particular, we will discuss the structure of a tutorial to designed to improve student visual understanding of time dependence in quantum mechanics and the assessment of its effectiveness. We will also discuss whether or not the context of a question can impact student performance.

Abstract: Ordered plasmonic structures have been utilized for a wider range of applications. However, their properties suffer from defects, when large-scale applications are desired. There is growing evidence that the exceptional properties can be produced and tuned in disordered packings with built-in heterogeneities.

Abstract: Thermalization in open quantum systems has recently attracted attention from quantum information and quantum chaos. Today, I will first formulate thermalization in terms of Lindbladians and, as a bonus, present a quantum algorithm that efficiently emulates this process.  Second, we show fast convergence assuming the Eigenstate Thermalization Hypothesis (ETH). The talk is based on joint works with Fernando Brandao and with Andras Gilyen and Michael Kastoryano.

Abstract: The Earth’s upper atmosphere emits in the Far-UV (120 to 200nm); images at these wavelengths are indicative of the changes in, and evolution of, the lower thermosphere and ionosphere — a region critical for communication and navigation signals.  Several missions are currently available (including GOLD and TIMED/GUVI) and are planned (InspireSat/OWLS) that take advantage of the characteristics of FUV emissions to examine the neutral composition, momentum transport of gravity waves, and connection to the ionosphe

Understand the difference between stress and anxiety, while learning helpful management strategies. Mindfulness techniques will be included, as well as information about resources available on campus.

Abstract: 

Precise control of quantum states of matter and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to observe new quantum phenomena and explore fundamental physics. In this talk I will present the development of an optical atomic clock in the historical context of JILA’s science.

Abstract: Understanding emergent behaviors in strongly interacting quantum systems is a frontier area of condensed matter physics. However, simulations of quantum many-body systems on classical computers are not scalable beyond a few dozen particles. This motivates the development of quantum simulators, highly controllable analog quantum computers specifically designed to study certain types of problems in condensed matter physics.
