New Directions in Galaxy Formation and Cosmology Following the First High-z 21-cm DetectionOn March 1st, the EDGES collaboration reported the detection of a sharp absorption signal in the all-sky radio spectrum at ~80 MHz. This frequency is roughly consistent with early theoretical predictions for the global 21-cm signal, a sky-averaged spectral signature of neutral hydrogen atoms in the intergalactic medium before cosmic ...

Neutrino Torquing We show how galaxy spin alignment directly measures the initial tidal field, thus doubling the information content of galaxy surveys. The initial density field can be recovered to $ksim 1$ using spin alignment and non-linear galaxy displacement reconstruction, separately. By measuring two scalar fields, we measure the gravitational field of ...
Increased demands of high energy density, long lasting batteries, low cost and safe batteries for applications in consumer electronics, electric vehicle and grid with renewable energy integration present great opportunities and challenges to the society. This seminar will review the status of existing battery technology and present the challenges, opportunities ...
'Nature in the City' MapThe program will begin with an introduction to the map and a pop-up exhibit. The Nature in the City map may just be the first of its kind. A collaboration among artists, scientists, mapmakers, and more, it seeks to express the built world of San Francisco within the larger, older, unfolding, ...

Revolutionary Materials Path for Computing beyond CMOS TransistorsComputing is at a momentous point as devices approach the 10 nm dimensions even as new breakthrough AI/QC architectures evolve. In this talk, I will outline the framework that combines the energy/dimension scaling (Moore’s law), computer error rates (Shannon computing) and modern AI architectures. I also outline how the next ...
People and Robots SeminarThe promise of driverless vehicles to transform the urban mobility experience is contingent on them behaving well within the human driving and pedestrian ecosystem. Driverless vehicles must behave in a socially acceptable manner. This talk will unpack what this means and explore how the technologies for achieving this.Speaker: Liam Pedersen, ...

Sketching Big DataA "sketch" is a data structure supporting some pre-specified set of queries and updates to a database while consuming space substantially (often exponentially) less than the information theoretic minimum required to store everything seen, and thus can also be seen as some form of functional compression. The advantages of sketching ...

THE PHYSICS OF 2-D MATERIALSDr. Jairo Velasco of UC Santa Cruz, a recent recipient of the NSF CAREER Award, presents his research on the characterization and control of Dirac fermions within nanoscale p-n junctions.
Digitalization, data sets, computing, technology, analytics are all rapidly advancing. Our energy analytics approach and collective tool kit of models and capabilities has advanced considerably over the past decades. Today, we are at yet another precipice of change, with exponential increases in data availability, advanced analytics (including AI/ML/NNs), and scalable ...

Toy Models‛Toys’ here have a special sense: objects from daily life which you can find or make in minutes, yet which, if played with imaginatively, reveal behaviors that puzzle good physicists for a while. (In particular, if you can buy one from a toy store, it's almost certainly not a ‛toy’ ...

Light of the Stars: Alien Worlds and the Fate of the EarthOur Earth is just one of ten billion trillion planets in the Universe. Using the latest science, in this talk we'll see that we’re likely not the first time a technological civilization has emerged from planetary evolution. More important, all those other worlds and other possibilities have a lesson to ...

How Do We Become “Robot Proof” in Our Professional Lives? How Will AI Put Humanity Back to Work?In this talk, Vivienne Ming will address the challenge that technology is changing faster than culture, and many of the jobs available today will soon be radically de-professionalized by automation and AI. How can society adapt to this change? How do professionals maintain their value in this ever-developing technological climate?Speaker: ...
