"Control of Collective Quantum Phenomena in Metal-Oxide Superlattices"

Correlated electrons exhibit a fascinating variety of ordering phenomena including high-temperature superconductivity and unconventional magnetism. A grand challenge in this field is the transition from conceptual understanding of collective phenomena to their control and design. We will discuss recent results of an experimental program designed to meet this challenge through the synthesis and characterization of metal-oxide superlattices. We will show how polarized photon-based methods such as resonant x-ray scattering and Raman scattering can be used to obtain a comprehensive description of the electron system in these systems, outline perspectives for control of the phase behavior of correlated electrons by modifying the occupation of transition metal d-orbitals, the dimensionality of the electron system, and the electron-phonon interaction.

"The First Five Years of the Alpha Magnetic Spectrometer on the International Space Station: Unlocking the Secrets of the Cosmos"

AMS is a precision, large acceptance, multipurpose particle physics detector on the Space Station.  In five years, it has collected more than 90 billion primordial cosmic rays with energies up to the multi-TeV range. To date, the results show unique and unexpected features of cosmic rays.  The AMS results do not agree with existing cosmic ray models.  The precision of the results requires a new and comprehensive understanding of cosmic rays.

"Does the Future of Fundamental Physics Lie in the Sky?"

Our understanding of the constituents of our universe and the laws that bind them, has grown in leaps and bounds over the last century. Nonetheless, concordance cosmology confronts us with the reality that 95% of the energy density of the universe is poorly understood, at best. In this talk we will explore what is known about our universe and discuss some modest ideas for how to push the bounds of our knowledge. 

In particular, I will review chameleon gravity and its predictions.  I will discuss how we can go about testing chameleons and present the experimental bounds to date as well as prospective future observations and bounds. Having taken this foray through chameleons as an exemplar of how valuable varied probes of our theories are, we will finally shift our focus to the immense potential of radio astronomy for probing fundamental physics and general relativity.

"New Views of the Universe"

I will discuss how progress in cosmology over the past decade has improved our understanding of dark matter, dark energy, and the physics of the early universe. I will particularly concentrate on the developments in mapping out the expansion rate of the universe and the growth of density fluctuations in order to better understand dark energy, and eventually identify the physics responsible for universe's accelerated expansion.

"Nuclear Physics as Precision Science"

Theoretical Nuclear Physics has entered a new era. Using the powerful machinery of chiral effective Lagrangians, the forces between two, three and four nucleons can now be calculated with unprecedented precision and with reliable uncertainties. Furthermore, Monte Carlo methods can be adopted to serve as a new and powerful approach to precisely solve nuclear structure and reactions. I will discuss the foundations of these new methods and provide a variety of intriguing examples. Variations of the fundamental constants of Nature can also be investigated and the consequences for the element generation in the Big Bang and in stars are considered. This sheds new light on our anthropic view of the Universe.
