The study of strongly correlated electronic systems and the development of quantum transport in nanoelectronic devices have followed distinct, mostly non-overlapping paths.  Electronic correlations of complex materials lead to emergent properties such as superconductivity, magnetism, and Mott insulator phases. Nanoelectronics generally starts with far simpler materials (e.g., carbon-based or semiconductors) and derives functionality from doping and spatial confinement to two or fewer spatial dimensions.  In the last decade,...

There is considerable interest today in quantum materials. While all materials obey quantum mechanics, there is specific interest in phenomena that go beyond the independent single electron approximation, and arise in strongly correlated electron systems, strong spin-orbit coupled systems, and topologically protected systems. In this talk, I will present an interesting state of matter called polar metals in a correlated electron system, Ca3Ru2O7. The talk will present the origin of the counterintuitive polar displacements in a bulk metal, and show that it has domains and...

As we begin to look at how spin qubits might be integrated into a scalable platform, a fruitful strategy is to engineer the magnetic environment of the spins using micron- or nanometer-scale ferromagnetic (FM) elements, for functionalities such as nanoscale addressability, spin-wave mediated coupling, or enhanced sensing. The promise of these FM/spin interactions brings with it the question of how the coherence properties of the spin will be affected by coupling to these complex mesoscopic systems. To explore the physics of individual spins coupled to a proximal, dynamic...

The last decade has seen the rapid growth of interest in materials that are topological because of strong spin-orbit coupling. These samples exhibit electronic surface states that have only half the electrons that a carrier accumulation layer has. The surface states have energy between the occupied valence band and the unoccupied conduction band and the energy/momentum dispersion is linear forming two so-called Dirac cones that meet at the Dirac point, often k=0. They exhibit spin-momentum locking so that a surface state with momentum in some direction has spin...

Introduction: In the halls of Congress there is widespread agreement about the role of R&D in the success of the America’s most innovative corporations. However, too often lawmakers view government models of discovery, from NASA to public university research labs, as obsolete and costly superstructures in today’s .com marketplace. What happened to the case for public exploration and discovery and why shouldn’t the private sector be trusted to find the cure for Grandma’s dementia or Johnny’s brain tumor? Long-time Washington political insider, former lobbyist, Administration appointee, and AIMBE’s Executive Director, Milan Yager, will reveal the hidden truth about why Congress doesn’t fund needed biomedical research.

Results and Discussion: This presentation will highlight innovations and achievements made possible from past federal investments in basic research; such as the internet, wireless communications, even mapping the human genome. Today, Congress seems less interested in past accomplishments as they assume new priorities to balance the budget, reduce government, and free the private sector to assume long-standing government responsibilities for innovation and discovery. How did Congress make spending decisions to permit federal R&D spending to be flat for over a decade? Learn about why Congress is no long accountable for reduce investments in basic research. Discover three secrets to making a winning case for federal funding for medical and biological research. Learn practical steps to successfully getting your point across to a Member of Congress. Find out how to brand your research as the Sputnik in the race to cure cancer, manage chronic disease, or Type I diabetes.

Conclusions: Arming yourself with the strategies for the political warfare in the case for innovation is more than just changing public policy; it can provide the key to changing the future landscape of new biomedical materials, products or procedures. Attendees will get insight into America’s next biomedical “moonshot” initiative.
