857. From Nonlinear Optics to High-Intensity Laser Physics

Prof. Donna Strickland (University of Waterloo)

12/12/2022, 09:00

Plenary

Invited talk

The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction that is referred to as high-intensity laser physics. In this talk, I...

858. Quantum sensing and imaging with diamond spins

Prof. Ania Bleszynski Jayich (University of California, Santa Barbara)

12/12/2022, 09:45

Plenary

Invited talk

The diamond NV center offers a uniquely versatile path towards nanoscale imaging of condensed matter and biological systems. Here I present NV-based magnetic imaging experiments and discuss challenges to improved resolution and sensitivity, largely focused on materials engineering and tackling interface-induced decoherence.

859. Silicon Photonic Quantum Computing – Towards Large-scale Systems

Prof. Jeremy O'Brien (University of Western Australia and PsiQuantum)

13/12/2022, 09:00

Plenary

Invited talk

Many efforts around the world are now pursuing the ambitious goal of utility-scale, fault-tolerant quantum computing. Consistent themes are emerging across the field, as teams attempt to scale from existing small systems to the millions of qubits needed for useful applications. Systems partitioning, manufacturability, cooling power, networking, and control electronics are recurring challenges...

860. From Quantum in Pictures to practical Natural Language Processing, Music, and understandable AI

Prof. Bob Coecke (Quantinuum Ltd.)

13/12/2022, 09:45

Plenary

Invited talk

This talk requires no particular technical mathematics background, as I will talk entirely in terms of simple pictures. These are the pictures of my new book, "Quantum in Pictures" [1], which is aimed at the teenage enthusiast, and pretty much everyone else too - the book had a more technical predecessor [2].

One finds the same pictures in natural language, and much of the high-level...

846. Neutron stars and gravitational waves in the context of modern nuclear physics theory

Prof. Jirina Stone (University of Oxford/University of Tennesse)

14/12/2022, 09:45

Plenary

Invited talk

Neutron stars,the densest known objects, form a rich laboratory for testing nuclear theories trying to describe the nuclear force. I will outline current approaches and their ability to impact the interpretation of gravitational waves arising from binary neutron star collisions.

862. Educational Transformation at a Critical Time: The essential roles and promise of physicists

Prof. Noah Finkelstein (University of Colorado, Boulder)

15/12/2022, 09:00

Plenary

Invited talk

Significant, perhaps unprecedented, attention is being paid to the needs for transformation within the fields of science, technology, engineering, and mathematics (STEM) education at the undergraduate level. This talk examines how higher education STEM disciplines, and physicists and physics departments in particular, are positioned to contribute to these discussions and address our...

861. The Coming Decade of Gravitational wave detection and astronomy

Prof. Rana Adhikari (Caltech)

15/12/2022, 09:45

Plenary

Invited talk

The LIGO-Virgo-KAGRA network has detected approximately 100 merging compact objects using gravitational wave detection. The next series of upgrades promises increasing our understanding of highly warped spacetime, nuclear astrophysics, and cosmology. To reach those astrophysical targets, the measurements will have to be improved through quantum metrology, advances in thin film materials, and...

864. Applications of nanophotonics — from bright colours to nanometrology and energy conversion

Stefan A. Maier (Monash University)

16/12/2022, 11:00

Plenary

Invited talk

Structuring materials below the wavelength scale provides a means for light harvesting to nanometric dimensions. Particularly suitable are metallic nanostructures due to the existence of highly confined surface plasmon excitations, which allow efficient harvesting of electromagnetic energy and its transduction to other forms, for example acoustic surface waves or the supply of energy to...

865. Where Next in the Search for Dark Matter?

Tracy Slatyer

16/12/2022, 11:45

Plenary

Invited talk

The nature of dark matter is an outstanding puzzle of fundamental physics. I will describe current limits on the broad space of viable dark matter scenarios, and outline some exciting directions for dark matter searches over the next decade, covering both terrestrial experiments and searches based on astrophysical observations.

863. The Dark Energy of Quantum Materials

Prof. Laura Greene (Florida State University)

Plenary

Invited talk

The many correlated electron problems remain largely unsolved after decades; with one stunning success being BCS electron-phonon mediated conventional superconductivity. The Cooper pairing mechanisms of the dozens of families of unconventional superconductors, including the high-Tc cuprate, iron-based, and heavy fermion superconductors remain elusive and quite varied. But some of their...
