Title: Generating High-Intensity, Ultrashort Optical Pulses

Lecturer: Dr. Donna Strickland

Time: 7:00 p.m.
Date: 17 June 2024
Location: Calgary Central Library

Abstract: With the invention of lasers, the intensity of a light wave was increased by orders of magnitude over what had been achieved with a light bulb or sunlight. This much higher intensity led to new phenomena being observed, such as violet light coming out when red light went into the material. After Gérard Mourou and I developed chirped pulse amplification, also known as CPA, the intensity again increased by more than a factor of 1,000 and it once again made new types of interactions possible between light and matter. We developed a laser that could deliver short pulses of light that knocked the electrons off their atoms. This new understanding of laser-matter interactions, led to the development of new machining techniques that are used in laser eye surgery or micromachining of glass used in cell phones.

Biography: Donna Strickland is a professor in the Department of Physics and Astronomy at the University of Waterloo and is one of the recipients of the Nobel Prize in Physics 2018 for developing chirped pulse amplification with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

Strickland was a research associate at the National Research Council Canada, a physicist at Lawrence Livermore National Laboratory and a member of technical staff at Princeton University. In 1997, she joined the University of Waterloo, where her ultrafast laser group develops high-intensity laser systems for nonlinear optics investigations.

Strickland was named a Companion of the Order of Canada. She is a recipient of a Sloan Research Fellowship, a Premier’s Research Excellence Award and a Cottrell Scholar Award. Strickland served as the president of the Optical Society (OSA) in 2013. She is a fellow of OSA and SPIE, the Royal Society of Canada and the Royal Society. She is an honorary fellow of the Canadian Academy of Engineering as well as the Institute of Physics. She is an international member of the US National Academy of Science.

Strickland earned a PhD in optics from the University of Rochester and a B.Eng. from McMaster University.

Title: A Taste of Quantum: A Quantum Leap in Quantum Information

Lecturer: Peter Zoller

Time: 5-9 pm
Date: October 11, 2022
Location: Atrium, Telus Spark Science Center, Calgary

Abstract: On a microscopic scale our world is governed by quantum physics. Apart from fundamental the questions and ‘mysteries’, learning how to control this microscopic world provides exciting opportunities for new capabilities and quantum technologies—potentially more powerful than their non-quantum technology counterparts. In this public lecture, we explore recent progress in building quantum computers and quantum simulators. We’ll look at quantum optical systems in which atoms and ions are manipulated by laser light, showing how quantum systems can be controlled on the level of single quanta. From trapped ions as a universal quantum processor to digital and analog quantum simulation, we will seek to understand what harnessing the microscopic realm of quantum physics means for our society.

Title: Can we reverse-engineer the brain?

by Michael Roukes of California Institute of Tehcnology

Date: Tuesday 6 June 2017
Time: 7:00 pm
Location: Science B 103

Abstract: Although our understanding of the properties of individual neurons and their role in brain computations has advanced significantly over the past several decades, we are still far from elucidating how complex assemblies of neurons – that is, brain circuits – interact to process information. In 2011, six U.S. scientists from different disciplines banded together, outlined a vision [1,2], and managed to convince the Obama administration of the unprecedented opportunity that exists to launch a coordinated, large-scale international effort to map brain activity. This culminated in the U.S. BRAIN Initiative (Brain Research through Advancing Innovative Neurotechnologies), which was launched in 2013. Our perspective was predicated, in part, on the current level of maturity of diverse fields of nanotechnology and silicon very-large-scale integration (VLSI) that can now be coalesced to create unprecedented tools for massively parallel interrogation of brain activity. We will outline the immense complexity of such pursuits, the hopes we articulated, survey the existing technological landscape for assembling the requisite instrumentation, and then focus upon our collaborative efforts toward tools enabling multi-physical interrogation of brain activity. We believe this technology will engender a spectrum of new possibilities for neuroscience and clinical neuromedicine.

Title: A molecule takes a selfie while creating the world's shortest light pulses

by Paul Corkum
University of Ottawa

Date: Thursday 24 November 2016
Time: 7:00 pm
MacEwan Ballroom, University of Calgary

Biography: Paul Corkum started his career as a theoretical physicist but changed to experiment when he arrived as a Post doctoral Fellow at NRC in 1973. At NRC he concentrated first on laser physics but with the revolution in laser technology, intense laser pulses are now being applied in every discipline. Dr. Corkum anticipated their impact. He is best known for introducing many of the concepts in strong field atomic and molecular science. In the early 1990's a number of new, seemingly unconnected, phenomena were discovered in strong field atomic physics. Two of the most important of these are high harmonic generation and correlated double ionization (a phenomenon in which an atom absorbs 100's of photons and emits two electrons). Dr. Corkum developed a comprehensive theory of all of these phenomena. He then demonstrated its validity. This work is the foundation on which all subsequent research in this area has been built.

Canada Research Chair in Attosecond Photonics, Dr. Corkum is the Director of the Attosecond Science Program at NRC and a Professor in the Department of Physics at the University of Ottawa. Over the years, Dr. Corkum has received several distinctions in recognition of his ground-breaking research. He is a Fellow of the Royal Society of Canada (1996) and the Royal Society of London (2005) and an elected member of the US Academy of Science (2009).

Among his most prestigious prizes are the Canadian Association of Physicists' Gold Medal for Lifetime Achievement in Physics (1996), the Royal Society of Canada's Tory Award (2003), the Optical Societies Charles H. Townes Award (2005) and the IEEE's Quantum Electronics Award (2005). In 2006, he has received the Killam Prize for natural sciences, and was awarded the American Physical Society's Arthur L. Schawlow Prize for Quantum Electronics. In 2007, he was inducted as an Officer to the Order of Canada and received NSERC's prestigious Polanyi Award in 2008.

In 2013, Dr. Corkum received two very prestigious international awards, the Harvey Prize from the Technion, Israel Institute of Technology and the King Faisal International Prize for Science. The Optical Society of America (OSA) awarded him the Frederic Ives Medal in 2014 and in 2015, Dr. Corkum was named Thomson Reuters Citation Laureate, reserved for researchers who are "of Nobel class" and likely to earn the Nobel someday.

Since the early days of quantum mechanics, and still in Feynman's lectures on physics, interference between spatially separated trajectories of a single particle has not ceased to fascinate physicists. I will present a realization in optics of that GedankenExperiment, realized with a true single photon source. It has even allowed us to implement Wheeler's delayed choice experiment, emphasizing the weirdness of wave particle duality for a single particle.

Alain Aspect is an internationally acclaimed physicist at the École Polytechnique in Paris. He is a pioneer in the foundations of quantum physics, including celebrated demonstrations of quantum non-locality (sometimes referred to as Einstein's spooky action at a distance). He received the 2010 Wolf Prize in Physics, which is one of the world's top science awards. In addition to his beautiful, convincing experiments, Dr. Aspect is famous for the clarity and general appeal of his presentations.
