MPL Distinguished Lecturer Series

Controlling and Exploring Quantum Matter

Time: 3 pm

Place: MPL / large seminar room (*435)

Title: Controlling and Exploring Quantum Matter

Speaker: Prof. Immanuel Bloch (Max Planck Institute of Quantum Optics/LMU Munich)

Abstract:

Over the past years, ultracold quantum gases in optical lattices have offered remarkable opportunities to investigate static and dynamic properties of strongly correlated bosonic or fermionic quantum many-body systems. In this talk, I will show how it has recently not only become possible to image such quantum gases with single atom sensitivity and single site resolution, but also how it is now possible to coherently control single atoms on individual lattice sites. I will demonstrate how 'Higgs' type excitations occur at 24 orders of magnitude lower energy scales than in high energy experiments and how they can detected in our experimental setting. Finally, I will present a new method to realize artificial gauge fields for ultracold atoms and show a novel method how to measure the Berry-Zak phase of topological band-structures using ultracold atoms.

MPL Distinguished Lecturer Series

Plasmonics - From Quantum Effects to Fano Interference and Light Harvesting

Time: 3 pm

Place: MPL / large seminar room (*435)

Title: Plasmonics - From Quantum Effects to Fano Interference and Light Harvesting

Speaker: Prof. Peter Nordlander (Rice University)

Abstract:

The "plasmon hybridization" paradigm shows that the plasmon resonances in complex metallic nanostructures interact and hybridize in a manner analogous to how atomic orbitals interact and form collective states in molecules.[1] The insight gained from this concept provides an important conceptual foundation for the development of new plasmonic structures that can serve as substrates for surface enhanced spectroscopies, chemical and biomolecular sensing, and subwavelength passive and active optical devices.[2] The talk is comprised of general overview material interspersed with more specialized "hot topics" such as plasmonic radiative coherence and interference effects,[3] quantum plasmonics[4], quantum plexcitonics,[5] active plasmonic nanoantennas for enhanced light harvesting,[6] and plasmon induced chemical reactions.[7]

IMPRS get-together (Kopie 23)

Place: large seminar room / MPL

Organisation: Federico Belli (MPL, Russell Division)

Talk: The angular momentum of light

Speaker: Prof. Andrea Aiello (MPL)

Abstract:

Every student knows that massive spinning objects, like a bicycle wheel, possess an angular momentum directed along the axis of rotation. Perhaps fewer students know that also non-massive physical systems, as light, may exhibit an angular momentum which becomes manifest when light interacts with matter. In this talk I will present a general survey of angular momentum of light mainly focusing on its historical development. In addition, I will illustrate some examples of relevant practical and fundamental applications of this fascinating and timely subject.

MPL Distinguished Lecturer Series

Femtosecond Optics: More Than Just Really Fast

Time: 3 pm

Place: MPL / large seminar room (*435)

Title: Femtosecond Optics: More Than Just Really Fast

Speaker: Prof. Erich P. Ippen (Massachusetts Institute of Technology)

Abstract:

Advances in femtosecond lasers that are making it possible to generate pulses with durations on the order of one optical cycle are also providing the capabilities for better clocks, coherent broadband frequency combs, attosecond timing synchronization and precision sampling for improved analog-to digital signal conversion. By spatially separating and rapidly modulating many individual comb frequencies, truly arbitrary optical-frequency electric-field waveforms can be generated. This talk will describe recent progress toward these goals based on Ti:sapphire and fiber laser technologies to cover the wavelength range of 500nm - 2µm.

MPL Distinguished Lecturer Series

Dressing Molecules and Materials with the Vacuum Field

Time: 3 pm

Place: MPL / large seminar room (*435)

Title: Dressing Molecules and Materials with the Vacuum Field

Speaker: Prof. Thomas W. Ebbesen (University of Strasbourg)

Abstract:

Strong coupling of light and matter can give rise to a multitude of exciting physical effects through the formation of hybrid states. Organic molecules have been increasingly used for the study of strong coupling since their large transition dipole moment permits the observation of vacuum Rabi splitting in the range of hundreds of meV at room temperature. Such large modifications in the energy levels have significant implications for molecular and material sciences as well as physics. After introducing the fundamentals of strong coupling, our recent research on this topic will be presented.
