Comparison of excitation methods for frequency conversion in rubidium (JTu2A.1)

Lightwave Topology for Strong-field Valleytronics (FTu3B.2)
Presenter: Alvaro Jimenez-Galan, Max Born Institute

Modern light generation technology offers extraordinary capabilities for sculpting light pulses, with full control over individual electric field oscillations within each laser cycle. These capabilities are at the core of lightwave electronics -- the dream of ultrafast lightwave control over electron dynamics in solids, on a few-cycle to sub-cycle timescale, aiming at information processing at tera-Hertz to peta-Hertz rates. At the same time, quantum materials have opened the way to dissipationless electron transport and to the possibility to harness extra electronic degrees of freedom, such as the valley pseudospin, that can be used as additional information carriers. In this talk, I will show a robust and general approach to control and probe the topological properties of 2D quantum materials by controlling the sub-cycle structure of non-resonant driving fields at a few-femtosecond timescale. I will show that this control permits non-resonant excitation, manipulation and reading of valley-polarized electrons in 2D materials on timescales orders of magnitude shorter than valley lifetime, crucial for practical implementation of valleytronic devices.

Nonlinear Lattice Dynamics Driven by Intense Terahertz Pulses (STu4G.1)
Presenter: Matthias Hoffmann, SLAC National Accelerator Laboratory

Intense Terahertz (THz) pulses offer a unique way to manipulate matter on a sub-picosecond timescale. Their strong electric and magnetic field components efficiently couple to low-energy degrees of freedom like optical phonons or magnons while we can simultaneously use ultrafast probe techniques to monitor changes in the sample with femtosecond resolution. This allows us to study novel nonequilibrium phases and the response of matter to strong transient fields.
Matthias Hoffmann is staff scientist at LCLS, the world’s first hard x-ray free electron laser.
He has spent most of hiscareer in ultrafast laser science, primarily on terahertz generation and spectroscopy. After graduating from the University of Freiburg in Germany, he joined Keith Nelson‘s group at MIT as a postdoc where he worked with Janos Hebling to implement the first high energy THz sources based on the tilted pulse front technique in lithium niobate.
In 2009 he moved to Hamburg, Germany and worked as a scientist in Andrea Cavalleri’s group at CFEL and continued his work on nonlinear THz spectroscopy, exploring light-induced superconductivity in high temperature superconductors.
After two years in Andrea’s group he accepted a position as staff scientist at LCLS. His main responsibilities here are the development of improved THz sources and the support of user experiments using these sources at LCLS. In the last few years, he had many fruitful collaborations with researchers from all over the world and demonstrating some of the first THz-pump x-ray probe experiments.
In his free time he enjoys spending time with his family and road cycling on the beautiful roads of northern California.

Frequency-Domain Quantum Interference with Entangled Photons from an Integrated Microresonator (FTu4C.6)
Presenter: Chaitali Joshi, Cornell University

We report frequency-domain quantum interference with spectrally distinct photons from a microresonator. We create an active, tunable ‘frequency beam splitter’ via Bragg-scattering four-wave mixing and achieve interference visibilities of 0.95 ±0.02.

Two photon interference via coupled ring resonators on a silicon photonic chip (FTu4C.7)
Presenter: John Serafini, Rochester Institute of Technology

We demonstrate an on-chip Hong-Ou-Mandel (HOM) experiment where the conventional directional coupler-based beam splitter is replaced with coupled ring resonators. Two photon interference is achieved with raw visibilities as high as 95% and, ~π rotation is achieved.
