2283. Waveform control for attoscience in condensed matter (I)

Dr TJ Hammond (University of Ottawa)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier(ère) invité(e)

We create and control intense transient waveforms by compressing in space and time optical pulses down to a single half-cycle, nearly 1 femtosecond (1 fs = ${10}^{-15}$ s) in duration. By measuring the optical waveform using an in-situ attosecond (1 as = ${10}^{-18}$ s) technique we confirm the pulse reshaping. We use the intense transient as a source for generating isolated attosecond pulses...

2321. Attosecond-Resolved Soft X-Ray Excitonics (I)

Dr Julien B. Bertrand (Laval University)

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Invited Speaker / Conférencier(ère) invité(e)

Attosecond Physics explores ways to follow and control matter with unprecedented temporal resolution (1 attosecond= 10-18 s.). Strong laser fields used to apply forces on the sub-cycle timescale, together with the availability of tabletop attosecond soft x-ray pulses, now open avenues for time-resolving ultrafast dynamics on the unexplored attosecond timescale [1, 2]. In this first attosecond...

2175. Simultaneous Adiabatic Rapid Passage in Multiple Quantum Dots (G)

Oral (Graduate Student) / Orale (Étudiant(e) du 2e ou 3e cycle)

The initialization and control of the quantum states of excitons in semiconductor quantum dots (QDs) may be achieved using coherent optical pulses, making these systems of interest for solid state approaches to quantum simulators [1] and single photon sources [2]. Quantum state control via adiabatic rapid passage (ARP), which is insensitive to variations in the QD parameters (dipole moment,...
