Position Openings

(1) Laser-Induced Electron Diffraction and Quantum Dynamics

A post-doctoral researcher position is presently available to join the Attoscience and Ultrafast Optics group at the Institute of Photonic Science (ICFO). The position is dedicated to quantum dynamics, specifically the attosecond imaging of molecular dynamics based on laser induced electron diffraction (LIED). The research draws from a unique few-cycle and CEP-stable high-repetition rate mid-IR source (2-6 cycle pulses, 160 kHz, 0.5 PW/cm2, 3200 nm) in combination with a reaction microscope (COLTRIMS) which permits kinematically complete investigations in the deep tunneling regime. Experimental will build on our recent investigations of i) atomic recollision dynamics [1], ii) nonaligned and aligned molecular species, towards iii) attosecond self-diffraction imaging of bond breaking and proton motion. The research will be carried out in the framework of collaborative research and with prominent theory groups. The success of this project will have significance in fields of attoscience, molecular imaging, and atomic/molecular physics with clear potential for high profile scientific output.

Environment: Our friendly and stimulating environment includes state of the art laboratories with several unique and cutting edge few-cycle and tunable light sources ranging from the soft X-ray to the mid-infrared. Supporting infrastructure includes facilities for material growth, preparation and diagnostics. We are embedded in several prominent national, European and international networks as well as collaborations which ensures a vibrant and stimulating international research environment.

Position: We offer a postdoctoral position to a highly motivated scientist who wishes to enhance his/her scientific career in an emerging new field which resides at the forefront of attosecond science, structural imaging and ultrafast dynamics. The candidate will conduct experimental research within our existing teams on the mid-IR driven LIED beamline. The position is available immediately and initially offered for one year with the possibility for extension.

Qualification: We are seeking an enthusiastic candidate with background in electron or x-ray diffraction, attoscience or ultrafast physics. We expect diligent work ethics, clear command of English, interest in cross disciplinary work and an aptitude for problem solving and team work. The candidate must hold a Ph.D. degree (or evidence of its completion in the nearest future). No restrictions of citizenship or gender apply to the position.

Contact: Candidates should forward a CV and references to jens.biegert@icfo.eu.

PhD position in Quantum Dynamics

“Attosecond molecular structure”

Dynamic imaging of molecular structure is a core area of science since a “molecular movie” would provide revolutionary insight into the connection between molecular structure at critical transition points and barrier heights. These parameters determine whether and how a molecule changes its conformation or dissociates, and how a chemical reaction or protein folding proceeds. Clearly, understanding structural dynamics precludes understanding function and, hence, the structure function relationship is an important fundamental concept in the molecular sciences.

The PhD project will be concerned with attosecond electron dynamics and the imaging of molecular structure of complex molecules. The project will be based on our recent development of Mid-IR Laser Induced Electron Diffraction  [1,2] and the first real-space, real-time imaging of bond breaking and proton motion [3].

Position: We offer a PhD fellowship position to a highly motivated candidate who wishes to enhance his/her scientific career in the field of Attosecond Science and Strong Field Physics. The position in our team is available immediately and we will provide a stimulating environment to perform research on the cutting edge of both science and technology.

Qualification: We are seeking an enthusiastic candidate with background ideally related to atomic physics, attoscience, or ultrafast lasers. Experience with femtosecond pulses, electron spectroscopy, AMO physics or vacuum equipment are highly desired, but not required. A successful candidate will have a background in experimental physics or a related field. No restrictions of citizenship or gender apply to the position.
