Ultrafast Microscopy of Spin-Momentum Locked Surface Plasmon Polaritons

The recently published paper in journal of ACS NANO on Ultrafast Microscopy of Spin-Momentum Locked Surface Plasmon Polaritons is an essential research for designing optical elements to control spin-polarized SPP (surface plasmon polaritons) fields on the nano femto scale. Hrvoje Petek and his colleagues have shown two-photon photoemission electron microscopy images formed by coupling and propagation of longitudinal and transverse components of SPP fields of light. Further, they have also shown the spin-momentum locked SPP wave packets launched with circularly polarized excitation propagate at the same phase and group velocities as for the linearly polarized excitation using time-resolved experiments.

Qi Li has received the Bright Futures Student Award from the International Precious Metals Institute for his work on gold nanoparticles. The $5,000 prize sponsored by the Gero Family Trust will be presented this month at the institute's annual conference in Texas.

Li, who works in the lab of Rongchao Jin, also has researched different models of "doping" gold nanoparticles, a process where a small amount of another metal is added to the nanoparticle.

Mukund Bapna received the 2018 Guy C. Berry Graduate Student Research Award. He was presented with the prize at the Mellon College of Science Graduate Student Town Hall in April.

He was working under the supervision of Sara Majetich on magnetic tunnel junction nanopillars, nanostructures. 

Bapna received his Ph.D. in May and is now heading off to Portland, Oregon, to work for the research and development team at Intel.

There he will be developing smart interconnects for nodes under 20 nanometers in size for next-generation processors.

Topological Protection of Photonic Mid-Gap Defect Modes

Kevin Chen and his colleagues have demonstrated in a proof-of-concept experiment that they can contain light in such a way that makes it highly insensitive to defects that might be present in a material.

"From the perspective of photonic engineers, this is a wonderful learning opportunity to see the connections between lightwave engineering at length scale of micrometers, and quantum mechanics that typically deals with electron waves at length scale 10,000 times smaller," noted Kevin P. Chen.

PQI Faculty Attended Intel ISEF 2018 Public Day

PQI faculty Geoffrey Hutchison, Sangyeop Lee, and David Pekker represented PQI on Intel ISEF 2018 Public Day.

Intel ISEF Public Day is an outreach program where middle and high school students from Pennsylvania (grades 6-12) participates in a hands-on, interactive day celebrating science.

Geoffery Hutchison had a booth at this event where he showed how to visualize chemistry by using computational methods via smartphone technology.

Sangyeop Lee presented the concept of waste heat recovery in a workshop.

David Pekker gave a lecture on quantum computers.

Lilian Chong, the founder of Pitt’s Creative Science Writing Program, is leading a program on science and creativity along with Pitt English Instructor and award-winning poet, Sam Pittman.

In this program, they bring students from Chemistry and English together.

While she was demonstrating a simulation of molecules students work on poems describing molecular level emotions. 

Bradley Slezak Received His Ph.D. Degree

Bradley Slezak was a graduate student under the supervision of Wolfgang J. Choyke and Brian D'Urso.

This spring he has successfully passed his Ph.D. defense. On Thursday, April 26, 2018 he attended the commencement ceremony at the John M. and Gertrude E. Petersen Events Center to receive his degree.

His research involved measuring the decoherence rate of non-classical states of the trapped particle.

Congratulations Dr. Bradley Slezak !
