Monte and Usha Ahuja Distinguished Lecture Series @ E001 Scott Labs
Sep 14 @ 3:00 pm – 4:00 pm

Speaker: Reza Abhari, Ph.D.

Affiliation: ETH Zurich

Title: TBD

Details coming soon.


The Monte and Usha Ahuja Distinguished Lecture Series aims to attract highly accomplished and illustrious individuals, as well as those on their way to national and international renown. In addition to showcasing the work of current experts in the engineering field, this lecture series will inspire Ohio State students to achieve excellence and eminence in their own future careers in government, industry and academia.

Physics Colloquium: Nitin Samarth @ 1080 Physics Research Building (Smith Seminar Room)
Sep 25 @ 3:45 pm – 4:45 pm
We provide a perspective on the recent emergence of “topological spintronics,” which relies on helical Dirac electrons on the surfaces of solids with strong spin-orbit coupling [1]..When timereversal symmetry is broken by ferromagnetic order, the helical Dirac states transition to chiral edge states [2]. This is a realization of Haldane’s Chern insulator phase of matter, characterized by a precisely quantized Hall conductance and ballistic edge transport without a magnetic field, even in systems with significant electronic and magnetic disorder [3,4]. The interplay between these edge states, dissipative channels and magnetic order appears to yield a condensed matter realization of quantum tunneling out of a ‘false vacuum’ [4]. Interesting opportunities are also emerging for patterning and manipulating the edge states using optical techniques [5]. On a more pragmatic note, the helical spin texture of the surface states also leads to efficient spincharge conversion at room temperature [6,7], allowing one to envision novel devices for universal memory and spin-based logic.

HackOHI/O @ Ohio Union
Oct 27 @ 8:00 am – Oct 28 @ 5:00 pm

*Final event times have not been set.


The Ohio State University’s largest hackathon, HackOHI/O, is a weekend event focused on building and creating real projects. More than 750 undergraduate and graduate students will design, build and demonstrate software to a live audience of students, faculty and representatives from tech companies.


Participants will meet other passionate, fun and creative students from Ohio State and universities across the nation. Industry partners are also sending professional developers, designers, marketers and hustlers to provide mentorship.


Held in the Ohio Union, the hackathon is organized by OHI/O, a student-led organization that aims to build and foster the tech community at Ohio State .
