Visiting Researcher in Gedik Group at MIT

posted May 25, 2016, 6:08 AM by Guy Marcus

Beginning in July 2016, I will have the pleasure of visiting Nuh Gedik's research group at the Massachusetts Institute of Technology in Cambridge, MA for a full year. The lab specializes in the development of advanced optical spectroscopies and their application to quantum materials. In particular, they are a leader in time-resolved techniques including trARPES with one-of-a-kind high-harmonic-generation for incident-energy photons as high as 50eV in a lab-based laser setup. 

I look forward to all we may learn about the magnetism of (nominally) itinerant electrons through the combination of access to electronic excitations via photon based spectroscopies and to magnetic excitations via continued neutron scattering!

Come check out my talk on the insulating skyrmion compound Cu2OSeO3 this Thursday, March 17th (details below). I will discuss some of our extensive neutron scattering experiments focusing on the low energy magnon dispersion and present newly resolved features which await theoretical explanation.

Quantum Matter---changing the world?

Or changed the world? I recently talked with Hilary Bruek, contributor to Forbes Magazine, about the role quantum matter plays in our daily lives and why it keeps me coming into work everyday. You can check out our conversation here:

Forbes 30 Under 30 Summit: Israel

Following the composition of the Forbes 30 Under 30 in Science and other categories, the Forbes Summit Group hosts a conference with attendees culled from awardees, mentors, and relevant public figures. In addition to the standard conference, this year is the first international conference to be hosted in Israel. 

If you will also be at the 2016 Forbes Under 30 Summit: Israel and would like to connect, please feel free to reach out!

Invited talk: Connecting exotic magnetism with electronic bandstructure

posted Dec 6, 2015, 5:52 PM by Guy Marcus

I will be visiting MIT this Tuesday to deliver a talk for the Gedik Group about my ongoing work using neutron scattering to disentangle complex magnetic structures. CeAuSb2 represents a common thread of magnetic metals on the verge between localized and itinerant behavior. Careful materials design and advanced experimental techniques enable this rich environment for realizing unique quantum states of matter which test our fundamental understanding of what role the Fermi surface topology plays in stabilizing magnetism.

Our recent paper in the New Journal of Physics has been chosen as a 'Highlight of 2014'.

To see related work under active development, you may visit the homepage of the Prof. Greg Voth's lab at Wesleyan University.

CeAuSb2 at the 2015 APS March Meeting

posted Feb 26, 2015, 6:44 PM by Guy Marcus

Come check out my talk at the APS March Meeting on Wednesday March 4th, 2015 during session Q22 at 4:30 PM in Room 202A. I will discuss recent results of neutron diffraction experiments on CeAuSb2. We have found long wavelength modulated magnetism and the zero field phase and present an ANNNI model that can stabilize the observed structure for a range of exchanges. A manuscript is forthcoming!

Measurements of the solid-body rotation of anisotropic particles in 3D turbulence

posted Oct 13, 2014, 4:55 PM by Guy Marcus

Check out my latest article that was just published as a Fast Track Communication in New Journal of Physics. We designed and fabricated millimeter scale anisotropic particles using 3D printing and measured their rotational dynamics using novel experimental techniques. Apart from a fundamental understanding of particle dynamics, this provides an accurate and convenient method for measuring Lagrangian vorticity.

I will be at the APS March Meeting in Denver this week. My talk is in session M40 at 1:03 PM on Wednesday. You can view my slides by following the link.

"Understanding the Chain Fountain"

posted Feb 26, 2014, 4:17 AM by Guy Marcus

I've written my first piece for OZY.com, a fresh news site that aims to bring you only the most exciting stories with a unique spin. I will contribute pieces from time to time as an independent science consultant. My first popular article is an account of the recent paper published in the Royal Proceedings that should be suitable for the layperson. It explains the video below:
