38. Characterization of magnetic structures using (coherent) x-rays

Andreas Scholl (Lawrence Berkeley Lab)

Condensed matter applications

I will lead in by giving a brief overview over the Advanced Light Source and over techniques that may be of interest to the QIS and in particular the quantum materials community. I will then discuss two examples: Photoemission Electrion Microscopy (PEEM), which was used to study the ground state and thermal dynamics of artificial spin ice systems and soft x-ray interferometry, which we used to...

39. Spontaneous spin-chain fluctuation observed with coherent x-ray scattering

Condensed matter applications

As we explore new materials harboring entangled quantum states, an efficient probe for their detection is necessary. Coherent x-rays are a direct probe for equilibrium and nonequilibrium dynamics that can simultaneously measure a large number of particles. In my talk, I will use our recent work on dipolar-coupled artificial spin lattices (ASL) and explore the possible route to use coherent...

26. Valley-Mechanical Coupling in a Monolayer Semiconductor

Mr Haokun Li (University of California, Berkeley)

Condensed matter applications

The interaction of macroscopic mechanical object with electron charge and spin plays a vital role in today’s information technology and fundamental studies of the quantum-classical boundary. Recently emerged valleytronics encodes information to the valley degree-of-freedom and promises exciting applications in communication and computation. We realize valley-mechanical coupling in a monolayer...
