Johannes Pollanen

Johannes is a Jerry Cowen Chair of Experimental Physics and Assistant professor in the Department of Physics and Astronomy at MSU. Before joining the faculty at Michigan State, Johannes was an IQIM postdoctoral scholar at the Institute for Quantum Information and Matter (IQIM) at the California Institute of Technology working with Prof. Jim Eisenstein. At Caltech, he studied the exotic properties and many-body quantum states of single and bilayer 2d electron systems in ultra-clean semiconductor heterostructures grown via molecular beam epitaxy (MBE).

Johannes earned his Ph.D. in 2012 from Northwestern University where he worked with Prof. Bill Halperin in the Low Temperature Physics Group to understand the properties of complex many-particle quantum systems and engineer novel quantum mechanical forms of matter. During this time, Johannes discovered a new chiral state of superfluid 3He, which he stabilized by introducing anisotropic disorder to the superfluid in the form of high porosity silica aerogel.

Kostyantyn Nasyedkin

Kostya is working to develop novel hybrid quantum systems using the strongly correlated systems of electrons on helium. Before joining the LHQS team, Kostya was a research associate in the Quantum Condensed Phases Research Team at the RIKEN Center for Emergent Matter Science in Wako Japan. He earned his Ph.D. in physics from the B. Verkin Institute for Low Temperature Physics and Engineering in Kharkiv, Ukraine


Niyaz Beysengulov

Niyaz earned his Ph.D. in physics from the Kazan Federal University in Russia in a joint program with RIKEN (Wako, Japan). During his Ph.D. Niyaz studied two-dimensional electrons on the surface of liquid helium in micro-channel devices in the Low Temperature Physics Lab in RIKEN, where he worked with Dr. Kimitoshi Kono. There he demonstrated unprecedented control over the number of electron rows formed in microchannels and studied order-disorder phase transition in this low-dimensional electron system.

Heejun Byeon

Heejun is working to engineer novel many-body hybrid quantum systems by coupling electrons on helium to tailor-made electrostatic and electrodynamic sublattices. These coupled electronic systems are predicted to have unique and interesting transport properties and dynamics and open the door for quantum simulation experiments of strongly correlated electronic fluid and solid states of matter.

Justin Lane

Justin is studying the exotic electron phases that form in the two-dimensional material graphene. Specifically, he’s been using surface acoustic waves (SAWs) to probe these exotic phases of matter at temperatures close to absolute zero and at high magnetic fields. Additionally, Justin is developing new circuit quantum electrodynamic (cQED) experiments to study superconducting qubits and how they interact with mechanical degrees of freedom. Justin is also an accomplished marathon runner.
