Postdoctoral Scholars

Matthias Gohlke

During my PhD in the group of Roderich Moessner at MPI for the Physics of Complex Systems in Dresden/Germany I studied lattice systems with competing interactions. In particular, I learned to apply tensor network techniques to two-dimensional spin systems like Kitaev's Honeycomb model. More generally, my research interests include novel phases of matter exhibiting fractionalization, topological states, anyons, emergent gauge fields, etc.., but also computational techniques like tensor networks. I'm looking forward to spend my free time on exploring Okinawa and Japan.

Geet Rakala

During the course of my PhD with Prof. Kedar Damle at the Tata Institute of Fundamental Research, I studied 2-dimensional lattice models of frustrated magnets using Monte-Carlo techniques. I recently got interested in water and at OIST, I am looking at deploying the numerical skills that I developed during my PhD to study the hydrogen bond network of water.  Apart from work, I have a strong interest in mastering various Unix tools like bash and vim. On the physical side of things, I like to keep it light by playing amateur table tennis once a month on average. In Okinawa, I hope to explore the culture and cuisine of this stunning island and learn a little Japanese while I am at it.

Tokuro Shimokawa

After I got my PhD at the University of Hyogo, I worked as a postdoc at the Kobe (2012-2013) and Osaka (2013-2017) Universities, Japan. I've been interested in the novel magnetic states observed in frustrated spin systems, especially now, I'm studying on spin liquid and multiple-q states by means of some numerical techniques. I'm really happy to be able to study physics with many wonderful, respectable researchers. In my spare time, not only physics, I will enjoy playing tennis, diving and drinking with my friends, coworkers and family in this beautiful island.

PhD Students

Soshi Mizutani

After finishing my MS thesis on cuprate superconductors in the supervision of Catherine Kallin at McMaster/KITP, I came back to Japan, after 5 years in freezing cold North America, to start my PhD program here on this beautiful tropical island. I am interested in physics of strongly correlated systems in general. In my spare time, I participate in various OIST sports clubs including soccer, basketball, badminton etc to let my steam off, and I also enjoy playing piano and sanshin to unwind.

Kimberly Remund

As past of my Master’s degree, which I did at EPFL in Switzerland, I had the opportunity to accomplish my Master’s project here at OIST. After what I decided to join the OIST PhD program and the TQM unit.
Beside physics and science, I like dancing, cycling along the hilly, winding roads of Okinawa and enjoying the pleasant weather as well as the tasty food of the Islands. I am also interested in Martial Arts and in discovering more about the history and culture of Okinawa.

Andreas Thomasen

I graduated from Aarhus University with a master's degree in optics and electronics. I've since then done various short research projects in quantum state engineering and cold atom physics. Eventually I have found myself at OIST, where I am now doing my PhD in the Theory of Quantum Matter unit. I enjoy learning about strange states of matter that exist at very low temperatures and the methods that are used to describe them. I find the intuitions that one can obtain here very satisfying and elegant. I also like rowing, cycling and playing esoteric board games with my friends.

Han Yan- JSPS Fellow

After obtaining a Master degree of Applied Math from Univ. of Cambridge and another of Physics from Northwestern Univ., I started my PhD program at OIST, where I have been exposed to various fascinating problems in both condensed matter and high energy physics. I work on the boundary of these two disciplines, with particular interest in understanding frustrated spin systems in terms of emergent gauge/gravity/string theory. Implications of these highly entangled, topological many-body system may also shed light on high energy theories. Outside work I enjoy hitting the gym, swimming, and reading.

Research Unit Administrator

Megumi Ikeda

My duties are to assist unit members with any non-science problems so that they can excel with their academic work. My favorite part of my job is interacting with people and peeking at unit members while they struggle with overwhelming science!!
Outside of work, I enjoy traveling, reading and sleeping on the beach.
