Alexander V. Balatsky
Professor & Group Leader

Alexander V. Balatsky completed his Masters at Moscow Physical Technical Institute in 1984 and his PhD at the Landau Institute in Moscow in 1987, where he presented his thesis On Anomalous Angular Momentum of Superfluid He3-A under the supervision of V. Mineev and G. Volovik. He later carried out postdoctoral research at the University of Illinois Urbana-Champaign with Prof D. Pines and C. Pethick.


Prof. Balatsky's focus lies on Dirac materials and their dynamics, as well as on materials informatics in quantum materials.  In this class of materials strong quantum correlations lead to entangled and resonating orders that often are hidden from conventional observations. Examples include topological and nodal orders of fermions and bosons and dynamic orders.  In his group, he develops the framework to understand, predict and ultimately control emergence of these orders in quantum materials. Additionally, he is also interested in the prediction and analytics of quantum materials properties through a variety of tools including data mining and machine learning to characterize and predict electronic structure, magnetism and superconductivity of organic materials.

Ivan Khaymovich
Assistant Professor
Ivan received his PhD from the Institute for Physics of Microstructures (Russia) in 2013. His research includes 
- induced superconductivity, 
- non-equilibrium overheating of superconducting devices and methods to diminish it,
- Coulomb-blockaded devices, quantum heat transport
- stochastics thermodynamics, Maxwell's demon paradox, and fluctuation relations,
- quantum thermalization breakdown in random-matrix models, disordered many-body quantum systems, and on the random networks and graphs,
- non-Hermitian effects in disordered and interacting quantum systems.

His main interest is the realization and stabilization of the ergodicity breaking phases of matter, relevant to machine learning/quantum search algorithm speed-ups and superconductivity enhancement.

Tien Tien Yeh
Postdoctoral Researcher

Tien-Tien received her Ph.D. in Electrophysics from the National Chiao Tung University, Taiwan (R.O.C) in January 2020. Then Tien-Tien was a postdoctoral fellow at the National Synchrotron Radiation Research Center, Taiwan, where she focused on developing fs-time-resolved spectroscopies, including microscopy and ARPES. Following this, she became a postdoctoral researcher at Stockholm University, Sweden. She developed a new phase retrieval method for THz reflection spectroscopy. Currently, she is working on theoretical simulations of light-matter interactions in superconducting materials and devices. Her research interests lie in the dynamics of light-matter interaction in quantum matter.

Dushko Kuzmanovski
Postdoctoral Researcher

Dushko received his PhD in the Department of Physics at the University of Wisconsin-Madison in 2014, United States, defending a thesis titled “Transport and thermodynamic properties of iron-based superconductors” under the supervision of Prof. Maxim G Vavilov. After, he was a postdoctoral researcher in the Materials Theory Division at Uppsala University, Sweden. Working in the group of Prof. Annica Black-Schaffer until 2017, his work was centered around silicene heterostuctures with proximity induced superconductivity as viable platforms that can host Majorana fermions as well as odd-frequency superconductivity. Working with Prof. Johan Nilsson until 2019, he worked on novel and alternative approaches to strongly interacting electrons, focusing on the Hubbard model as a prototypical test-bed.


Currently, he is working on Dynamic Quantum Matter, with main focus on superconducting systems. His broad interests continue to be aspects of the role of various kinds disorder and coexistence of phases in novel unconventional superconducting materials, strongly-correlated electron systems, especially in their relation to signatures in quantum transport and response.
