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.

David is interested in novel features in nonlinear light-matter interactions in Dirac materials, as well as methodologies to retrieve topological character from various condensed matter systems. Examples of such media include graphene, boron nitride, and transition metal dichalcogenides. On a computational side, he is involved in the Organic Material Data Base (OMDB) and Machine Learning methodologies in high throughput predictions.

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.

Sumanta Bandyopadhyay
Postdoctoral Researcher

Sumanta has received his Ph.D. from Washington University in St Louis. There he has developed mathematical techniques to extract topological information from strongly interacting 2D materials under high magnetic field.

Currently, he is working on realizing the odd frequency superconducting states in the gain-loss system. Sumanta is mainly interested in multicritical quantum phase transitions, axion detection and prediction of topological properties in materials.

Vladimir Zyuzin
Postdoctoral Researcher

Vladimir is currently working on Bose-Einstein condensation of Dirac magnons.  Previously he has worked on disordered two-dimensional interacting fermion systems. There, in particular, a possibility of odd-frequency pairing was studied.
He has also worked on Tomonaga-Luttinger liquids, Fermi liquids, Berry curvature driven transport of magnons, spin-orbit coupling, and on some properties of Weyl semimetals.

Long Liang
Postdoctoral Researcher

Long Liang received his PhD from the Institute of Theoretical Physics, Chinese Academy of Science in 2016. Then he was a postdoctoral researcher at the Department of Applied Physics, Aalto University, where he mainly worked on flat band superconductivity and Weyl semimetals.  Now Long is a joint Postdoctoral fellow at Nordita and Tsung-Dao Lee Institute. His research interests lie in topological and geometric (e.g., quantum metric) effects of quantum matter. Currently, he is working on Weyl semimetals in emergent torsional spacetime.
