lemeshko_pic-216x300Prof. Dr. Mikhail Lemeshko


I grew up in South-West Russia and obtained an M.Sc. degree in experimental Condensed Matter Physics from the Southern Federal University in Rostov-on-Don.

In 2007 I moved to Berlin, Germany, in order to pursue a PhD in theoretical Molecular Physics with Prof. Bretislav Friedrich at the Fritz Haber Institute of the Max Planck Society. Our work was mainly concerned with a theoretical treatment of molecules in electric, magnetic and radiative fields, including field-dressed molecular collisions.

In 2011 I was awarded an ITAMP postdoctoral fellowship at Harvard University and moved to Cambridge MA in the United States. My research at ITAMP mostly focused on many-body physics of ultracold molecules, and dissipative state preparation in ultracold gases.

Since September 2014 I am an Assistant Professor at the recently established Institute of Science and Technology Austria (IST Austria). The main direction of my current research is understanding the physics of quantum impurities possessing orbital angular momentum. In addition, I’m interested in out-of-equilibrium behavior of cold atoms and molecules and using engineered dissipation as a tool to create novel few- and many-body states of matter.

Curriculum Vitae in pdf

I was born in Kunming, China — a small town however known as a tourist attraction. In 2007, I moved out hometown to Xi’an in the northwestern part of China, where I received higher education and M.Sc. degree. During those years, my major academic interest was in nonlinear optics theory, and one of my hobbies was to translate interesting scientific news and short stories to Chinese and publish them online.
Afterwards, I decided to keep heading towards northwest and moved to Austria to pursue a PhD in theoretical Quantum Physics with Prof. Dr. Mikhail Lemeshko. The main focus of my current research is on the strong-coupling limit of the angulon theory and self-localization transition.

Curriculum Vitae in pdf

I was born in a small town Sokol, Vologda Region in North-West Russia. In 2010, I enrolled in the Physics Department of the Saint-Petersburg State University (SPbSU). Two years later, I joined the research group of Prof. Anatoly Pravilov. In 2014 and 2016, I obtained my B.Sc. and M.Sc. degrees in Molecular Physics, respectively. My work was mainly focused on experimental studies of electronically excited states of iodine molecule and revealing the coupling mechanisms between

them. Since July 2016, I am a Ph.D. Student at IST Austria in the group of Prof. Mikhail Lemeshko. We are developing a quasiparticle approach based on the angulon theory in order to describe the behavior of rotating molecules trapped inside in superfluid 4He nanodroplets. Apart from physics, I like to play chess and some other intellectual games. Therefore, don’t hesitate to challenge me.

Curriculum Vitae in pdf

I was born, raised, and educated in Warsaw, the capital of Poland. There, I completed my BSc (2015) and MSc (2017) degrees in physics with Prof. Rafał Demkowicz-Dobrzański at the University of Warsaw and a BSc Eng degree (2015) in electronic and computer engineering with Prof. Kajetana Snopek at the Warsaw University of Technology. After doing a summer internship at IST Austria in 2016, I was so positive about it that I decided to eventually leave Warsaw and started a PhD here in 2017, joining the group of Prof. Mikhail Lemeshko in 2018.

I currently focus on extending the angulon theory in order to provide more physical insight into the experimental data on molecules rotating in quantum solvents. When I’m not doing this, I travel avidly and enjoy learning foreign languages.

Curriculum Vitae in pdf

I was born and grew up in a small town near Venice, Italy. I went on to study Physics at the University of Padua, were I completed my Bachelor’s, Master’s and Ph.D. My Ph.D. thesis analyzed on the role of order parameter fluctuations in the BCS-BEC crossover and in high-Tc cuprate superconductors, under the supervision of Prof. L. Salasnich and Prof. P.A. Marchetti.

In September 2016 I moved to Vienna where I joined the group of Prof. Lemeshko at IST Austria. Here I plan on applying my experience in condensed matter and ultracold gases to the angulon theory.

Apart from physics, I like playing my guitars and skiing.

Curriculum Vitae in pdf

I grew up in Turkey and obtained my M.Sc. degree in Mathematical Physics from Middle East Technical University, Ankara, where I studied relativistic quantum information under the supervision of Prof. N.K. Pak.

At the end of 2010, I moved to Max Planck Institute for Nuclear Physics, Heidelberg, Germany for my doctoral study in the division of Theoretical Quantum Dynamics and Quantum Electrodynamics led by Prof. C. H. Keitel. The main subject of my Ph.D. research was the theoretical description of relativistic tunneling and tunneling time delay in a tunnel-ionization process. I completed my Ph.D. studies in early 2014 and stayed at the same place as a postdoc until April 2016.

Since May 2016, I’m an IST postdoctoral fellow at IST Austria in the Theoretical Atomic, Molecular, and Optical Physics group led by Prof. M. Lemeshko.
