Meet Our Team

Meet our team of international researchers with various scientific backgrounds. Our interests span from quantum information in quantum field theories, computational complexity and AdS/CFT correspondence to running, playing piano, high jumping and break dance.

Paweł Caputa, Ph.D.

Group Leader

Paweł Caputa is a faculty member at the University of Warsaw and the leader of our group founded by the „Polish Returns 2019” program of NAWA. Before coming back to Poland, he was the It from Qubit  fellow and research assistant professor at the Yukawa Institute for Theoretical Physics in Kyoto, Japan. He received his Ph.D. from the Niels Bohr Institute in Copenhagen in 2011 and was a postdoctoral researcher at the University of the Witwatersrand in Johannesburg, South Africa, and the Nordic Institute for Theoretical Physics in Stockholm, Sweden, bridged by the short-term Japan Society for the Promotion of Science fellowship in Kyoto. He has worked on integrability, 1/N corrections and tests of the AdS/CFT correspondence. His recent work focuses on entanglement dynamics and complexity in quantum field theories, emergent geometry from entanglement, quantum gravity and AdS/CFT.

Dongsheng Ge, Ph.D.

Post-Doc

Hey, I am Dongsheng, a postdoc at QIQG group at the University of Warsaw. Originally I am from Huanggang, a small city near Wuhan. After I graduated from Wuhan University, I started my academic and cultural journey in Europe. I have been enrolled in the Joint Master Program of High Energy Physics between ETH Zurich and Ecole Polytechnique of Paris, where I spent one year at each institute. Paris has been attractive to me, thus I stayed at Ecole Normale Superieure de Paris for the last four years, where I obtained my PhD under the supervision of Dr. Giuseppe Policastro. In terms of research, I have been fascinated by the holographic way of understanding the nature of physics. It offers a rather special perspective to anatomise the geometry of the spacetime, so as  to uncover certain information hidden behind. More specifically, I have been exploring the gravitational aspects of some quantum information objects such as the entanglement entropy and quantum complexity, as well as understanding them from a QFT perspective. Another facet of my current research interests is to understand the gluing of both gravitational theories and quantum field theories, nouveau features usually arise in this setup…

Sinong Liu, Ph.D.

Post-Doc

This is Sinong, a postdoc in QIQG group at the University of Warsaw. During the past ten years I was all the way north. Leaving from my hometown Fuzhou I went to Fudan University in Shanghai for my undergraduate education, then I became the student of Professor Sumit R. Das and was conferred a Ph.D degree at University of Kentucky in USA, and finally I am in Warsaw. Looking back at the past years, my researches consist of a bit of non-equilibrium physics associated with quantum quench, a bit of tensor network as a means of understanding AdS/CFT correspondence, and a bit of applications of quantum entanglement and complexity. I am still interested with all those topics, and I am still curious about more.

Dimitrios Patramanis, M.Sc.

Graduate Student

Dimitrios started his academic career in the field of chemistry where he received Bachelor’s degree. However, it was not long before he realized that his true interests lied in theoretical physics which was broadly the topic
of his Master’s level studies. More specifically, Dimitrios is fascinated by  inquiries about the microscopic constituents of our universe and how those can give birth to the large scale structures that we observe. Currently, Dimitrios  research focuses on aspects of holography and in particular the AdS/CFT correspondence. These serve as tools for the construction of toy models that can help us reconcile Einstein’s general relativity and quantum field theory in a controlled setting while also opening a path leading to a full-fledged theory of quantum gravity suitable for describing our universe.  Moreover, Dimitrios is also very interested in science communication and popularization.

Jan Boruch, M.Sc.

Graduate Student

My main area of research is the AdS/CFT correspondence. In particular, I am interested in questions which might lead us to better understanding of quantum aspects of gravity. One of the prominent approaches heavily developed in recent years goes under the title “spacetime emergence from entanglement”. In this approach we try to investigate whether one can think of spacetime as an effective description of the complicated entanglement patterns of the strongly coupled dual field theory. Part of my research focuses on studying path integral optimization approach to holography, as well as investigating various field theory entanglement measures from the perspective of AdS/CFT. Another, much older, approach to studying quantum gravity investigates thermodynamics of black holes by studying Euclidean gravitational path integral. This approach was developed before the discovery of AdS/CFT, but gained many important physical insights from holography. My research also focuses on trying to understand the leading quantum effects on the thermodynamics of near-extremal black holes.

Michał Bączyk, M.Sc.

Graduate Student
I am a team player and in my opinion it is best to set out on a journey towards the unknown together, helping each other along the way and sharing the joy of discovering the world.
I started my Physics journey in high school when I conducted my first independent research. For that work I was awarded 1st prize in the 27th European Union Contest for Young Scientists (EUCYS) becoming the best young scientist in Europe. Afterwards, I graduated with a BA degree in Physics from St Catharine’s College at the University of Cambridge. Eventually, I completed my Master’s studies at ETH Zurich where I specialized in quantum information.
I am fascinated with the research in quantum gravity because, for me, it is remarkable how this field merges ideas from various disciplines. The knowledge of quantum information, field theory, string theory, statistical thermodynamics, condensed matter, many-body physics and general relativity is indispensable when it comes to investigating the quantum structure of spacetime, black hole physics or the information loss paradox.
My first work in the area was my Master’s thesis completed in the Quantum Information Theory group at ETH within the collaboration with Paweł Caputa. Right now, continuing the studies we already completed we would like, as a novel idea in holography and CFT in general, to introduce the operational notions of channels into the language of field theories which would allow us to quantify with quantum information tools the quantum evolution of holographic states. Our further research directions would involve geometric descriptions of dynamical states in CFT and Holographic Tensor Networks for time-dependent states.
