Quantum Information
Information theory has enlightened our understanding of quantum phenomena. Given the high computational complexity of quantum entropies, I'm interested in finding more universal and accessible descriptions, for instance using classical entropies to probe quantum features. Further, I investigate information in phase space for continuous variables, fermions and spins.
Quantum Fields
Not only three out of four forces and Bose-Einstein condensation can be described within field theories, but also entanglement, uncertainty, thermalization and quanta in curved space. I'm curious about understanding entanglement, information spreading, phase transitions, thermalization, quantum field simulators and entropic uncertainty for quantum fields.
Gravity
Spacetime is geometry. I'm especially fascinated by quantum gravity and analog gravity, that is, the simulation of gravitational phenomena and their interplay with quantum phenomena using table-top experiments. Here, I'm working on the black hole information paradox and analog models realizable via cold atom platforms to test entanglement in cosmology and Hawking radiation.
Cold atoms
Over the last two decades, cold atom experiments have proven to serve as ideals testbeds for investigating all the phenomena I'm interested in. I regularly explore the possibilities of Bose-Einstein condensates and their theoretical models and enjoy the insightful collaborations with various experimentalists.
Phenomena
Entanglement
How can entanglement be characterized and certified efficiently, also for continuous-variable and quantum many-body systems? Which role does entanglement play in field theories, thermalization and quantum phase transitions? How does entanglement spread in and connect spacetime? How is entanglement related with gravity?
Uncertainty
What is the strongest and most general formulation of the uncertainty principle? How are uncertainty relations for different types of variables related? How can uncertainty relations be devised for field theories? How can uncertainty relations help to formulate entanglement witnesses and constrain quantum entropies?
Thermalization
How can equilibrium and non-equilibrium situations be described in field theories? How does the mesoscopic local equilibrium arise from microscopic degrees of freedom and entanglement? When and how do isolated quantum systems thermalize locally? How can local thermalization be certified efficiently? How can local temperatures be measured?
Quanta in curved space
Which entropic descriptions capture the observer-dependence of particles and entanglement accurately? How can quantum phenomena in curved spacetime such as Hawking radiation and cosmological particle production be accessed by quantum field simulators? How does information escape from black holes?
