Postdoctoral Fellow in Theoretical Physics
The goal of the project is to develop universal measures of quantum complexity for many-body systems, quantum field theories and quantum gravity. Ref. No. SU FV-3826-25, closing date: 17 December 2025.
Project description
Complexity is a fundamental concept that quantifies the difficulty of accomplishing a particular task, given a specific set of allowed, simple operations and a procedure to achieve it. As such, it is an important part of many fields from mathematics to computer science. Surprisingly, physics still lacks a precise definition of quantum complexity and providing it is one of the most urgent problems at the cutting-edge of quantum theory and quantum gravity.
The position within the ERC Consolidator project “Quantum Complexity from Quantum Field Theories to Quantum Gravity” (PI: Pawel Caputa) will aim to fill this gap.
The goal of the project is to develop universal measures of quantum complexity for many-body systems, quantum field theories and quantum gravity. The milestones of the project include: synthesizing and developing physical measures of complexity, formulating them in exact holographic models, and applying them to shed new light on the physics behind black hole horizons and spacetime singularities.
Main responsibilities
The position involves mostly research conducted in a close collaboration with the PI, one PhD student, as well as other members of the group. The responsibilities will also include help in organizing standard group activities.
