## Scope

Positive energy conditions fulfilled by many matter fields in classical field theory are violated in quantum field theory (QFT), so the quantum energy density can have negative expectation values. This raises fundamental questions.

For example, are the energy conditions that enter as an assumption of singularity theorems in general relativity (GR) compatible with quantum matter or do quantum fields allow the existence of “exotic” spacetimes?

If such scenarios are to be excluded, there must be constraints to the extent in which quantum fields can cause negative energy densities. Those constraints are known as quantum energy inequalities (QEI) or quantum energy conditions (QEC). These inequalities appear to be related to other interesting physical aspects of QFT, such as the notion of thermal equilibrium, as well as aspects of information theory, for example the relative entropy.

The aim of this conference is to bring together experts working on different aspects of energy conditions in QFT to present recent results and discuss perspectives for future directions. The main topics will be:
