Examples of slides I used in the past, summarizing some of my work:

From quantum chaos to entropy inflow
Non-linear gravity from entanglement in CFTs
A topological gauge theory for entropy and the emergence of hydrodynamics
Adiabatic hydrodynamics and the Eightfold Way to Dissipation
Permutation orbifolds and holography

Lecture Notes

As a student, I took notes for a few MSc level lecture courses at ETH Zurich and University of Zurich. May they be useful for someone:

Quantum Field Theory I
Quantum Field Theory II
General Relativity
Astrophysical and Cosmological Applications of General Relativity
