Prethermal cooling with many-body quantum quenches
Jacob F. Steiner, Mohammad Hafezi, Stefan Kehrein +1
Many-body quantum quenches are typically associated with heating. In this work, we show that quantum quenches that perform positive work on the system can still lead to effective c…

Measurement-induced Clock in a Lattice Ring of Non-interacting Electrons
David S. Schlegel, Stefan Kehrein
We examine the emergence of periodicity in a non-interacting steady-state quantum system without external drive inspired by quantum time crystals' spontaneous time-translation symm…

Page curve entanglement dynamics in an analytically solvable model
Stefan Kehrein
The entanglement entropy of black holes is expected to follow the Page curve. After an initial linear increase with time the entanglement entropy should reach a maximum at the Page…
