Passcode: Y8Rgv7

Unusual time: 3pm!

Solvable models are invaluable to understand the complex dynamics of many-body quantum systems. I will present two exact results on free fermions driven out of equilibrium. I will first show how to compute the time-dependent magnetization in the infinite-size Ising model when an arbitrary magnetic field is monitored, which was unknown before. In a second part I will show how to build solvable models for measurement-induced phase transitions between volume-law and area-law entangled states, and compute the associated critical exponents.
