Dynamical quantum phase transitions emerge from two distinct mechanisms: return singularities are separate from quantum interference effects that determine branch selection in phase space.

Researchers discover continuous temporal entanglement transitions in periodically driven quantum systems, where entanglement spectrum levels meet tangentially—extending phase transition theory beyond first-order transitions.

We derive closed-form expressions for quantum 'magic' in spin systems using real-space renormalization, revealing how this resource peaks at quantum phase transitions and enables accurate critical exponent extraction.
