If Quantum Measurements Are Secretly Continuous Nonunitary Processes, Weak Measurements Can Detect It
Igor Prlina, Milutin Živković
The standard approach to quantum measurements is to assume that they lead to effectively instantaneous collapse of the quantum state. However, if we assume that we are unable to en…

If Mixed States Are Secretly Quickly Oscillating Pure States, Weak Measurements Can Detect It
Igor Prlina
The apparent nonunitary evolution in the black hole information paradox and recent work on describing wavefunction collapse via nonunitary nonlinear stochastic operators has motiva…

All-loop singularities of scattering amplitudes in massless planar theories
Igor Prlina, Marcus Spradlin, Stefan Stanojevic
In massless quantum field theories the Landau equations are invariant under graph operations familiar from the theory of electrical circuits. Using a theorem on the - reducib…
