Minkowski metric signature as a statistical prediction of piecewise-flat quantum gravity
Mihailo Djordjevic, Igor Prlina, Marko Vojinovic
We study an ab initio calculation of the signature of the spacetime metric, within the framework of piecewise-flat models of quantum gravity. Applying numerical techniques, we eval…
Detecting Hidden Nonlinear High Frequency Modes Beyond Fundamental Minimal Temporal Resolution Using Weak Measurements
Igor Prlina
In this work we study whether nonlinear models of quantum mechanics can avoid detection by strong measurements, if the nonlinear effects only exist as high frequency modes. A poten…
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…
Boundaries of Amplituhedra and NMHV Symbol Alphabets at Two Loops
Igor Prlina, Marcus Spradlin, James Stankowicz +1
In this sequel to arXiv:1711.11507 we classify the boundaries of amplituhedra relevant for determining the branch points of general two-loop amplitudes in planar su…
All-Helicity Symbol Alphabets from Unwound Amplituhedra
Igor Prlina, Marcus Spradlin, James Stankowicz +2
We review an algorithm for determining the branch points of general amplitudes in planar super-Yang-Mills theory from amplituhedra. We demonstrate how to use the re…
Landau Singularities from the Amplituhedron
Tristan Dennen, Igor Prlina, Marcus Spradlin +2
We propose a simple geometric algorithm for determining the complete set of branch points of amplitudes in planar N=4 super-Yang-Mills theory directly from the amplituhedron, witho…
