The Autodidactic Universe
Stephon Alexander, William J. Cunningham, Jaron Lanier +4
We present an approach to cosmology in which the Universe learns its own physical laws. It does so by exploring a landscape of possible laws, which we express as a certain class of…
Soft modes in SYK model
Cheng Peng, Stefan Stanojevic
We study various properties of the soft modes in the supersymmetric SYK model.
Scattering Amplitudes and Simple Canonical Forms for Simple Polytopes
Giulio Salvatori, Stefan Stanojevic
We provide an efficient recursive formula to compute the canonical forms of arbitrary -dimensional simple polytopes, which are convex polytopes such that every vertex lies preci…
On phase transitions in the Rényi entropies of 2+1-d large-N interacting vector models
Harsha R. Hampapura, Albion Lawrence, Stefan Stanojevic
We consider the reduced density matrix for a disc in the ground state of the interacting fixed points of the large-N O(N) vector model in 2+1 dimensions. Using the map to the free…
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…
