What's the Matter with 3D Gravity?
Robert Bourne, Jackson R. Fliss, Bob Knighton
We revisit the problem of minimally coupling matter to Einstein gravity in three dimensions with negative cosmological constant. By working in the worldline formalism, we construct…
Fortuity and Complexity in a Simple Quark Model
Jackson R. Fliss, Vishnu Jejjala, Onkar Parrikar
We observe and elaborate on a structural similarity between the categorization of monotone and fortuitous BPS operators in supersymmetric theories and gauge invariant quark operato…
Modave lectures on energy conditions in quantum field theory and semi-classical gravity
Jackson R. Fliss
We review well known classical energy conditions and their implications for gravitational solutions, including the celebrated Hawking and Penrose singularity theorems. We then cons…
Medicine show: A Calogero model with principal series states
Tarek Anous, Jackson R. Fliss, Jeremy van der Heijden
The Calogero model is an interacting, -particle, -invariant quantum mechanics, whose Hilbert space is furnished by a tower of discrete series modules…
Curious QNEIs from QNEC: New Bounds on Null Energy in Quantum Field Theory
Jackson R. Fliss, Andrew Rolph
We derive new families of quantum null energy inequalities (QNEIs), i.e. bounds on integrated null energy, in quantum field theories in two and higher dimensions. These are univers…
Matrix Quantum Mechanics and Entanglement Entropy: A Review
Jackson R. Fliss, Alexander Frenkel
We review aspects of entanglement entropy in the quantum mechanics of matrices, i.e. matrix quantum mechanics (MQM), at large . In doing so we review standard models…
