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…
