Proof of the quantum null energy condition for free fermionic field theories

The quantum null energy condition (QNEC) is a quantum generalization of the null energy condition which gives a lower bound on the null energy in terms of the second derivative of the von Neumann entropy or entanglement entropy of some region with respect to a null direction. Expand abstract.

A mathematical framework to compare classical field theories

To construct the mathematical framework, a mathematical category (in the sense of category theory) in which a versatile comparison becomes possible is sought and the geometric theory of partial differential equations is used to define what can be understood by a correspondence between theories and by an intersection...

Zero-point energies, dark matter, and dark energy

A quantum field theory has finite zero-point energy if the sum over all boson modes $b$ of the $n$th power of the boson mass $ m_b^n $ equals the sum over all fermion modes $f$ of the $n$th power of the fermion mass $ m_f^n $ for $n= 0$, 2, and 4. Expand abstract.

Towards a conformal field theory for Schramm-Loewner evolutions

We discuss the partition function point of view for chordal Schramm-Loewner evolutions and their relationship with correlation functions in conformal field theory. Expand abstract.

Genus theory and Euclidean ideals for real biquadratic fields

In this paper, we use the theory of genus fields to study the Euclidean ideals of certain real biquadratic fields $K.$ Comparing with the previous works, our methods yield a new larger family of real biquadratic fields $K$ having Euclidean ideals; and the conditions for our family seem to be more efficient for the computations.

Superconformal algebras and holomorphic field theories

We compute the holomorphic twists of four-dimensional superconformal algebras, and argue that the resulting algebras act naturally by holomorphic vector fields on holomorphically twisted superconformal theories. Expand abstract.

Anomalies of QFTs from M-theory and Holography

We describe a systematic way of computing the 't Hooft anomalies for continuous symmetries of Quantum Field Theories in even dimensions that can be geometrically engineered from M5-branes. Expand abstract.
