The other QFT

Nature Physics, 2015
Fluctuation theorems go beyond the linear response regime to describe systems far from equilibrium. But what happens to these theorems when we enter the quantum realm? The answers, it seems, are now coming thick and fast.

Emergent gravity as the eraser of anomalous gauge boson masses, and QFT-GR concord

General Relativity and Gravitation, 2021
In the same base setup as Sakharov’s induced gravity, we investigate emergence of gravity in effective quantum field theories (QFT), with particular emphasis on the gauge sector in which gauge bosons acquire anomalous masses in proportion to the ...

Interval QFT: a mathematical and computational enhancement of QFT

International Journal of Robust and Nonlinear Control, 2002
AbstractThe paper presents an overview of a mathematical and computational enhancement of Horowitz's QFT design procedure. The enhancement uses methods of interval analysis and is called as interval QFT, or IQFT. IQFT addresses and solves some of the fundamental issues in QFT, concerning selection of design frequencies, selection of controller phases ...
