Metric field as emergence of Hilbert space by Maysam Yousefian, Mehrdad Farhoudi

“…Accordingly, such an augmented Hilbert space includes quantum field theory in a general frame and can be considered as a fundamental concept instead of the classical metric field and the standard Hilbert space.…”

Excitations in strict 2-group higher gauge models of topological phases by Alex Bullivant, Clement Delcamp

“…This model, which has a higher gauge theory interpretation, provides a lattice Hamiltonian realisation of the Yetter homotopy 2-type topological quantum field theory. The Hamiltonian yields bulk flux and charge composite excitations that are either point-like or loop-like. …”

Peculiar index relations, 2D TQFT, and universality of SUSY enhancement by Matthew Buican, Linfeng Li, Takahiro Nishinaka

“…By writing these quantities in the language of 2D topological quantum field theory (TQFT), we easily read off the S-duality action on the flavor symmetries of the AD quivers and also find expressions for the Schur indices of various classes of exotic AD theories appearing in different decoupling limits. …”

Anomalies of QFTs from M-theory and holography by Ibrahima Bah, Federico Bonetti, Ruben Minasian, Emily Nardoni

Operator dimension parity fractionalization by Christopher W. Murphy

“…Abstract Lorentz invariant quantum field theories (QFTs) with fermions in four spacetime dimensions (4D) have a ℤ 4 symmetry provided there exists a basis of operators in the QFT where all operators have even operator dimension, d, including those with d > 4. …”
