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. …”

Entropic Entanglement: Information Prison Break by Alexander Y. Yosifov, Lachezar G. Filipov

“…We argue that certain nonviolent local quantum field theory (LQFT) modification considered at the global horizon (r=2M) of a static spherically symmetric black hole can lead to adiabatic leakage of quantum information in the form of Hawking particles. …”

Symmetries, variational principles, and quantum dynamics by J. Manjavidze, A. Sissakian

“…The analysis shows that choosing the action-angle variables, one may get to the free-from-divergences quantum field theory. Moreover, one can try to get an independence from necessity to extract the degrees of freedom constrained by the symmetry. …”

A Generalization of Electromagnetic Fluctuation-Induced Casimir Energy by Yi Zheng

“…Though it is confirmation of the famous work of Dzyaloshinskii, Lifshitz, and Pitaevskii (DLP), we have solved the problem without having to use methods from quantum field theory that DLP resorted to. Because of this new approach, we have been able to clarify the contributions of propagating and evanescent waves to Casimir energy/pressure in dissipative media.…”
