Quantum field theory for spin operator of the photon by Li-Ping Yang, Farhad Khosravi, Zubin Jacob

“…Within quantum electrodynamics (QED), even though the spin of the Dirac particle is well defined, there exist open questions on the quantized description of spin of the gauge field particle—the photon. Using quantum field theory, we discover the quantum operators for the spin angular momentum (SAM) S_{M}=(1/c)∫d^{3}xπ×A and orbital angular momentum (OAM) L_{M}=−(1/c)∫d^{3}xπ^{μ}x×∇A_{μ} of the photon, where π^{μ} is the conjugate canonical momentum of the gauge field A^{μ}. …”

Unfolded dynamics approach and quantum field theory by Nikita Misuna

“…Then we systematically construct three different but related unfolded formulations of the corresponding quantum field theory, supporting them with illustrative calculations: an unfolded functional Schwinger-Dyson system, an unfolded system for correlation functions and an unfolded effective system for vertex functions. …”

Symmetries in Quantum Field Theory and Quantum Gravity by Harlow, Daniel, Ooguri, Hirosi

“…An essential point, which we dwell on at length, is precisely defining what we mean by gauge and global symmetries in the bulk and boundary. Quantum field theory results we meet while assembling the necessary tools include continuous global symmetries without Noether currents, new perspectives on spontaneous symmetry-breaking and ’t Hooft anomalies, a new order parameter for confinement which works in the presence of fundamental quarks, a Hamiltonian lattice formulation of gauge theories with arbitrary discrete gauge groups, an extension of the Coleman–Mandula theorem to discrete symmetries, and an improved explanation of the decay $$\pi ^0\rightarrow \gamma \gamma $$ π 0 → γ γ in the standard model of particle physics. …”

Entanglement and Chaos in Quantum Field Theory and Gravity by Wei, Annie Y.

“…First we study quantum scars, a phenomenon previously studied in chaotic, few-body quantum systems, and we extend the analysis from the case of few-body quantum mechanics to the case of quantum field theory. Next we turn to the study of multipartite entanglement. …”
