Boundary Conditions that Remove Certain Ultraviolet Divergences by Roderich Tumulka

“…In quantum field theory, Hamiltonians contain particle creation and annihilation terms that are usually ultraviolet (UV) divergent. …”

The Search for the Universality Class of Metric Quantum Gravity by Riccardo Martini, Alessandro Ugolotti, Omar Zanusso

“…We use the language of the renormalization group and adopt several ideas which originate in the context of statistical mechanics and quantum field theory. Our discussion leads to several ideas that could affect the status of the asymptotic safety conjecture of quantum gravity and give universal arguments towards its proof.…”

Continuous entanglement renormalization on the circle by Ling-Yan Hung, Guifré Vidal

“…In addition, in the case of a Gaussian cMERA for noninteracting quantum fields, the method of images allows us to prove the following result: If on the line a cMERA state is a good approximation to a ground state of a local quantum field theory (QFT) Hamiltonian, then (under mild assumptions on their correlation functions) the resulting cMERA on a circle is also a good approximation to the ground state of the same local QFT Hamiltonian on the circle.…”

Why Cerenkov Radiation May Not Occur, Even When It Is Allowed by Lorentz-Violating Kinematics by Brett Altschul

“…In a Lorentz-violating quantum field theory, the energy-momentum relations for the field quanta are typically modified. …”

$W^{\pm }$ and $Z^0$ boson physics by Teubert, Frederic, Wells, Pippa

“…Precision measurements of the weak bosons ($Z^0$ and $W^{\pm }$) at $e^+ e^-$ and hadron colliders have allowed the Standard Model to be tested as a quantum field theory, requiring the inclusion of higher order quantum loop corrections. …”

Equal-time approach to real-time dynamics of quantum fields by Robert Ott, Torsten V. Zache, Jürgen Berges

“…We employ the equal-time formulation of quantum field theory to derive effective kinetic theories, first for a weakly coupled non-relativistic Bose gas, and then for a strongly correlated system of self-interacting $N$-component fields. …”

Hot Big Bang from inflation without the inflaton reheating by Alex Buchel

“…According to the standard lore, a prolonged inflation leaves a quantum field theory in a cold, low entropy state. Thus, some mechanism is needed to reheat this post-inflationary state, leaving a hot, thermal, radiation-dominated Universe. …”

Bounds on transport from hydrodynamic stability by L. Gavassino

“…Hence, the same bounds on transport that follow from causality in quantum field theory also emerge as stability conditions within relativistic hydrodynamics. …”

Optical Solitons for the Fokas-Lenells Equation with Beta and M-Truncated Derivatives by Farah M. Al-Askar

“…Since the FLE has various applications in telecommunication modes, quantum field theory, quantum mechanics, and complex system theory, the solutions produced may be used to interpret a broad variety of important physical process. …”

The Dirac Sea, <em>T</em> and <em>C</em> Symmetry Breaking, and the Spinor Vacuum of the Universe by Vadim Monakhov

Bethe–Salpeter Bound-State Solutions: Examining Semirelativistic Approaches by Lucha Wolfgang

“…Within the formalism of relativistic quantum field theory an adequate framework for the description of two-particle bound states, such as, for instance, all conventional (i.e., non-exotic) mesons, is provided by the Poincaré-covariant homogeneous Bethe–Salpeter equation. …”

Anomaly constraint on chiral central charge of (2+1)d topological order by Ryohei Kobayashi

“…For example, if a (2+1)d fermionic topological quantum field theory (TQFT) has a time-reversal anomaly with T^{2}=(−1)^{F} labeled as ν∈Z_{16}, the TQFT must have c_{−}=1/4 mod 1/2 for odd ν, while c_{−}=0 mod 1/2 for even ν. …”

Solutions of Yang–Baxter Equation of Mock-Lie Algebras and Related Rota Baxter Algebras by Amir Baklouti

“…It highlights the importance of the Yang–Baxter equation and symplectic forms in the study of integrable systems, quantum groups, and topological quantum field theory. The paper also proposes studying the admissible associative Yang–Baxter equation in algebras and characterizing Q-Admissible Solutions of the Associative Yang–Baxter Equation in Rota–Baxter Algebras. …”

When can gravity path-entangle two spatially superposed masses? by Marletto, C, Vedral, V

“…Collapse-type models, and also quantum field theory in curved spacetime, as well as various induced gravities, do not predict entanglement generation; they would, therefore, be ruled out as fundamental descriptions of gravity if entanglement were observed. …”

Space in monoidal categories by Tull, S, Heunen, C, Enrique Moliner, P

“…The category of Hilbert modules may be interpreted as a naive quantum field theory over a base space. Open subsets of the base space are recovered as idempotent subunits, which form a meet-semilattice in any firm braided monoidal category. …”

Duality and ontology by Le Bihan, B, Read, J

“…In recent times, dualities have been found to be pervasive in string theory and quantum field theory. Naïvely interpreted, duality‐related theories appear to make very different ontological claims about the world—differing in, for example, spacetime structure, fundamental ontology, and mereological structure. …”

Entanglement and correlation functions following a local quench: A conformal field theory approach by Calabrese, P, Cardy, J

“…We show that the dynamics resulting from preparing a one-dimensional quantum system in the ground state of two decoupled parts, then joined together and left to evolve unitarily with a translational invariant Hamiltonian (a local quench), can be described by means of quantum field theory. In the case when the corresponding theory is conformal, we study the evolution of the entanglement entropy for different bipartitions of the line. …”
