    Scattering of spinning compact objects from a worldline EFT by Maor Ben-Shahar

    Published 2024-03-01
    “…Abstract We study the EFT of a spinning compact object and show that with appropriate gauge fixing, computations become amenable to worldline quantum field theory techniques. We use the resulting action to compute Compton and one-loop scattering amplitudes at fourth order in spin. …”

    All about the neutron from lattice QCD by Rajan Gupta

    Published 2024-04-01
    “…Both constructs are stochastic, so unfortunately one gets no intuitive picture or even qualitative understanding of what they look like, nevertheless they contain and display all the subtleties of the quantum field theory. Today, these simulations provide many quantities that are impacting phenomenology and experiments. …”

    Curvature-induced skyrmion mass by Alexander Pavlis, Christina Psaroudaki

    Published 2020-09-01
    “…We investigate the propagation of magnetic skyrmions on elastically deformable geometries by employing imaginary time quantum field theory methods. We demonstrate that the Euclidean action of the problem carries information of the elements of the surface space metric, and develop a description of the skyrmion dynamics in terms of a set of collective coordinates. …”

    Is the horizon of an eternal black hole really smooth? by Nissan Itzhaki

    Published 2023-05-01
    “…In particular, we argue that the bulk modes responsible for Poincare recurrence, when it occurs in the dual quantum field theory, are either instant folded strings or instant folded D-branes.…”

    Dynamics and classification of RNA strands by Heng, Wang Cong

    Published 2017
    “…When N is large, the relationship between the genus and RNA with pseudoknots is found to be closely related to the Feynman diagrams of Quantum Field theory. This allows the classification of RNA according to this topological genus. …”

    Revisiting the Okubo–Marshak Argument by Christian Gaß, José M. Gracia-Bondía, Jens Mund

    Published 2021-09-01
    “…Modular localization and the theory of string-localized fields have revolutionized several key aspects of quantum field theory. They reinforce the contention that <i>local</i> symmetry emerges directly from quantum theory, but global gauge invariance remains in general an unwarranted assumption to be examined case by case. …”

    Mohand homotopy transform scheme for the numerical solution of fractional Kundu–Eckhaus and coupled fractional Massive Thirring equations by Xiankang Luo, Muhammad Nadeem

    Published 2023-03-01
    “…The massive Thirring model consists of a system of two nonlinear complex differential equations, and it plays a dynamic role in quantum field theory. We combine Mohand transform with homotopy perturbation scheme and show the results in the form of easy convergence. …”

    Multiplicative Renormalization of Stochastic Differential Equations for the Abelian Sandpile Model by Dimitri Volchenkov

    Published 2024-01-01
    “…The long-term, large-scale behavior in a problem of stochastic nonlinear dynamics corresponding to the Abelian sandpile model is studied with the use of the quantum-field theory renormalization group approach. We prove the multiplicative renormalization of the model including an infinite number of coupling parameters, calculate an infinite number of renormalization constants, identify a plane of fixed points in the infinite dimensional space of coupling parameters, discuss their stability and critical scaling in the model, and formulate a simple law relating the asymptotic size of an avalanche to a model exponent quantifying the time-scale separation between the slow energy injection and fast avalanche relaxation processes.…”

    AdS2 holography and effective QFT by Sangmin Choi, Finn Larsen

    Published 2023-11-01
    “…However, it may be advantageous that our derivation just relies on conventional AdS/CFT correspondence and effective quantum field theory. For example, it clarifies the symmetry breaking pattern. …”

    Spectrum of the hypereclectic spin chain and Pólya counting by Changrim Ahn, Matthias Staudacher

    Published 2022-12-01
    “…In earlier work we proposed a generating function that encodes the Jordan block spectrum of the integrable Hypereclectic spin chain, related to the one-loop dilatation operator of the dynamical fishnet quantum field theory. We significantly improve the expressions for these generating functions, rendering them much more explicit and elegant. …”

    Scaling solutions for asymptotically free quantum gravity by Saswato Sen, Christof Wetterich, Masatoshi Yamada

    Published 2023-02-01
    “…The existence of such scaling solutions is necessary for a renormalizable quantum field theory of gravity. If the proposed scaling solution is con- firmed beyond our approximations asymptotic freedom is a viable alternative to asymptotic safety for quantum gravity.…”

    CPT Symmetry and Its Violation by Ralf Lehnert

    Published 2016-10-01
    “…This article reviews the conditions under which CPT symmetry holds by recalling two proofs of the CPT theorem: The original Lagrangian-based analysis and the more rigorous one in the context of axiomatic quantum field theory. The presentation of the proofs is followed by a discussion of the major physical implications that arise from CPT symmetry. …”
