Quantum-induced trans-Planckian energy near horizon

Journal of High Energy Physics, 2018
We study the loop effects on the geometry and boundary conditions of several black hole spacetimes one of which is time-dependent and analyze the energy measured by an infalling observer near their horizons.

States of low energy in the Schwinger effect

Journal of High Energy Physics, 2023
States of low energy in cosmology minimise the energy density when smeared in a chosen time interval. We extend such construction to generic homogeneous (possibly anisotropic) particle creation settings.

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

Advanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Multimodal Fragmentation of Hidden‐Heavy Scalar Tetraquarks With HF‐NRevo

Annalen der Physik, Volume 538, Issue 10, October 2026.
A state‐driven multimodal framework is introduced for hidden‐heavy scalar tetraquark fragmentation. Distinct microscopic production mechanisms are consistently related to different internal hadronic configurations while theoretical uncertainties are systematically quantified.

Foundations of Wilson Lines and Loops From Basic Concepts to Gauge Field Reconstruction

Fortschritte der Physik, Volume 74, Issue 10, October 2026.
Wilson lines and Wilson loops are reviewed as parallel transport observables in continuum gauge theory. Full holonomy data recover the local connection and curvature through short segment and small loop limits. Traced Wilson loops are gauge invariant but lose matrix information, so reconstruction requires a compatible lift constrained by trace ...

Phase-locking in dynamical systems and quantum mechanics

Journal of High Energy Physics
In this study, we discuss the Prüfer transform that connects the dynamical system on the torus and the Hill equation, which is interpreted as either the equation of motion for the parametric oscillator or the Schrödinger equation with periodic potential.

Topology in full QCD at high temperature: a multicanonical approach

Journal of High Energy Physics, 2018
We investigate the topological properties of N f = 2 + 1 QCD with physical quark masses, at temperatures around 500 MeV. With the aim of obtaining a reliable sampling of topological modes in a regime where the fluctuations of the topological charge Q are

Operating a Contextual Stern–Gerlach Apparatus

Annalen der Physik, Volume 538, Issue 9, September 2026.
We reappraise the Stern–Gerlach experiment in view of the contextual monitoring of a cavity QED system output. The dynamical collapse of a macroscopic coherent‐state superposition for the cavity field, allowing for a binary outcome in the “spin” degree of freedom, is complementary to the persistence of quantum interference, after passing through ...

Quantum Plasmonic Dynamics Modeled via a Modified Langevin Noise Formalism: Numerical Studies of Single‐Photon Emission and Two‐Photon Interference

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
Based on the modified Langevin noise formalism and BA‐MA theory, optimized computational formulations are demonstrated for quantum plasmonic simulations without explicit BA–MA mode construction. Plasmonic Hong‐Ou‐Mandel interference, g2, atomic population, and single‐photon probability amplitudes are efficiently analyzed, revealing directional single ...

Asymptotic charges, large gauge transformations and inequivalence of different gauges in external current QED

Journal of High Energy Physics, 2019
In this paper we consider external current QED in the Coulomb gauge and in axial gauges for various spatial directions of the axis. For a non-zero electric charge of the current, we demonstrate that any two different gauges from this class correspond to ...
