Self‐Creation of Accelerated Temporal Mirrors
Advanced Physics Research, EarlyView.The field of temporal analog effects is rapidly emerging and seen as a driver of a paradigm shift in photonics. It promises striking new phenomena but remains experimentally challenging. This work introduces a mechanism that automatically creates a temporal mirror with simple optical means, unlocking practical access to extreme nonlinear dynamics and ...

A Physically-Motivated Quantisation of the Electromagnetic Field on Curved Spacetimes
Entropy, 2019 Recently, Bennett et al. (Eur. J. Phys. 37:014001, 2016) presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space.

The Logarithmic Triviality of Compact QED Coupled to a Four Fermi Interaction
, 2005 This is the completion of an exploratory study of Compact lattice Quantum Electrodynamics with a weak four-fermi interaction and four species of massless fermions. In this formulation of Quantum Electrodynamics massless fermions can be simulated directly

An Alternative Approach to Spontaneous Photon Triplets Generation
Advanced Physics Research, EarlyView.Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation
Laser &Photonics Reviews, EarlyView.Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

Resurgence in the scalar quantum electrodynamics Euler–Heisenberg Lagrangian
European Physical Journal C: Particles and FieldsWe explore the ideas of resurgence and Padé–Borel resummation in the Euler–Heisenberg Lagrangian of scalar quantum electrodynamics, which has remained largely unexamined in these contexts.

Quantum Limitation to the Coherent Emission of Accelerated Charges
, 2018 Accelerated charges emit electromagnetic radiation. According to classical electrodynamics if the charges move along sufficiently close trajectories they emit coherently, i.e., their emitted energy scales quadratically with their number rather than ...

The vacua of dipolar cavity quantum electrodynamics
, 2020 The structure of solids and their phases is mainly determined by static Coulomb forces while the coupling of charges to the dynamical, i.e., quantized degrees of freedom of the electromagnetic field plays only a secondary role.

Laser &Photonics Reviews, EarlyView.This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...
