Electromagnetic fields with vanishing quantum corrections

open access: yesPhysics Letters B, 2018
We show that a large class of null electromagnetic fields are immune to any modifications of Maxwell's equations in the form of arbitrary powers and derivatives of the field strength.

Monopoles, Clarified

open access: yesFortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Quantum electrodynamics with magnetic textures

open access: yesNew Journal of Physics, 2019
Coherent exchange between photons and different matter excitations (like qubits, acoustic surface waves or spins) allows for the entanglement of light and matter and provides a toolbox for performing fundamental quantum physics.

Charged gravitational instantons: extra CP violation and charge quantisation in the Standard Model

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We argue that quantum electrodynamics combined with quantum gravity results in a new source of CP violation, anomalous non-conservation of chiral charge and quantisation of electric charge.

Accelerated Characterization of Two‐Level Systems in Superconducting Qubits Via Machine Learning

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
We introduce a data‐driven approach for extracting two‐level system (TLS) parameters–frequency ωTLS$\omega _{\text{TLS}}$, coupling strength g$g$, dissipation time TTLS,1$T_{\text{TLS}, 1}$, and the pure dephasing time TTLS,2φ$T^\varphi _{\text{TLS}, 2}$, labeled as a 4 component vector q⃗$\vec{q}$, directly from simulated spectroscopy data generated ...
