Enhanced Electron Reflection at Mott‐Insulator Interfaces
Annalen der Physik, Volume 538, Issue 6, June 2026.A condensed‐matter analog of the Klein paradox is demonstrated at a Mott‐insulator‐semiconductor interface. Using the hierarchy of correlations, Schrödinger‐like equations for doublons and holons as well as boundary conditions are derived. For incident energies below mid‐gap, the interface exhibits anomalous reflection probabilities exceeding unity ...

To B or not to B: primordial magnetic fields from Weyl anomaly
Journal of High Energy Physics, 2018 The quantum effective action for the electromagnetic field in an expanding universe has an anomalous dependence on the scale factor of the metric arising from virtual charged particles in the loops.

Interaction Induced Quantum Valley Hall Effect in Graphene
Physical Review X, 2015 We use pseudo-quantum electrodynamics in order to describe the full electromagnetic interaction of the p electrons in graphene in a consistent 2D formulation.

Transverse recoil imprinted on free-electron radiation
Nature CommunicationsPhenomena of free-electron X-ray radiation are treated almost exclusively with classical electrodynamics, despite the intrinsic interaction being that of quantum electrodynamics. The lack of quantumness arises from the vast disparity between the electron

Designing Kerr interactions using multiple superconducting qubit types in a single circuit
New Journal of Physics, 2018 The engineering of Kerr interactions is of great interest for processing quantum information in multipartite quantum systems and for investigating many-body physics in a complex cavity-qubit network.

Electromagnetic fields with vanishing quantum corrections
Physics 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.

Quantum electrodynamics with magnetic textures
New 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
European 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.

Gauge interactions and the Galilean limit
European Physical Journal C: Particles and FieldsThe gauge invariant minimal couplings for a class of relativistic free matter fields with global symmetry (related to usual charge conservation) have been obtained by incorporating an iterative Noether mechanism. Non-relativistic reduction of both matter

Resolution of superluminal signalling in non-perturbative cavity quantum electrodynamics
Nature Communications, 2018 Quantum Rabi model is a standard tool for describing cavity quantum electrodynamics, but the potential shortcomings of its single-mode version are usually neglected.
