ON THE HEISENBERC PICTURE IN QUANTUM ELECTRODYNAMICS [PDF]
Acta Physica Sinica, 1945 The form of quantum theory of reaiation introdnced by Heiaonbarg is diarnaaed from the point of view of the transformation theory of quantum electrodynamics.A general investigation of the connection between Heisenberg's method and Dirac'smethod of variation of parameters is given.The exetension of Heisenberg's methodto eigenvalue problems.which was ...

Easy-plane QED3’s in the large N f limit
Journal of High Energy Physics, 2019 We consider Quantum Electrodynamics in 2 + 1 dimensions with N f fermionic or bosonic flavors, allowing for interactions that respect the global symmetry U(N f /2)2. There are four bosonic and four fermionic fixed points, which we analyze using the large

Time-Dependent Effective Hamiltonians for Light–Matter Interactions
EntropyIn this paper, we present a systematic approach to building useful time-dependent effective Hamiltonians in molecular quantum electrodynamics. The method is based on considering part of the system as an open quantum system and choosing a convenient ...

Experimentally simulating the dynamics of quantum light and matter at deep-strong coupling
Nature Communications, 2017 Realising deep-strong coupling phenomena for interacting light-matter systems remains an experimental challenge. Here, Langford et al. employ a circuit quantum electrodynamics chip with moderate coupling between a resonator and transmon qubit to realise ...

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.

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.
