Quantum Electrodynamics in a Topological Waveguide [PDF]

Physical Review X, 2020
While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic bath itself.

Quasiperiodic circuit quantum electrodynamics

npj Quantum Information, 2023
Superconducting circuits are an extremely versatile platform to realize quantum information hardware and to emulate topological materials. We here show how a simple arrangement of capacitors and conventional superconductor-insulator-superconductor ...

Visualizing the emission of a single photon with frequency and time resolved spectroscopy [PDF]

Quantum, 2021
At the dawn of Quantum Physics, Wigner and Weisskopf obtained a full analytical description (a $\textit{photon portrait}$) of the emission of a single photon by a two-level system, using the basis of frequency modes (Weisskopf and Wigner, "Zeitschrift ...

Resolution of Gauge Ambiguities in Molecular Cavity Quantum Electrodynamics. [PDF]

Physical Review Letters, 2020
This work provides the fundamental theoretical framework for molecular cavity quantum electrodynamics by resolving the gauge ambiguities between the Coulomb gauge and the dipole gauge Hamiltonians under the electronic state truncation. We conjecture that

Seamless High-Q Microwave Cavities for Multimode Circuit Quantum Electrodynamics. [PDF]

Physical Review Letters, 2020
Multimode cavity quantum electrodynamics-where a two-level system interacts simultaneously with many cavity modes-provides a versatile framework for quantum information processing and quantum optics. Because of the combination of long coherence times and

Quantum Spacetime Geometrization: QED at High Curvature and Direct Formation of Supermassive Black Holes from the Big Bang

Quantum Reports, 2023
In this work, the author employs the quantum hydrodynamic formalism to achieve the geometrization of spacetime for describing the gravitational interaction within the framework of quantum theory. This approach allows for the development of an equation of

Mark Burgin’s Contribution to the Foundation of Mathematics

Philosophies, 2023
In this paper, I attempt to describe Mark Burgin’s results in non-Diophantine mathematics, which are important for the foundation of mathematics and its application in quantum field theory.

Quantum electrodynamics in finite volume and nonrelativistic effective field theories

Physics Letters B, 2016
Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativistic

Quantum bath engineering of a high impedance microwave mode through quasiparticle tunneling

Nature Communications, 2022
Quantum bath engineering in the context of circuit quantum electrodynamics typically relies on single-photon losses. Aiello et al. demonstrate an approach for engineering higher-order photon losses in a microwave resonator coupled to a tunnel junction ...
