Atomic-waveguide quantum electrodynamics

open access: yesPhysical Review Research, 2020
Atom arrays are a new type of quantum light-matter interface. Here we propose to employ one-dimensional ordered arrays as atomic waveguides. These arrays support optical guided modes that do not decay into free space.

Nonperturbative waveguide quantum electrodynamics

open access: yesPhysical Review Research, 2022
Understanding physical properties of quantum emitters strongly interacting with quantized electromagnetic modes is one of the primary goals in the emergent field of waveguide quantum electrodynamics (QED).

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

open access: yesQuantum, 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 ...

Quasiperiodic circuit quantum electrodynamics

open access: yesnpj 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 ...

Cavity quantum electrodynamics with color centers in diamond [PDF]

open access: yes, 2020
Coherent interfaces between optical photons and long-lived matter qubits form a key resource for a broad range of quantum technologies. Cavity quantum electrodynamics (cQED) offers a route to achieve such an interface by enhancing interactions between ...

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

open access: yesQuantum 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

Algebraic Structures in the Coupling of Gravity to Gauge Theories

open access: yes, 2020
This article is an extension of the author's second master thesis [1]. It aims to introduce to the theory of perturbatively quantized General Relativity coupled to Spinor Electrodynamics, provide the results thereof and set the notation to serve as a ...

Unitarity of theories containing fractional powers of the d'Alembertian operator [PDF]

open access: yes, 2014
We examine the unitarity of a class of generalized Maxwell U(1) gauge theories in (2+1) D containing the pseudodifferential operator $\Box^{1-\alpha}$, for $\alpha \in [0,1)$.

Quantum Electrodynamics in a Topological Waveguide [PDF]

open access: yesPhysical 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.
