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

Mark Burgin’s Contribution to the Foundation of Mathematics

open access: yesPhilosophies, 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

open access: yesPhysics 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

open access: yesNature 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 ...

No drama quantum electrodynamics? [PDF]

open access: yesThe European Physical Journal C, 2013
This article builds on recent work (A. Akhmeteli, Int'l Journ. of Quantum Information, vol. 9, Suppl. (2011) p. 17, and A. Akhmeteli, Journ. Math. Phys., vol. 52 (2011) p. 082303), providing a theory that is based on spinor electrodynamics, is described by a system of partial differential equations in 3+1 dimensions, but reproduces unitary evolution of

Cosmological birefringence and the geometric phase of photons

open access: yesPhysics Letters B, 2019
Regarding axion electrodynamics in the background flat FRW universe, we show that cosmological birefringence arises from an adiabatic noncyclic geometric phase that appears in the quantum state of photons because of their interaction with the axion field.

Coupling quantum emitters in metal–insulator–metal heterostructure: Green tensor approach in the quasi-static limit

open access: yesAIP Advances, 2022
Coupling between quantum emitters (QEs) has been a topic extensively explored in recent years. Theoretical models based on the Lindblad master equation and mapping to cascaded quantum system has shed light to the chiral coupling phenomena from the aspect

Polaritonics: from microcavities to sub-wavelength confinement

open access: yesNanophotonics, 2019
Following the initial success of cavity quantum electrodynamics in atomic systems, strong coupling between light and matter excitations is now achieved in several solid-state set-ups.
