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 ...

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.

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 $\alpha \in [0,1)$.

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.

The Importance of Boundary Conditions in Quantum Mechanics [PDF]

open access: yes, 2003
We discuss the role of boundary conditions in determining the physical content of the solutions of the Schrodinger equation. We study the standing-wave, the ``in,'' the ``out,'' and the purely outgoing boundary conditions. As well, we rephrase Feynman's $
