Physics of intraband quantum dot optoelectronic devices [PDF]

open access: yes, 2007
In last two decades, semiconductor nanostructures, such as quantum wells, wires and dots, have been recognised as sources and detectors of radiation in the mid- and far-infrared region of the spectrum.

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

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.

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.

Emergence of Supersymmetric Quantum Electrodynamics [PDF]

open access: yesPhysical Review Letters, 2017
Supersymmetric (SUSY) gauge theories such as the Minimal Supersymmetric Standard Model play a fundamental role in modern particle physics, but have not been verified so far in nature. Here, we show that a SUSY gauge theory with dynamical gauge bosons and fermionic gauginos emerges naturally at the pair-density-wave (PDW) quantum phase transition on the
