Some new features of photon statistics in a fully quantized parametric amplification process
(Scientific Research Publishing, 2014)
An exact quantum treatment reveals that signal and idler photon number operators are not wellbehaved dynamical operators for studying photon statistics in parametric amplification/downconversion processes. Contrary to ...
heoretical Realization of a Two Qubit Quantum Controlled-NOT Logic Gate and a Single Qubit Quantum Hadamard Logic Gate in the Anti-Jaynes-Cummings Mode
(ResearchGate, 2021)
The interactive and cumulative effect of temperature and rainfall on land cover change is a priority at global, regional and local scale. This study examined changes in six land cover categories (forestland, grasslands, ...
Fundamental quantum noise in a fully quantized degenerate parametric amplification process
(Research gate, 2016)
An exact analytical solution of the time-dependent Schroedinger equation for a fully quantized
degenerate parametric amplification process generated by quantized multi-mode pump photons
provides a quantized multi-photon ...
A note on momentum and energy conservation in dynamics under arbitrary forces in classical Newtonian and relativistic mechanics
(Research gate, 2018)
In teaching mechanics course to first year undergraduate students, I have come across a simple, but very important, gap in the formulation of the principle of conservation of momentum and energy in the dynamics of a body ...
Revisiting non-degenerate parametric down-conversion
(Springer-Verlag, 2008)
he quantum dynamics of a two-mode non-resonant parametric down-conversion process is studied by recasting the time evolution equations for the basic operators in an equivalent spin equation form with simpler exact solutions ...
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Cornell University, 2021)
In this article we apply algebraic operator ordering property of the basic atom and field operators to construct and prove conservation of the excitation number operator of the anti-rotating (anti-Jaynes-Cummings) component ...
Complex Spacetime Frame: Four-Vector Identities and Tensors
(Scientific Research Publishing, 2014)
This paper provides derivation of some basic identities for complex four-component vectors defined in a complex four-dimensional spacetime frame specified by an imaginary temporal axis.
The resulting four-vector identities ...
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Cornell University, 2021)
In this article we apply algebraic operator ordering property of the basic atom and field operators to construct and prove conservation of the excitation number operator of the anti-rotating (anti-Jaynes-Cummings) component ...
Exact analytical solutions for fully quantized parametric oscillation dynamics
(Routledge, 2013)
In this paper, a simple method for obtaining general analytical solutions of the time evolution equations for a fully quantized parametric oscillation process is developed. Heisenberg’s equations for the signal–idler photon ...
Polariton and anti-polariton qubits in the Rabi model
(Research gate, 2017)
This paper presents a precise algebraic and physical framework for studying the dynamics and practical
applications of the quantum Rabi model. We redefine the quantum Rabi interaction in terms of polariton
and anti-polariton ...
