Density Profiles, Energy, and Oscillation Strength of a Quantum Dot in Two Dimensions with a Harmonic Oscillator External Potential using an Orbital-free Energy Functional Based on Thomas–Fermi Theory

open access: yesMakara Journal of Science, 2016
This research aims i) to determine the density profile and calculate the ground state energy of a quantum dot in two dimensions (2D) with a harmonic oscillator potential using orbital-free density functional theory, and ii) to understand the effect of ...

High-fidelity quantum information transmission using a room-temperature nonrefrigerated lossy microwave waveguide

open access: yesScientific Reports, 2022
Quantum microwave transmission is key to realizing modular superconducting quantum computers and distributed quantum networks. A large number of incoherent photons are thermally generated within the microwave frequency spectrum.

Exact diagonalization of the D-dimensional spatially confined quantum harmonic oscillator [PDF]

open access: yesKragujevac Journal of Science, 2016
In the existing literature various numerical techniques have been developed to quantize the confined harmonic oscillator in higher dimensions. In obtaining the energy eigenvalues, such methods often involve indirect approaches such as searching for the ...

Quantum Harmonic Oscillator Systems with Disorder [PDF]

open access: yesJournal of Statistical Physics, 2012
We study many-body properties of quantum harmonic oscillator lattices with disorder. A sufficient condition for dynamical localization, expressed as a zero-velocity Lieb-Robinson bound, is formulated in terms of the decay of the eigenfunction correlators for an effective one-particle Hamiltonian.

Semiclassical superoscillations: interference, evanescence, post-WKB

open access: yesNew Journal of Physics, 2021
The concept of superoscillations is extended beyond bandlimited functions, to include monochromatic waves in space-varying media, such as wavefunctions representing quantum particles in non-constant potentials.

Quantum Harmonic Oscillator

open access: yes, 2019
The story of quantum physics began in 1900 when Max Planck discovered by the thermodynamical methods the improvement of the Wien’s law of energy distribution for blackbody radiation and then formulated the microscopic derivation of his equation in terms of oscillators within the cavity of a blackbody.

Modelling of q-deformed harmonic oscilator on quantum computer [PDF]

open access: yesarXiv, 2023
We present a method of a quantum simulation of a quantum harmonic oscillator in a special case of the deformed commutation relation, which corresponds to the so-called q-deformed oscillator on an IBM quantum computer. Using the method of detection of energy levels of a spin system on a quantum computer by probe spin evolution we obtain the energy ...
