On The Harmonic Oscillator Group [PDF]
, 2011 We discuss the maximum kinematical invariance group of the quantum harmonic oscillator from a view point of the Ermakov-type system. A six parameter family of the square integrable oscillator wave functions, which seems cannot be obtained by the standard

Phase operator of the quantum supersymmetric harmonic oscillator [PDF]
arXiv, 2007 After a brief introduction recalling how, in the limit in which the mass and the electric charge of the electron and the positron tend to zero, Quantum Electrodynamics reduces to a collection of uncoupled quantum supersymmetric harmonic oscillators, the phase operator of the quantum fermionic harmonic oscillator and of the quantum supersymmetric ...

Advanced Theory and Simulations, EarlyView.This study analyses the electronic structure of five‐electron spherical quantum dots with penetrable confinement potential. Spatial confinement and the influence of potential barrier height give rise to the unique properties of quantum dots. These effects lead to profound changes in their energy spectra and optical properties which play a key role in ...

Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses
Physical Review ResearchWe propose and demonstrate the concept of hybrid coherent control (CC) whereby a quantum or classical harmonic oscillator is excited by two excitations: one is quasiharmonic (i.e., harmonic with a finite lifetime) and the other is a pulsed broadband ...

Relativistic Ladder Operators for the Three-Dimensional Harmonic Oscillator [PDF]
arXiv, 2009 The quantum constraint equations for a relativistic three-dimensional harmonic oscillator are shown to find concise expression in terms of Lorentz covariant ladder operators. These ladder operators consist of two conjugate 4-vectors that are each constrained to generate three linearly independent combinations of ladder operator components for raising ...

Advanced Science, EarlyView.Through the one‐pot interface‐enhanced selenization and self‐guided growth method, wafer‐scale HfSe2/WSe2 interlayer heterostructures with vertically aligned van der Waals layers are fabricated. The resulting heterostructures, characterized by covalent bonds, demonstrate significant charge transfer, enhanced piezoelectricity, notable rectification ...

Endocrinology, Diabetes &Metabolism, Volume 6, Issue 1, January 2023., 2023 Infrared detection by thermal camera obeys Stefan's law of radiative heat transfer. This associated uncertainty in detection is estimated by the formula of propagation of error. Abstract Brown adipose tissue (BAT) represents a pivotal scientific renaissance worthy as a strategy for obesity and diabetes since its re‐discovery in adults over a decade ago.
