Four-nucleon shell-model calculations in a Faddeev-like approach [PDF]
, 1998 We use equations for Faddeev amplitudes to solve the shell-model problem for four nucleons in the model space that includes up to 14 hbar Omega harmonic-oscillator excitations above the unperturbed ground state. Two- and three-body effective interactions

Anti-PT-symmetric harmonic oscillator and its relation to the inverted harmonic oscillator [PDF]
arXiv, 2022 We treat the quantum dynamics of a harmonic oscillator as well as its inverted counterpart in the Schr\"odinger picture. Generally in the most papers of the literature, the inverted harmonic oscillator is formally obtained from the harmonic oscillator by the replacement of {\omega} to i{\omega}, this leads to unbounded eigenvectors.

Inverted oscillator: pseudo hermiticity and coherent states [PDF]
arXiv, 2022 It is known that the standard and the inverted harmonic oscillator are different. Replacing thus of {\omega} by i{\omega} in the regular oscillator is necessary going to give the inverted oscillator H^{r}. This replacement would lead to anti- PT-symmetric harmonic oscillator Hamiltonian (iH^{os}).

Relativistic Harmonic Oscillator with Spin Symmetry
, 2005 The eigenfunctions and eigenenergies for a Dirac Hamiltonian with equal scalar and vector harmonic oscillator potentials are derived. Equal scalar and vector potentials may be applicable to the spectrum of an antinucleion imbedded in a nucleus. Triaxial,

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

First harmonic injection locking of 24-GHz-oscillators [PDF]
Advances in Radio Science, 2003 An increasing number of applications is proposed for the 24 GHz ISM-band, like automotive radar systems and short-range communication links. These applications demand for oscillators providing moderate output power of a few mW and moderate frequency ...

Discrete time model of self-oscillations with spectral line widening
Физика волновых процессов и радиотехнические системы, 2022 An algorithm for generating quasi-harmonic self-oscillations with a uniformly widened spectral line is presented. The algorithm is based on the equation of motion of the Thomson-type DT-oscillator, which introduced a random effect in the form of band ...

Equivalence of quantum harmonic oscillators and classical oscillators subject to random forces [PDF]
arXiv, 2020 We show that the Schr\"{o}dinger equation for the quantum harmonic oscillator can be derived as an approximation to the Newtonian mechanics of a classical harmonic oscillator subject to a random force for time intervals $O( m / \hbar)$, when $\hbar / m \ll 1$.

Advanced Functional Materials, EarlyView.An ultrathin polarizonic metasurface achieves multiband camouflage and stealth with near‐perfect ultraviolet (UV) absorption, visible light blending, and infrared signature masking. Leveraging earth‐abundant materials, this design creates a reflective color palette through polarizonic effects, integrating transparent and non‐plasmonic materials.
