Effect of electric and magnetic field on thermal property of two dimensional harmonic oscillator
Results in Physics, 2023 The energy spectrum of a 2D quantum harmonic oscillator confined by a hard wall circular cavity of size r0 in the presence of static electric and the magnetic field is computed numerically using the Bessel function basis set and the linear variational ...

Quantum versus Semiclassical Description of Selftrapping: Anharmonic Effects
, 1999 Selftrapping has been traditionally studied on the assumption that quasiparticles interact with harmonic phonons and that this interaction is linear in the displacement of the phonon.

A Wigner distribution function for finite oscillator systems [PDF]
, 2013 We define a Wigner distribution function for a one-dimensional finite quantum system, in which the position and momentum operators have a finite (multiplicity-free) spectrum. The distribution function is thus defined on discrete phase-space, i.e.

Duality in the quantum harmonic oscillator
Journal of Physics A: Mathematical and General, 2001 Summary: We show that any abstract creation (or annihilation) operator is in duality with the finite difference one acting in \(\ell^2\). This duality relation is generic and its spatial character allows both agents to be identified within the class of weighted shifts.

The Quantum Harmonic Oscillator in the ESR Model [PDF]
Foundations of Physics, 2013 The ESR model proposes a new theoretical perspective which incorporates the mathematical formalism of standard (Hilbert space) quantum mechanics (QM) in a noncontextual framework, reinterpreting quantum probabilities as conditional on detection instead of absolute.

Nonlinear Optical Properties of Mono and Multilayer MoWSe2 Alloys
Advanced Optical Materials, EarlyView.We employ second‐harmonic generation and two‐photon photoluminescence to probe the excitonic resonances and exciton binding energy in Mo(1x)WxSe2 alloys as a function of composition and layer number. Our work lays the groundwork for understanding the optical and electronic properties of TMD alloys, a crucial step toward next‐generation optoelectronic ...

Carbon Dioxide Capture and Functionalization from a Molecular Ti(III) Oxo Anion
Angewandte Chemie, EarlyView.In their communication, Mindiola and coworkers demonstrate how a reduced Ti complex can reversibly bind CO2 to produce organic and inorganic carbonates. They access this chemistry through a unique TiIII oxo anion that can be generated both chemically and electrochemically.

Quantization, group contraction and zero point energy [PDF]
, 2002 We study algebraic structures underlying 't Hooft's construction relating classical systems with the quantum harmonic oscillator. The role of group contraction is discussed.
