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 ...

Unitary relations in time-dependent harmonic oscillators [PDF]

, 1999
For a harmonic oscillator with time-dependent (positive) mass and frequency, an unitary operator is shown to transform the quantum states of the system to those of a harmonic oscillator system of unit mass and time-dependent frequency, as well as ...

Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy

Advanced Materials, EarlyView.
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Non-KAM classical chaos topology for electrons in superlattice minibands determines the inter-well quantum transition rates

Scientific Reports
We investigate the quantum-classical correspondence for a particle tunnelling through a periodic superlattice structure with an applied bias voltage and an additional tilted harmonic oscillator potential.

Solution of the quantum harmonic oscillator plus a delta-function potential at the origin: The oddness of its even-parity solutions

, 2011
We derive the energy levels associated with the even-parity wave functions of the harmonic oscillator with an additional delta-function potential at the origin.

On the truncation of the harmonic oscillator wavepacket [PDF]

, 2005
We present an interesting result regarding the implication of truncating the wavepacket of the harmonic oscillator. We show that disregarding the non-significant tails of a function which is the superposition of eigenfunctions of the harmonic oscillator ...

Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon‐Enhanced Sum‐Frequency Microscopy

Advanced Materials, EarlyView.
A nonlinear optical microscopy technique is introduced that enables rapid imaging of hexagonal boron nitride monolayers, which are usually optically invisible. The nonlinear mixing of mid‐infrared and visible laser pulses enables full crystallographic imaging through phase‐resolved sum‐frequency generation microscopy, where the resonant excitation of a

Quantum computation with harmonic oscillators [PDF]

Technical Digest. CLEO/Pacific Rim 2001. 4th Pacific Rim Conference on Lasers and Electro-Optics (Cat. No.01TH8557), 2002
Summary form only given. The use of continuous-variable (CV) quantum computing allows information to be encoded and processed much more compactly and efficiently than with discrete-variable (qubit) computing. That is, with CV realizations, one can perform quantum information processes using fewer coupled quantum systems: a considerable advantage for ...
