Quantum positron acoustic waves
Physics of Plasmas, 2014Nonlinear quantum positron-acoustic (QPA) waves are investigated for the first time, within the theoretical framework of the quantum hydrodynamic model. In the small but finite amplitude limit, both deformed Korteweg-de Vries and generalized Korteweg-de Vries equations governing, respectively, the dynamics of QPA solitary waves and double-layers are ...

ACOUSTIC POLARON IN CYLINDRICAL QUANTUM WIRES
Modern Physics Letters B, 2012The ground state energies and the derivates of the acoustic polaron in cylindrical quantum wire systems are performed by using the Huybrechts-like variational approach. The criterions for presence of the self-trapping transition of the acoustic polaron in cylindrical quantum wires are determined qualitatively.

Quantum mechanical representation of acoustic streaming and acoustic radiation pressure
Physical Review E, 2001We discuss acoustic streaming and acoustic radiation pressure from the viewpoint of energy and momentum of acoustic waves, using a quantum mechanical representation of acoustic waves. We represent the energy epsilon and momentum mu of acoustic waves as epsilon=n(p)homega and mu=n(p)hk; here n(p) is the phonon density, omega is the frequency, k is the ...

Quantum entanglement for acoustic spintronics
Physical Review A, 2004We consider the entanglement of spins for two electrons contributing to the acoustoelectric current driven by a surface acoustic wave (SAW) in two adjacent narrow channels by calculating their exchange energy $(J)$. The channels belong to an acoustic nanocircuit which comprises a network of quasi-one-dimensional pinched-off channels serving as wires ...

Quantum control of acoustic waves
2023A key role in quantum communication technologies is the efficient transport of information between quantum resources (such as spins, superconducting circuits, or light). Typically, one would use microwaves, guided by microwave waveguides, as a transportation mechanism.

Quantum dust-acoustic double layers
Physics of Plasmas, 2007The quantum dust-acoustic double layers (QDADLs) are studied in an unmagnetized, collisionless quantum dusty plasma whose constituents are the electrons, ions, and negatively/positively charged dust particles. By employing the quantum hydrodynamical equations and the reductive perturbation technique, a quantum extended Korteweg–de Vries equation is ...

Coherent Quantum Control of Silicon Vacancy Spins in Diamond with Surface Acoustics
Conference on Lasers and Electro-Optics, 2019We use surface acoustic waves (SAWs)to drive coherent Rabi oscillations of individual silicon vacancy (SiV)spins. Rabi frequencies as high as 48 MHz are obtained with 4 mW total input power. Ramsey interferometry is used to measure a spin coherence of 29

A theoretical scheme is proposed to simulate the quantum phase transitions (QPTs) of the three-level Dicke model. In this designed hybrid system, an ensemble of solid-state spins can simultaneously couple to a superconducting microwave (MW) resonator and

So far all forms of acoustical imaging are diffraction limited and so their resolution limit obeys Rayleigh’s criterion, that is λ/2, where λ is the sound wavelength. In this paper, we apply quantum theory to acoustical imaging and obtain the resolution limit given by the effective de Broglie wavelength λ/N where N is the number of entangled phonons ...
