Quantum Increase of a Soliton Width Due to Squeezed Coherent Phonons
نویسنده
چکیده
ABSTRACT: Correlation of squeezing and displacement variational parameters of phonons is shown to enhance the e ective electron-phonon coupling constant when compared with the uncorrelated case. The correlation supresses all quantum e ects of phonons: the quantum reduction of the polaron sel ocalization, of the Debye-Waller factor and of the increase of the soliton (quantum Holstein polaron) width due to quantum uctuations.

Quantum phonon optics: Coherent and squeezed atomic displacements.
We investigate coherent and squeezed quantum states of phonons. The latter allow the possibility of modulating the quantum fluctuations of atomic displacements below the zero-point quantum noise level of coherent states. The expectation values and quantum fluctuations of both the atomic displacement and the lattice amplitude operators are calculated in these states—in some cases analytically. W...

The propagation of nonlinear quantum dust ion-acoustic (QDIA) solitary waves in a unmagnetized quantum plasma whose constituents are inertialess quantum electrons and positrons, classical cold ions and stationary negative dust grains are studied by deriving the Korteweg–de Vries (KdV) equation under the reductive perturbation method. Quantum Hydrodynamic (QHD) equations are used to take into ...

We study squeezed quantum states of phonons, which allow the possibility of modulating the quantum fluctuations of atomic displacements below the zero-point quantum noise level of coherent phonon states. We calculate the corresponding expectation values and fluctuations of both the atomic displacement and lattice amplitude operators, and also investigate the possibility of generating squeezed p...

متن کاملPhonon Squeezed States Generated by Second-Order Raman Scattering
We study squeezed states of phonons, which allow a reduction in the quantum fluctuations of the atomic displacements to below the zero-point quantum noise level of coherent phonon states. We investigate the generation of squeezed phonon states using a second-order Raman scattering process. We calculate the expectation values and fluctuations of both the atomic displacement and the lattice ampli...
