Recently observed Aharonov-Bohm quantum interference of the period h/2e in charge density wave rings strongly suggests that correlated density wave electron transport is a cooperative quantum phenomenon. The picture discussed here posits that quantum solitons nucleate and transport current above a Coulomb blockade threshold field. We propose a field-dependent tunneling matrix element and use the Schrödinger equation, viewed as an emergent classical equation as in Feynman's treatment of… Expand

Quantum fluidic charge density wave transport
We discuss charge density wave transport as the periodic flow of a quantum fluid of electron–phonon correlates, viewed as quantum solitons, within the condensate. Pair creation of charged solitonExpand
The effects of electric and magnetic fields on charge density wave solitons: Possible collective quantum behavior
Aharonov-Bohm oscillations of period h/2e in the charge density wave (CDW) magneto-conductance of TaS3 rings strongly support the hypothesis that CDW electron transport is a cooperative quantumExpand
Quantum mechanisms of density wave transport.
TLDR
In this model, the ratio of electrostatic charging to pinning energy helps determine whether soliton nucleation or classical depinning dominates, and a time-correlated soliton tunneling model is employed to interpret the voltage oscillations and nonlinear current-voltage characteristics above threshold.

Negative resistance state in superconducting NbSe2 induced by surface acoustic waves
TLDR
A negative resistance state is realized in a superconducting gap of NbSe2 by irradiating surface acoustic waves and it is proposed that soliton-antisoliton pairs in the charge density wave of N bSe2 modulated by the SAW serve as a time-dependent capacitance in thesuperconducting state, leading to the dc negative resistance.
