Recent experiments show oscillations of dominant period h/2e in conductance vs. magnetic flux of charge density wave (CDW) rings above 77 K, revealing macroscopically observable quantum behavior. The time-correlated soliton tunneling model discussed here is based on coherent, Josephson-like tunneling of microscopic quantum solitons of charge 2e. The model interprets the CDW threshold electric field as a Coulomb blockade threshold for soliton pair creation, often much smaller than the classical… Expand

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 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
Transmission time and resonant tunneling through barriers using localized quantum density soliton waves
In this paper, the interaction and transmission time of quantum density solitons waves [B. M. Mirza, Mod. Phys. Lett. B 28 (2014) 1450200]1 passing through finite barrier potentials is investigated.Expand
Charge density wave soliton liquid
We investigate the charge density wave transport in a quasi-one-dimensional conductor, orthorhombic tantalum trisulfide ($o$-TaS$_3$), by applying a radio-frequency ac voltage. We find a new ac-dcExpand
Time-Correlated Vortex Tunneling in Layered Superconductors
The nucleation and dynamics of Josephson and Abrikosov vortices determine the critical currents of layered high-Tc superconducting (HTS) thin films, grain boundaries, and coated conductors, soExpand
Controlling the metal-to-insulator relaxation of the metastable hidden quantum state in 1T-TaS2
The metastable state relaxation rate may be externally stabilized by substrate strain, thus opening the way to the design of nonvolatile ultrafast high-temperature memory devices based on switching between CDW states with large intrinsic differences in electrical resistance. Expand
Single-valuedness problem on charge density wave rings
We investigate the bimodal fluctuation of charge density wave (CDW) current through ring-shaped crystals (typical diameter is a few ten ) of orthorhombic tantalum trisulfide . We find that the CDWExpand
Quantum Transport in the Markovian and Non-Markovian Environment
In this paper, we report on a detailed study of how decoherence assists quantum transport in a dimer system. By carrying out analytical and numerical computations, we find that the decoherenceExpand
Field-induced dielectric response saturation in o-TaS3.
With a decrease in temperature, the effect of external field on the dielectric response of the system weakens gradually and at 13 K it diminishes due to soliton freezing, and the possible reasons may be related to the polarization behavior of charged solitons. Expand
