Contribution
It reveals the significant role of spectral flow in dislocation cores for CDW behavior and introduces an analogy with cosmological baryogenesis.
Findings
Spectral flow modifies the hydrodynamic effective action of CDW condensates.
Dislocation core spectral flow impacts charge transport in CDWs.
An analogy between spectral flow in CDWs and baryogenesis is proposed.
Abstract
The spectral flow in the cores of moving dislocations is found to play an important role in the dynamics and transport of charge density wave (CDW) by significantly modifying the hydrodynamic effective action of the condensate. The analogy of spectral flow in CDW with the baryogenesis in the early universe is pointed out.
