Fractional Conductance in One-Dimensional Constrictions

Explore the intriguing world of fractional conductance in one-dimensional systems through this comprehensive 1-hour and 26-minute lecture by Igor Yurkevich from the PCS Institute for Basic Science. Delve into recent experimental findings on transport in one-dimensional constrictions, which have revealed conductance plateaus corresponding to various fractions of the conductance quantum when fine-tuning the conducting channel. Examine the latest theoretical models proposed to explain these observations and engage in thought-provoking discussions on the potential fractions that can be expected within the framework of the Luttinger model approach. Gain valuable insights into this cutting-edge research area and its implications for our understanding of quantum transport phenomena in low-dimensional systems.
