We describe the edge states of fractional quantum Hall systems with alternating compressible and incompressible strips using a composite-fermion picture. The current carried by composite fermions in a compressible region depends on the difference between the electron filling factors in the two adjacent incompressible regions, consistent with the results of the interacting-electron picture given by Beenakker [Phys. Rev. Lett. 64, 216 (1990)] and tested by recent experiments. This result allows the application of the Landauer-Büttiker formula for the composite fermion transport.

Heating up of Superconductors
January 27, 2017

This collection marks the 30th anniversary of the discovery of high-temperature superconductors. The papers selected highlight some of the advances that have been made to date, both in understanding why these compounds behave in the way they do, and in utilizing them in applications. The papers included in the collection have been made free to read.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
