3 Nov 2003 | Journal: | Phy. Rev. Lett. 92, 056802 (2004) DOI: 10.1103/PhysRevLett.92.056802 | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | Abstract: | We report on the cascade of quantum phase transitions exhibited by tunnel-coupled edge states across a quantum Hall line junction. We identify a series of quantum critical points between successive strong and weak tunneling regimes in the zero-bias conductance. Scaling analysis shows that the conductance near the critical magnetic fields $B_{c}$ is a function of a single scaling argument $|B-B_{c}|T^{-kappa}$, where the exponent $kappa = 0.42$. This puzzling resemblance to a quantum Hall-insulator transition points to importance of interedge correlation between the coupled edge states. | Source: | arXiv, cond-mat/0311022 | Services: | Forum | Review | PDF | Favorites |
