Ballistic-to-diffusive transition in engineered counter-propagating quantum Hall channels
Aifei Zhang, Kenji Watanabe, Takashi Taniguchi +4
Exotic quantum Hall systems hosting counter-propagating edge states can show seemingly non-universal transport regimes, usually depending on the size of the sample. We experimental…
Quantized heat flow in the Hofstadter butterfly
Aifei Zhang, Gibril Aissani, Quan Dong +11
When subjected to a strong magnetic field, electrons on a two-dimensional lattice acquire a fractal energy spectrum called Hofstadter's butterfly. In addition to its unique recursi…
Non-ohmic to ohmic crossover in the breakdown of the quantum Hall states in graphene under broadband excitations
Torsten Röper, Aifei Zhang, Kenji Watanabe +4
Graphene, through the coexistence of large cyclotron gaps and small spin and valley gaps, offers the possibility to study the breakdown of the quantum Hall effect across a wide ran…
Non-universal localization transition in the quantum Hall effect probed through broken-symmetry states of graphene
Aifei Zhang, Torsten Röper, Manjari Garg +7
The quantum Hall effect hosts quantum phase transitions in which the localization length, that is the size of disorder-induced bulk localized states, is governed by universal scali…
Vanishing bulk heat flow in the nu=0 quantum Hall ferromagnet in monolayer graphene
Raphaëlle Delagrange, Manjari Garg, Gaëlle Le Breton +9
Under high perpendicular magnetic field and at low temperatures, graphene develops an insulating state at the charge neutrality point. This state, dubbed , is due to the inte…
