Disordered contacts can localize chiral edge electrons
Arjun Mani, Colin Benjamin
Chiral integer quantum Hall (QH) edge modes are immune to backscattering and therefore are non-localized and show a vanishing longitudinal as well as non-local resistance along wit…

Optimal quantum refrigeration in strained graphene
Arjun Mani, Colin Benjamin
Refrigerators soak up heat energy from a low-temperature region and dump it into a higher temperature region using external work done on the system. Refrigerators are useful in coo…

Are thermal fluctuations the sole reason for finite longitudinal resistance in quantum anomalous Hall experiments?
Arjun Mani, Colin Benjamin
In some recent experiments [A. J. Bestwick, et. al., Phys. Rev. Lett. 114, 187201 (2015), Cui-Zu Chang, et. al., Nat. Materials. 14, 473-477 (2015)] it has been shown that in obser…
