Isolated Ballistic Non-Abelian Interface Channel
Bivas Dutta, Vladimir Umansky, Mitali Banerjee +1
Non-abelian anyons are prospective candidates for fault-tolerant topological quantum computation due to their long-range entanglement. Curiously these quasiparticles are charge-neu…
Absent thermal equilibration on fractional quantum Hall edges over macroscopic scale
Ron Aharon Melcer, Bivas Dutta, Christian Spånslätt +3
Two-dimensional topological insulators, and in particular quantum Hall states, are characterized by an insulating bulk and a conducting edge. Fractional states may host both downst…
Novel method distinguishing between competing topological orders
Bivas Dutta, Wenmin Yang, Ron Aharon Melcer +6
Quantum Hall states - the progenitors of the growing family of topological insulators -- are rich source of exotic quantum phases. The nature of these states is reflected in the ga…
Non-Linear Thermovoltage in a Single-Electron Transistor
Paolo A. Erdman, Joonas T. Peltonen, Bibek Bhandari +5
We perform direct thermovoltage measurements in a single-electron transistor, using on-chip local thermometers, both in the linear and non-linear regimes. Using a model which accou…
Direct measurement of the Seebeck coefficient in a Kondo-correlated single-quantum-dot transistor
B. Dutta, D. Majidi, A. Garcia Corral +5
We report on the first measurement of the Seebeck coefficient in a tunnel-contacted and gate-tunable individual single-quantum dot junction in the Kondo regime, fabricated using th…
Thermal Conductance of a Single-Electron Transistor
B. Dutta, J. T. Peltonen, D. S. Antonenko +7
We report on combined measurements of heat and charge transport through a single-electron transistor. The device acts as a heat switch actuated by the voltage applied on the gate.…
