Exclusion Statistics as a Thermodynamic Resource in Quantum Heat Engines
Sampurna Karmakar, Aziz Hasan, Sourin Das
The maximum power extractable from a quantum thermoelectric heat engine operating with free fermion carriers is bounded by the universal Whitney limit, $P_{\text{fermion}}^{\max} \…
Elevated Hall Responses as Indicators of Edge Reconstruction
Sampurna Karmakar, Amulya Ratnakar, Sourin Das
We investigate edge reconstruction scenarios in the quantum Hall state, focusing on configurations with upstream and downstream charge and neutral modes. Our analysis shows…
Dynamic enhancement of conductance in fractional quantum Hall constriction
Sampurna Karmakar, Amulya Ratnakar, Sourin Das
A disparity in the charge of quasi-particle excitations across a tunnel junction can trigger Andreev-like processes, creating an effect similar to that of a step-up transformer. We…
Statistical Interaction Driven Thermoelectricity and Violation of Wiedemann-Franz Law
Sampurna Karmakar, Amulya Ratnakar, Sourin Das
Quantum transport anomalies in systems obeying Haldane-Wu fractional exclusion statistics, characterized by the statistical interactions parameter are investigated. We identify…
