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} \…
Enhanced Andreev Reflection in Flat-Band Systems: Wave Packet Dynamics, DC Transport and the Josephson Effect
Sarbajit Mazumdar, Anamitra Mukherjee, Kush Saha +1
We investigate Andreev reflection (AR) in a proximity-induced normal-superconductor (NS) junction within the extended lattice, emphasizing the impact of flat band…
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…
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…
Anisotropic magneto-photothermal voltage in Sb2Te3 topological insulator thin films
Subhadip Manna, Sambhu G Nath, Samrat Roy +8
We studied longitudinal and Hall photothermal voltages under a planar magnetic field scan in epitaxial thin films of the Topological Insulator (TI) Sb2Te3, grown using pulsed laser…
