Colored noise probes the topological character of edge modes

Sachiraj Mishra, Colin Benjamin

We investigate colored noise, i.e., finite-frequency noise, as a probe of edge-mode (EM) transport in quantum Hall and quantum spin Hall systems. Colored noise pr…

Noise as a Robust Diagnostic for Chiral, Helical and Trivial Edge Modes

Sachiraj Mishra, Colin Benjamin

In this article, we demonstrate that noise provides a sensitive, practical probe for distinguishing chiral edge modes from topological helical and trivial (non-topological)…

Noise from Electron-Hole Asymmetry in Normal and Superconducting Quantum Point Contacts

Sachiraj Mishra, Colin Benjamin

This work examines noise in two-terminal hybrid nanostructures featuring a quantum point contact (QPC), realized either between two normal metals (NQN) or between a normal m…

Noise in Mesoscopic Hybrid Junctions: Influence of Barrier Strength and Thermal Bias

Sachiraj Mishra, A Rajmohan Dora, Tusaradri Mohapatra +1

Quantum noise is a fundamental probe of quantum transport phenomena, offering insights into current correlations and wave-particle duality. A particularly intriguing form of such n…

Probing the dichotomy between Yu-Shiba-Rusinov and Majorana bound states via conductance, quantum noise and noise

Sachiraj Mishra, Colin Benjamin

We investigate charge and spin conductance, charge and spin quantum noise, along with charge and spin noise, as diagnostic tools to distinguish Yu-Shiba-Rusinov (YSR) states…

Reaching Van den Broeck limit in linear response and Whitney limit in nonlinear response in edge mode quantum thermoelectrics and refrigeration

Sachiraj Mishra, Colin Benjamin

Quantum heat engines and quantum refrigerators are proposed in three-terminal quantum Hall (QH) and quantum spin Hall (QSH) setups with a voltage-temperature probe in both the line…
