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…
Temperature-Bias Noise and Quantum Shot Noise as Probes of Pairing Symmetry in Iron Pnictides
Sachiraj Mishra, A Rajmohan Dora, Colin Benjamin
Quantum noise has long served as a powerful probe of quantum transport in mesoscopic junctions. Recently, temperature-driven noise, or noise, has attracted growing interest d…
Effect of electron-hole asymmetry on noise in metal/quantum point contact/metal and metal/quantum point contact/superconductor junctions
Sachiraj Mishra, Colin Benjamin
This work examines charge noise in two-terminal hybrid nanostructures featuring a quantum point contact (QPC), realized either between two normal metallic leads (NQN) or betw…
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) h…
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…
