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…
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…
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…
Majorana fermion induced power-law scaling in the violations of the Wiedemann-Franz law
Sachiraj Mishra, Ritesh Das, Colin Benjamin
Violation of the Wiedemann-Franz law in a 2D topological insulator due to Majorana bound states is studied via the Lorenz ratio in the single-particle picture. We study the scaling…
Negative Spin noise Induced by Spin-Flip Scattering and Andreev Reflection
Sachiraj Mishra, Colin Benjamin
We study charge noise, followed by an examination of spin noise, in the normal metal-spin flipper-normal metal-insulator-superconductor (N-sf-N-I-S) junction. Our analy…
Majorana Thermoelectrics and Refrigeration
Sachiraj Mishra, Ritesh Das, Colin Benjamin
A two-terminal quantum spin-Hall heat engine and refrigerator with embedded Majorana bound states (MBS) is analyzed for optimality in thermoelectric performance using the Landaeur-…
Finite temperature quantum noise correlations as a probe for topological helical edge modes
Sachiraj Mishra, Colin Benjamin
The distinction between chiral, trivial helical, and topological helical edge modes can be effectively made using quantum noise measurements at finite temperatures. Quantum noise m…
