Spin Seebeck Effect in Normal-Metal--Chiral-Insulator Heterostructure

This paper develops a theoretical framework using nonequilibrium Green's function formalism to study phonon-mediated spin Seebeck effects in normal-metal/chiral-insulator heterostructures, identifying novel nonlinear phenomena such as negative differential SSE and spin-current rectification that could enable thermally controlled spintronic devices.

Finite-size effects in amorphous thin Co70_{70}Zr30_{30} layers

This paper demonstrates that thin Co70Zr30\text{Co}_{70}\text{Zr}_{30} amorphous layers exhibit significant finite-size effects in their magnetic moment and ordering temperature, which are attributed to approximately 1 nm thick interface regions of reduced interaction and the presence of Griffith phases near the critical temperature.

Analytical Treatment of Noise-Suppressed Klein Tunneling in Graphene with Possible Implications for Quantum-Dot Qubits

This paper analytically demonstrates that time-fluctuating potential barriers modeled as Gaussian white noise suppress Klein tunneling in graphene by inducing a complex longitudinal wavevector, offering a method to use noise as a tunable tool for controlling electron transport and designing graphene-based quantum-dot qubits.
