Interaction of spin and vibrations in transport through single-molecule magnets

Beilstein Journal of Nanotechnology, 2011
We study electron transport through a single-molecule magnet (SMM) and the interplay of its anisotropic spin with quantized vibrational distortions of the molecule.

Spin Transport in Thin Copper Channels Fabricated via Thermal Scanning Probe Lithography

Advanced Physics Research, EarlyView.
Thermal scanning probe lithography (t‐SPL) is demonstrated as an alternative to electron‐beam lithography for fabricating all‐metallic non‐local spin valves with ∼100 nm features. Devices exhibit strong spin signals and clean magnetic switching, demonstrating the viability of t‐SPL for nanoscale spintronics.

Blocking transport resonances via Kondo many-body entanglement in quantum dots

Nature Communications, 2016
The many-body Kondo effect manifests in low-temperature Coulomb blockaded quantum dots as a zero-bias conductance peak, which arises due to charge-fluctuation-driven transport.

Animal empathy reconsidered: a multidimensional profile account

Biological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Kondo-Zeno crossover in the dynamics of a monitored quantum dot

Nature Communications
Continuously monitoring a quantum system can strongly affect its properties and even suppress its coherent evolution via the Quantum Zeno effect. Here we focus on one of the simplest entangled many-body state, arising via the Kondo effect in a strongly ...

A Convergent Materials Design Paradigm Across Electro‐ and Photocatalysis for Sustainable Hydrogen Peroxide Production

Carbon Energy, EarlyView.
This review outlines advanced modification strategies for electrocatalytic and photocatalytic H2O2 production, covering bandgap tuning, defect engineering, heterostructure construction, cocatalyst loading, and functional framework design. Structure‐performance correlations are revealed across catalysts such as metal oxides, sulfides, carbon nitrides ...

Magnetic properties and spin kinetics in Kondo lattices [PDF]

Magnetic Resonance in Solids, 2015
We present a theoretical model to describe unusual properties of Kondo lattices. The influence of the Kondo effect on the static magnetic susceptibility and electron spin resonance (ESR) parameters is studied in a simple molecular field approximation ...

Observing the universal screening of a Kondo impurity

Nature Communications, 2023
The Kondo effect, deriving from a local magnetic impurity mediating electron-electron interactions, constitutes a flourishing basis for understanding a large variety of intricate many-body problems. Its experimental implementation in tunable circuits has

Two-stage kondo effect in a quantum dot at a high magnetic field [PDF]

, 2002
We report a strong Kondo effect (Kondo temperature ∼4 K) at high magnetic field in a selective area growth semiconductor quantum dot. The Kondo effect is ascribed to a singlet-triplet transition in the ground state of the dot.
