Imaging the high-frequency charging dynamics of a single impurity in a semiconductor on the atomic scale

This study utilizes MHz-frequency STM noise spectroscopy to reveal that the ionization of individual sulfur donors in InAs is a dynamic, non-equilibrium process driven by local electric fields, characterized by nanosecond-scale charge-state switching and a distinct bias-dependent onset linked to bulk electron interactions.

A Straight Forward Method to Read the Nuclear Qudit of 4f4f Single-Molecule Magnets : 163^{163}DyPc2_2

This paper presents a method to read the nuclear spin state of 163^{163}DyPc2_2 single-molecule magnets using millikelvin spin-polarized scanning tunneling microscopy by analyzing hyperfine-modified telegraph noise statistics and detecting nuclear magnetic resonance directly in the tunneling current, achieving nuclear spin relaxation times exceeding minutes without the need for magnetic field sweeps.

Magnetotransport in the presence of real and momentum space topology

This paper investigates magnetotransport in time-reversal symmetry-broken Weyl semimetals using a semiclassical Boltzmann approach, revealing that the interplay between momentum-space Berry curvature and skyrmion-induced real-space emergent magnetic fields creates distinct strong-and-weak sign-reversal regimes in magnetoconductivity and generates a unique planar Hall response that serves as a measurable signature of real-space topology.
