Spectroscopic Evidence for the Localization of Skyrmions near Nu=1 as T->0 [PDF]

open access: yes, 2002
Optically pumped nuclear magnetic resonance measurements of Ga-71 spectra were carried out in an n-doped GaAs/Al0.1Ga0.9As multiple quantum well sample near the integer quantum Hall ground state Nu=1.

In‐Situ Solution Complexation for n‐Type Surface‐Energetics Reconstruction in 2.0 eV Ultra‐Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Fractional Chern Insulator

open access: yesPhysical Review X, 2011
Chern insulators are band insulators exhibiting a nonzero Hall conductance but preserving the lattice translational symmetry. We conclusively show that a partially filled Chern insulator at 1/3 filling exhibits a fractional quantum Hall effect and rule ...

The manifesto as genre in Ibsen's John Gabriel Borkman

open access: yesNordlit: Tidsskrift i litteratur og kultur, 2015
This article examines John Gabriel Borkman’s neo-aristocratic performance of power and authority in Ibsen’s eponymously titled play (1896). After his downfall, John Gabriel has retreated into his once grand reception hall wherein he has become like a ...

Three-point density correlation functions in the fractional quantum Hall regime

open access: yes, 2000
In this paper we consider the three-particle density correlation function for a fractional quantum Hall liquid. The study of this object is motivated by recent experimental studies of fractional quantum Hall systems using inelastic light scattering and ...

Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation

open access: yesAdvanced Functional Materials, EarlyView.
We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

Magneto-resistance in pristine and irradiated TaAs2

open access: yesAIP Advances, 2019
Here we report the single crystal synthesis, characterization and the systematic study of the magneto-transport and magnetization measurements up to a magnetic field of 14 T and down to 3 K from room temperature in the semimetal TaAs2.

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

open access: yesAdvanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.
