Intertwined Topological Phases in TaAs2 Nanowires with Giant Magnetoresistance and Quantum Coherent Surface Transport

Advanced Materials, EarlyView.
Synthesis of topological semimetal TaAs2 nanowires in situ encapsulated with a thin SiO2 shell unravel a richness of intertwined topological phases manifested by their magnetotransport features: A near‐room‐temperature metal‐to‐insulator transition, strong expressions of topologically nontrivial surface transport, giant magnetoresistance with direction‐

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Supersymmetry Breaking by Hidden Matter Condensation in Superstrings [PDF]

Phys.Lett. B343 (1995) 161-167, 1994
We show that supersymmetry can be broken mainly by hidden matter condensates in the observable matter direction in generic superstring models. This happens only when the fields whose VEVs give masses to hidden matter do not decouple at the condensation scale.

Revealing the Origin and Nature of the Buried Metal‐Substrate Interface Layer in Ta/Sapphire Superconducting Films

Advanced Science, EarlyView.
The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Electrical Control of Magnetic Order Transition in 2D Antiferromagnetic Semiconductor FePS3

Advanced Science, EarlyView.
The magnetic order transition of FePS3 from antiferromagnetic (AFM) to ferrimagnetic (FIM) and back to AFM is achieved via electron doping induced by various organic cations intercalation. The carrier doping‐dependent magnetic transition offers an effective approach to engineering magnetism in 2D magnetic materials by purely electrical means for future

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...

Matter-wave solitons supported by dissipation [PDF]

, 2005
We show how novel types of long-lived self-localized matter waves can be constructed with Bose-Einstein condensates. The ingredients leading to such structures are a spatial phase generating a flux of atoms towards the condensate center and the dissipative mechanism provided by the inelastic three-body collisions in atomic Bose-Einstein condensates ...

Signatures of the Correlated‐Hopping Interaction in Non‐Linear Transport Through a Quantum Dot

Annalen der Physik, EarlyView.
Non‐linear thermoelectric transport through a quantum dot is studied, in order to elucidate the signatures of so‐called correlated hopping. The line shapes of the differential conductance and the Seebeck coefficient as functions of gate voltage are clear indicators of this important interaction term.

Electrical Manipulation of Intervalley Trions in Twisted MoSe2 Homobilayers at Room Temperature

Advanced Physics Research, EarlyView.
This study explores electrical control of excitonic complexes in twisted MoSe2 homobilayer devices at room temperature. Gate‐dependent photoluminescence reveals distinct exciton‐trion conversion response, analyzed for angles of ∼1°, ∼4°, and ∼18°. Density functional theory calculations suggest the formation of intervalley hybrid trions that exhibit a ...

Atom interferometry with Bose-Einstein condensates in a double-well potential [PDF]

Phys. Rev. Lett. 92, 050405 (2004), 2003
A trapped-atom interferometer was demonstrated using gaseous Bose-Einstein condensates coherently split by deforming an optical single-well potential into a double-well potential. The relative phase between the two condensates was determined from the spatial phase of the matter wave interference pattern formed upon releasing the condensates from the ...
