Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

$M$-ideals and quasi-triangular algebras

Illinois Journal of Mathematics, 1987
If \({\mathcal P}\) is a linearly ordered set of projections on a Hilbert space and \({\mathcal K}\) is the ideal of compact operators, then \(\text{Alg}\, {\mathcal P}+{\mathcal K}\) is the quasi-triangular algebra associated with \({\mathcal P}.\) We show that \((\text{Alg}\,{\mathcal P}+{\mathcal K})/\text{Alg}\,{\mathcal P}\) is an M-ideal in ...

Quasi-freestanding epitaxial silicene on Ag(111) by oxygen intercalation [PDF]

, 2016
Silicene is a monolayer allotrope of silicon atoms arranged in a honeycomb structure with massless Dirac fermion characteristics similar to graphene. It merits development of silicon-based multifunctional nanoelectronic and spintronic devices operated at

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

The Demand for Organic, Integrated-Agriculture, and Conventional Fresh Vegetables: A Censored Inverse Almost Ideal Demand System [PDF]

The Inverse Almost Ideal Demand System is employed for the empirical analysis of the demand for organic, integrated-agriculture, and conventional fresh vegetables, using a cross section data surveyed in Rethymno, Greece during the 2005-06 period.

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Ideal-Based Quasi Cozero Divisor Graph of a Commutative Ring

Journal of Mathematics
Let R be a commutative ring with identity and I be an ideal of R. The zero-divisor graph of R with respect to I, denoted by ΓIR, is the graph whose vertices are the set x∈R∖I xy∈I for some y∈R∖I with distinct vertices x and y are adjacent if and only if ...

Density fluctuations in a very elongated Bose gas : from ideal gaz to quasi-condensate [PDF]

, 2009
International audienceWe report in situ measurements of density fluctuations in a quasi one dimensional Rubidium Bose gas at thermal equilibrium in an elongated harmonic trap. We observe an excess of fluctuations compared to the shot noise level expected

Quasi-ideal feedback-loop supercurrent diode [PDF]

We suggest using a device called the Bootstrap Superconducting Quantum Interference Device (BS-SQUID) to break the reciprocity in charge transport. This device uses magnetic flux back-action to create a nonreciprocal current-voltage characteristic, which
