Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Análisis cuantitativo de la investigación en invasiones biológicas en Chile: tendencias y desafíos Quantitative analysis of the research in biological invasions in Chile: Trends and challenges

open access: yesRevista Chilena de Historia Natural, 2009
En las últimas dos décadas, el estudio de las invasiones biológicas ha alcanzado un auge sin precedentes a nivel mundial tanto en sus dimensiones teóricas como aplicadas. En Chile, las invasiones biológicas parecieran ser un tema relativamente nuevo.

Exotic nuclei [PDF]

open access: yesВестник Российской академии наук, 2019
One of the most interesting and intensively examined research directions in nuclear physics, i.e., the production and investigation of exotic nuclei in the vicinity of drip-lines is investigated. An historical overview of the development of research area is provided.

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

open access: yesAdvanced Materials, EarlyView.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

About the Absence of Exotics and the Coulomb Branch Formula [PDF]

open access: yes, 2014
The absence of exotics is a conjectural property of the spectrum of BPS states of four--dimensional $\mathcal{N}=2$ supersymmetric QFT's. In this letter we revisit the precise statement of this conjecture, and develop a general strategy that, if ...

Axial Vector $Z'$ and Anomaly Cancellation

open access: yes, 2017
Whilst the prospect of new $Z'$ gauge bosons with only axial couplings to the Standard Model (SM) fermions is widely discussed, examples of anomaly-free renormalisable models are lacking in the literature.

Phase Engineering of Nanomaterials (PEN): Evolution, Current Challenges, and Future Opportunities

open access: yesAdvanced Materials, EarlyView.
This review summarizes the synthesis, phase transition, advanced characterization spanning ex situ to in situ and operando techniques, and diverse applications of phase engineering of nanomaterials (PEN). It further outlines key challenges and future opportunities, such as phase stability, architecture control, and artificial intelligence (AI)‐driven ...

The dynamical diquark model: first numerical results

open access: yesJournal of High Energy Physics, 2019
We produce the first numerical predictions of the dynamical diquark model of multiquark exotic hadrons. Using Born-Oppenheimer potentials calculated numerically on the lattice, we solve coupled and uncoupled systems of Schrödinger equations to obtain ...

Search for excited τ-leptons and leptoquarks in the final state with τ-leptons and jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search is reported for excited τ-leptons and leptoquarks in events with two hadronically decaying τ-leptons and two or more jets. The search uses proton-proton (pp) collision data at s $$ \sqrt{s} $$ = 13 TeV recorded by the ATLAS experiment during the
