Electrobaryonic axion: hair of neutron stars

open access: yesJournal of High Energy Physics
Axion-like particles are predicted in many physics scenarios beyond the Standard Model (SM). Their interactions with SM particles may arise from the triangle anomaly of the associated global symmetry, along with other SM global and gauge symmetries ...

Decoupling Degradation at the Electrode Interfaces in Prussian White Full Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Prussian White (PW) as a sodium‐ion battery (SIB) cathode material is advancing, having already been commercialized. Yet, capacity fade and cyanide‐related safety risks persist. By integrating Mössbauer‐ and online electrochemical mass spectrometry, this study analyzes degradation in PW cells, observing hydrogen and cyanide evolution.

Detection of Simultaneous Quasiperiodic Oscillation Triplets in 4U 1728-34 and Constraining the Neutron Star Mass and Moment of Inertia

open access: yesThe Astrophysical Journal
We report simultaneous detection of twin kHz and ∼40 Hz quasiperiodic oscillations (QPOs) in the time-resolved analysis of the AstroSat/LAXPC observation of the neutron star low-mass X-ray binary, 4U 1728-34.

Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.

On the Dynamical Evolution of the Asteroid Belt in a Massive Star–Neutron Star Binary

open access: yesThe Astrophysical Journal
Some fast radio bursts (FRBs) exhibit repetitive behaviors, and their origins remain enigmatic. It has been argued that repeating FRBs could be produced by the interaction between a neutron star and an asteroid belt.

Accretion in supergiant High Mass X-ray Binaries

open access: yesEPJ Web of Conferences, 2014
Supergiant High Mass X-ray Binary systems (sgHMXBs) consist of a massive, late type, star and a neutron star. The massive stars exhibits strong, radiatively driven, stellar winds.
