Excitonic instability in optically-pumped three-dimensional Dirac materials

open access: yes, 2017
Recently it was suggested that transient excitonic instability can be realized in optically-pumped two-dimensional (2D) Dirac materials (DMs), such as graphene and topological insulator surface states.

Distant Storms Can Affect Seismic Noise Crustal Monitoring

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Using seismic noise interferometry to monitor the Earth's interior relies on continuous seismic wavefields produced by stable, invariant sources. In numerous applications, this condition is relaxed, arguing that secondary scattering effects render the late coda source independent.

Simultaneous Broadband Nonreciprocal Thermal Emission for Transverse Magnetic and Electric Polarizations

open access: yesNanophotonics, Volume 15, Issue 6, 27 March 2026.
ABSTRACT Objects violating Kirchhoff's law of thermal radiation exhibit unequal absorptivity or emissivity at symmetrical polar angles relative to the normal direction, providing prerequisites for approaching thermodynamic limits in radiative cooling and photon energy conversion, such as the Landsberg limit.

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

HVS7: a chemically peculiar hyper-velocity star

open access: yes, 2008
Context: Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelerates one component of the binary to beyond the Galactic escape velocity ...

The Osteoinductive Effect of Water-Soluble Matrix from Nano-Nacre Particles of Haliotis diversicolor (H. diversicolor) Abalone on MC3T3-E1 Osteoblasts

open access: yesApplied Sciences
Osteoporosis is characterized by an imbalance between osteoblastic bone formation and osteoclastic bone resorption, leading to an increased risk of fractures.

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Whole person healthcare as social and environmental justice: new research directions toward a paradigmatic integration of an ecological whole system medicine framework

open access: yesFrontiers in Communication
With increasing recognition of the interdependencies of human and planetary health, calls for a socially and environmentally just framework of health have centered on whole person healthcare (WPHC) approaches.
