Phonons in Single‐Domain κ‐Ga2O3 Studied by Polarization Angle‐Resolved Raman Scattering

open access: yesAdvanced Electronic Materials, EarlyView.
Single‐domain κ‐Ga2O3 is systematically studied using advanced Raman spectroscopy, revealing over 100 Raman‐active phonon modes. These modes are compared with theoretical predictions and organized within a newly established nomenclature, offering a robust reference for future research.

Orbital motions as gradiometers for post-Newtonian tidal effects [PDF]

open access: yes, 2014
The direct long-term changes occurring in the orbital dynamics of a local gravitationally bound binary system $S$ due to the post-Newtonian tidal acceleration caused by an external massive source are investigated.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

open access: yesAdvanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Gravitational wave detector response in terms of spacetime Riemann curvature

open access: yes, 2013
Gravitational wave detectors are typically described as responding to gravitational wave metric perturbations, which are gauge-dependent and --- correspondingly --- unphysical quantities.

The Direct Effect of Toroidal Magnetic Fields on Stellar Oscillations: An Analytical Expression for the General Matrix Element [PDF]

open access: yes, 2017
Where is the solar dynamo located and what is its modus operandi? These are still open questions in solar physics. Helio- and asteroseismology can help answer them by enabling us to study solar and stellar internal structures through global oscillations.

Anomalous Magnetization Dynamics After Dual Optical Excitation

open access: yesAdvanced Physics Research, EarlyView.
We demonstrate that dual‐pump femtosecond excitation in copper leads to a pronounced, non‐additive change in spin and orbital relaxation dynamics compared to single‐pulse excitation. Time‐resolved magneto‐optical Kerr effect measurements reveal a 2.5× increase in angular momentum decay time, highlighting a new route to ultrafast control of electronic ...

Constraining smoothness parameter and the DD relation of Dyer-Roeder equation with supernovae

open access: yes, 2013
Our real universe is locally inhomogeneous. Dyer and Roeder introduced the smoothness parameter $\alpha$ to describe the influence of local inhomogeneity on angular diameter distance, and they obtained the angular diameter distance-redshift approximate ...

Universal Entanglement and an Information‐Complete Quantum Theory

open access: yesAdvanced Physics Research, EarlyView.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

open access: yesJournal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...
