Nobody doubts that the discovery of hadrons with charm hidden and open variety – i.e. charmonium as well D mesons was instrumental in acceptance Standard Model (SM) general, quarks physical degrees freedom, rather than objects mere mathematical convenience, particular. Yet is all too often viewed a quantum number great past no particularly interesting future. This due to SM predictions dull electroweak phenomenology CKM parameters, low frequency for [Formula: see text] oscillations, tiny (at...
We report large nonreciprocity in the transmission of shear-horizontal surface acoustic waves (SHSAWs) on ${\mathrm{Li}\mathrm{Ta}\mathrm{O}}_{3}$ substrate coated with a $\mathrm{Fe}\text{\ensuremath{-}}\mathrm{Co}\text{\ensuremath{-}}\mathrm{Si}\text{\ensuremath{-}}\mathrm{B}/\mathrm{Ni}\text{\ensuremath{-}}\mathrm{Fe}\text{\ensuremath{-}}\mathrm{Cu}$ magnetoelastic bilayer. The difference saturation magnetization two layers not only brings nonreciprocal spin (SWs), but also ensures...
We report unambiguous observation of spatial self-phase modulation (SSPM) in a dispersive suspension graphite flakes. This coherent nonlinear optical effect bulk is found to be broadband and large, with third-order susceptibility χ(3) 2.2 × 10−9 esu (i.e., 3.1 10−17 m2/V2 SI units) at 532 nm excitation. Comparison other carbon allotropes shows that this value 5 107 times higher than C60 but ∼50 lower graphene, fully exhibiting the electronic origin SSPM.
The similarities to cuprates make iridates an interesting potential platform for investigating superconductivity. Equally attractive are their puzzling complex intrinsic interactions. Here, we report ultrafast optical spectroscopy investigation of a coherent phonon mode in Sr3Ir2O7, bilayer Ruddlesden-Popper perovskite iridate. An anomaly the A1g (ν = 4.4 THz) is unambiguously observed below Néel temperature (TN), which attribute pseudospin-lattice coupling (PLC). Significantly, find that...
Lack of nonreciprocity is one the major drawbacks solid-state acoustic devices, which has hindered development microwave-frequency isolators and circulators. Here, we report a giant nonreciprocal transmission shear-horizontal surface waves (SH-SAWs) on LiTaO3 substrate coated with negative–positive magnetostrictive bilayer structure Ni/Ti/FeCoSiB. Although static magnetic moments two layers are parallel, SH-SAWs can excite optical-mode spin much stronger than acoustic-mode ones at relatively...
We report an ultrafast lattice dynamics investigation of the topological Dirac semimetal $\mathrm{C}{\mathrm{d}}_{3}\mathrm{A}{\mathrm{s}}_{2}$. A coherent phonon beating among three evenly spaced ${A}_{1g}$ optical modes (of frequencies 1.80, 1.96, and 2.11 THz, respectively) is unambiguously observed. The two side originate from counter helixes composing Cd vacancies. Significantly, such helix vacancy-induced (HVP) experience prominent extra waning in their as temperature increases, which...
We conceive and construct an on-site in situ high-pressure time-resolved ultrafast optical spectroscopy instrument that facilitates pump–probe dynamics measurements under high pressure conditions. integrate system with a diamond anvil cell (DAC) system. Significantly, both the DAC sample are fixed within light path without motion rotation throughout whole experiment, including tuning calibrating pressure. This thus avoids introducing artifacts due to or rotation, enabling precision...
Abstract Currently, the surface acoustic wave (SAW) magnetic field sensing technique utilises SAW velocity/frequency mechanism of magnetoacoustic interaction as an indicator sensitivity mechanism. However, this method has low and poor stability. To address problem, a dynamic magnetoelastic coupling theoretical model is constructed to theoretically simulate influence Δ E effect magnetically sensitive thin films on propagation attenuation. This study describes high-sensitivity based The...
In this study, we report giant nonreciprocal transmission of shear-horizontal surface acoustic waves (SH-SAWs) in a ferromagnetic bilayer structure with negative–positive magnetostriction configuration. Although the directions magnetization neighboring layers are parallel, SH-SAWs can excite optical-mode spin (SWs) via magnetoelastic coupling at relatively low frequencies, which is much stronger than acoustic-mode SWs high frequencies. The measured magnitude nonreciprocity or isolation...
