Optical Self‐Tuning of Ferroelectric Metasurfaces Infiltrated with Nematic Liquid Crystals via Photovoltaic Effect

Advanced Optical Materials, EarlyView.
A novel scheme is introduced to achieve optical self‐tuning in ferroelectric lithium niobate (LN) metasurfaces equipped with a thin film of liquid crystals (LCs). The resonant optical field distributions inside the meta‐atoms can induce a photovoltaic (PV) field, which reorients the surrounding LCs.

Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

Advanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the

Neutrino masses and magnetic moments of electron and muon in the Zee Model

Journal of High Energy Physics, 2022
We explore parameter space in the Zee Model to resolve the long-standing tension of the electron and muon anomalous magnetic moment (AMM). The model comprises a second Higgs doublet and a charged singlet at electroweak scale and generates Majorana ...

Limits on the Dipole Moments of the $\tau$-Lepton via the Process $e^{+}e^{-}\to \tau^+ \tau^- \gamma in a Left-Right Symmetric Model

, 2004
Limits on the anomalous magnetic moment and the electric dipole moment of the $\tau$ lepton are calculated through the reaction $e^{+}e^{-}\to \tau^+ \tau^- \gamma$ at the $Z_1$-pole and in the framework of a left-right symmetric model.

Spontaneous R-Parity violation bounds [PDF]

, 2001
We investigate bounds from tree-level and one-loop processes in generic supersymmetric models with spontaneous R-parity breaking in the superpotential. We analyse the bounds from a general point of view. The bounds are applicable both for all models with

All‐Dielectric Metasurface‐Based Gap Waveguides

Advanced Photonics Research, EarlyView.
Dielectric metasurface‐based waveguides (metawavegides) offer several advantages over conventional waveguides, making them ideal for integrated photonics. A design of a metawaveguide composed of a pair of dielectric metasurfaces is proposed, where each metasurface behaves as a wall of either a perfect electric conductor or a perfect magnetic conductor,

Palаeomagnetism of the Vendian traps of Volyn, southwestern margin of the East European platform. P. 1: palаeomagnetic directions and poles

Геофизический журнал, 2022
In Earth’s geological evolution the Vendian is significant because: 1) it preceded the «Cambrian Evolutionary explosion» when the multicellular organisms became suddenly much more diverse; 2) it is associated with the global tectonic and ...

Anomalous magnetic moment of the muon in the two Higgs doublet model [PDF]

, 2002
We calculate the new physics effects on the anomalous magnetic moment of the muon in the framework of the two Higgs doublet model. We predict an upper bound for the lepton flavor violating coupling, which is responsible for the point like interaction ...

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control

Advanced Science, EarlyView.
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Constraining exotic spin dependent interactions of muons and electrons

European Physical Journal C: Particles and Fields, 2019
Many experiments have been performed to search for the exotic spin-dependent interactions in ranges from $$\sim \upmu $$ ∼μ m to astrophysical range which corresponds to the energy scale of less than $$\sim $$ ∼ 10 eV.
