Effect of signal to noise ratio on luminescence property of YPO4:Eu
Materials Letters: X, 2022 An effect of variation of slit widths of excitation and emission monochromators on emission intensity, peak position and asymmetric ratio of Eu3+ has been observed in YPO4:Eu3+. Stark splitting is observed.

Lattice-plasmon-induced asymmetric transmission in two-dimensional chiral arrays
APL Photonics, 2022 Asymmetric transmission—direction-selective electromagnetic transmission between two ports—is a phenomenon exhibited by two-dimensional chiral systems. The possibility of exploiting this phenomenon in chiral metasurfaces opens exciting possibilities for ...

On stabilizability of the upper equilibrium of the asymmetrically excited inverted pendulum
Electronic Journal of Qualitative Theory of Differential Equations, 2018 Using purely elementary methods, necessary and sufficient conditions are given for the existence of $T$-periodic and $2T$-periodic solutions around the upper equilibrium of the mathematical pendulum when the suspension point is vibrating vertically with ...

Dynamic formation of Rydberg aggregates at off-resonant excitation [PDF]
, 2013 The dynamics of a cloud of ultra-cold two-level atoms is studied at off-resonant laser driving to a Rydberg state. We find that resonant excitation channels lead to strongly peaked spatial correlations associated with the buildup of asymmetric excitation

Isospin dependence of mass-distribution shape of fission fragments of Hg isotopes [PDF]
, 2013 Using an improved scission-point model, the mass distributions are calculated for induced fission of even Hg isotopes with mass numbers A=174 to 196. With increasing A of a fissioning AHg nucleus the mass distribution evolves from symmetric for 174Hg, to
