Halide perovskite nanocrystals are suitable materials for photonic devices because their highly efficient luminescence can be tuned over a wide wavelength range by changing the nanocrystal composition and size. Here, we report on high-order harmonic generation in solution-processed ${\mathrm{CsPbBr}}_{3}$ film that is excited strong midinfrared laser. We observe harmonics up to 13th order, whic...

Tagged Magnetic Resonance Imaging (MRI) is a noninvasive technique for examining myocardial function and deformation. Tagged MRI can also be used in quasi-static MR elastography to acquire strain maps of other biological soft tissues. Harmonic phase (HARP) provides automatic and rapid analysis of tagged MR images for the quantification and visualization of myocardial strain. We propose a new ar...

The harmonic oscillator is one of the most widely used model systems in physics: an indispensable theoretical tool in a variety of fields. It is well known that an otherwise linear oscillator can attain novel and nonlinear features through interaction with another dynamical system. We investigate such an interacting system: a superconducting LC-circuit dispersively coupled to a superconducting ...

Multilevel inverter as compared to single level inverters have advantages like minimum harmonic distortion, reduced Electro Magnetic Interference (EMI/RFI) generation and can operate on several voltage levels. In this paper a new topology of cascaded multilevel inverter using reduced number of switches, resulting in higher output voltage levels is proposed. There are five series connected H-bri...

Thin-film materials from μm thickness down to single-atomic-layered 2D play a central role in many novel electronic and optical applications. Coherent, nonlinear (NLO) μ-spectroscopy offers insight into the local thickness, stacking order, symmetry, or vibrational properties. Thin films are usually supported on multi-layered substrates leading (multi-)reflections, interference, phase jumps at i...

The harmonic index H(G) , of a graph G is defined as the sum of weights 2/(deg(u)+deg(v)) of all edges in E(G), where deg (u) denotes the degree of a vertex u in V(G). In this paper we define the harmonic polynomial of G. We present explicit formula for the values of harmonic polynomial for several families of specific graphs and we find the lower and upper bound for harmonic index in Caterpill...

An asymmetric plasmonic nanoantenna mediates the nonlinear mixing between ultrashort infrared laser pulses at frequency ω and 2ω. The third harmonic + sum 2ω are coherent degenerate visible 3ω. Consequently, a relative time delay pumps brings strong modulation of power 3ω due to interference. This phase-dependent modulation, as presented in article number 2200757 by Michele Celebrano co-workers...

Interference is the cornerstone of Huygens source design for reshaping and controlling scattering patterns. The conventional underpinning principle, such as Kerker effect, interference electric magnetic dipole quadrupole modes. Here a route to realize transverse through employing only between demonstrated. proposed approach numerically validated in an ultra-thin Silicon square nanoplate metasur...

The inner-outer part factorisation of analytic representations in the unit disk is used for an effective characterisation of the number-phase statistical properties of a quantum harmonic oscillator. It is shown that the factorisation is intimately connected to the number-phase Weyl semigroup and its properties. In the Barut-Girardello analytic representation the factorisation is implemented as ...

The interference pattern of the resonance fluorescence from a J = 1/2 to J = 1/2 transition of two identical atoms confined in a three-dimensional harmonic potential is calculated. Thermal motion of the atoms is included. Agreement is obtained with experiments [Eichmann et al., Phys. Rev. Lett. 70, 2359 (1993)]. Contrary to some theoretical predictions, but in agreement with the present calcula...
