We analyze the possibility of odd-frequency pairing near a quantum critical point(QCP) in metal. consider model with dynamical interaction $V({\mathrm{\ensuremath{\Omega}}}_{n})\ensuremath{\sim}1/{|{\mathrm{\ensuremath{\Omega}}}_{n}|}^{\ensuremath{\gamma}}$ (the $\ensuremath{\gamma}$ model). This gives rise to non-Fermi liquid normal state and is attractive for pairing. The two trends compete e...
We investigate a particle confined within a double-well potential, its behavior described by a one-dimensional nonlinear Schrödinger equation. Transitions between the two lowest self-trapped states of this system are studied, in the two-mode approximation, under the influence of the external time-dependent perturbation. If the perturbation is harmonic in time, with the frequency omega, then tra...
in this article we introduce the notion of textit{fractal $omega$-operad} emerging from a natural $omega$-operad associated to any coglobular object in the category of higher operads in batanin's sense, which in fact is a coendomorphism $omega$-operads. we have in mind coglobular object of higher operads which algebras are kind of higher transformations. it follows that this natural $omega$-op...
Computational fluid dynamics (CFD) is used widely in design of rotary blood pumps. The choice of turbulence model is not obvious and plays an important role on the accuracy of CFD predictions. TASCflow (ANSYS Inc., Canonsburg, PA, U.S.A.) has been used to perform CFD simulations of blood flow in a centrifugal left ventricular assist device; a k-epsilon model with near-wall functions was used in...
We introduce an exact framework to compute the positive frequency moments $M^{(\alpha)}(\mathbf{q})=\braket{\omega^\alpha}$ of different dynamic properties from imaginary-time quantum Monte Carlo data. As a practical example, we obtain first five structure factor $S(\mathbf{q},\omega)$ uniform electron gas at electronic Fermi temperature based on \emph{ab initio} path integral simulations. find...
The role of a finite exposure time sigma on measuring rheological properties using microrheology techniques is theoretically investigated. We concentrate on studying fluid models displaying a plateau in the mean-squared displacement (MSD) of the embedded probe particle. A model is developed to compare the resulting experimentally measured MSD of the particle to its expected value in the fluid m...
within the context of climate change, water scarcity is the major constraint to the viability of many crops. thus, it is necessary to develop strategies for sustainable water management, and introduce alternative crops to sustain the viability of agro-ecosystems. the main objective of this work was to assess the performance of hemp (cannabis sativa l.) subjected to different plant densities and...
The dissociative ionization of $H_2^+$ in linearly polarized, 400 nm laser pulses is simulated by solving a three-particle time-dependent Schr\"odinger equation full dimensionality. joint energy spectra (JES) are computed for $\cos^8$ and flat-top envelopes using the surface flux (tSurff) methods. In JES, sharing $n$ photon energies $\omega$ nuclear kinetic release (KER) $E_N$ electronic KER $E...
[1] Visible-near infrared reflectance spectra acquired by the Mars Express Observatoire pour la Minéralogie, l’Eau, les Glaces et l’Activité (OMEGA) spectrometer are used to estimate the absolute water content within the uppermost fraction of the Martian regolith. This upper surface layer represents the boundary between the regolith and atmosphere; thus the amount of water stored in these two r...
We study an array of strongly correlated quantum dots complex SYK type and account for the effects quadratic terms added to Hamiltonian; both local inter-dot tunneling are considered in non-Fermi-liquid temperature range $T \gg T_{FL}$. take into soft-mode fluctuations demonstrate their relevance physical observables. Electric $\sigma(\omega,p)$ thermal $\kappa(\omega,p)$ conductivities calcula...
