The quantum indeterminacy caused by non-commutativity of observables at different times sets a lower bound on the voltage noise power spectrum in any conducting material. This is calculated explicitly case semiconductors with conical energy-momentum dispersion charge carriers. It possesses all characteristic properties 1/f noise. Its momentum decomposition found to be singular zero particle mom...

Direct measurement of local phonon dispersion in individual nanostructures can greatly advance our understanding their electrical, thermal, and mechanical properties. However, such experimental measurements require extremely high detection sensitivity combined spatial, energy momentum resolutions, thus has been elusive. Here, we develop a four-dimensional electron loss spectroscopy (4D-EELS) te...

Shliomis [“Comment on ‘Consistent hydrodynamcs of ferrofluids’ [Phys. Fluids 34, 013319 (2022)],” Phys. 079101 (2022)] employed an inappropriate definition for the total angular momentum ferrofluids to formulate conservation law momentum. We show that widely accepted dispersion spinning particles leads a different expression Furthermore, Brenner's [Annu. Rev. Fluid Mech. 2, 137 (1970)] relation...

Abstract A design of a compact hadron driver for future cancer therapies based on the induction synchrotron concept is given. In order to realize slow extraction technique in fast cycling synchrotron, which allows energy sweep beam scanning, zero momentum-dispersion D ( s ) region and high flat are necessary. The present meets both requirements. lattice has two-fold symmetry with circumference ...

Using the QCD operator product expansion, we derive the real part of the transverse and longitudinal vector-vector correlation function with the quantum numbers of the ρ and ω mesons to leading order in density and three momentum (q2) for ω2 → −∞. The operator product expansion provides, through the Borel transformed energy dispersion relation, a model independent constraint for the momentum de...

When neutrinos travel through a normal matter medium, the electron neutrinos couple differently to gravity compared to the other neutrinos, due to the presence of electrons in the medium and the absence of the other charged leptons. We calculate the momentum-dependent part of the matter-induced gravitational couplings of the neutrinos under such conditions, which arise at order g/M W , and dete...

We extend our previous results [R. Baer et al., J. Chem. Phys. 126, 014705 (2007).] to develop a simple theory of localized surface plasmon-polariton (LSPP) dispersion on regular arrays of metal nanoparticles in the weak-field and weak-damping limits. This theory describes the energy-momentum as well as the polarization-momentum properties of LSPP waves, both of which are crucial to plasmonic d...

Studying interacting fermions in one dimension at high energy, we find a hierarchy in the spectral weights of the excitations theoretically, and we observe evidence for second-level excitations experimentally. Diagonalizing a model of fermions (without spin), we show that levels of the hierarchy are separated by powers of R^{2}/L^{2}, where R is a length scale related to interactions and L is t...

The electronic stopping power of liquid water for protons over the 50 keV to 10 MeV energy range is studied using an improved dielectric response model which is in good agreement with the best available experimental data. The mean excitation energy (I) of stopping power theory is calculated to be 77.8 eV. Shell corrections are accounted for in a self-consistent manner through analytic dispersio...

Steady-state RANS Computational Fluid Dynamics simulations of pollutant dispersion in the neutrally stable atmospheric boundary layer are made with the commercial code Fluent 6.1 for three case studies: plume dispersion from an isolated stack, low-momentum exhaust from a rooftop vent on an isolated cubic building model and high-momentum exhaust from a rooftop stack on a low-rise rectangular bui...
