We show that gravitons with energy $E<\mathrm{\ensuremath{\Omega}}$, where $\mathrm{\ensuremath{\Omega}}$ is the gap a localized nonrelativistic system, can be detected by finite-time interactions detector. Our detector based on quadrupole moment interaction between hydrogen atom and gravitational field in linearized approximation. In this model, external agent responsible for switching an o...

A beam with an angular-dependant phase Φ = ℓϕ about the beam axis carries an orbital angular momentum of ℓℏ per photon. Such beams are exploited to provide superresolution in microscopy. Creating extreme ultraviolet or soft-x-ray beams with controllable orbital angular momentum is a critical step towards extending superresolution to much higher spatial resolution. We show that orbital angular m...

The evolution of orbital angular momentum distributions within the radiative parton model is studied. We use different scenarios for the helicity weighted parton distributions and consider a broad range of input distributions for orbital angular momentum. In all cases we are lead to the conclusion that the absolute value of the average orbital angular momentum per parton peaks at relatively lar...

In this paper, I discuss observations indicating that homogenization, in its standard version based on weak compactness, generally does not work for dynamic materials with arbitrary material geometry. A remarkable exception is represented by the spatial-temporal laminates where such compactness can be established. For the slow (timelike) laminates, this was done in [18] with the use of energy b...

Angular momentum is a conserved physical quantity for isolated systems where no external moments act about a body's center of mass (CM). However, in the case of legged locomotion, where the body interacts with the environment (ground reaction forces), there is no a priori reason for this relationship to hold. A key hypothesis in this paper is that angular momentum is highly regulated throughout...

It has been recently shown [M. Robnik and L. Salasnich, J. Phys. A: Math. Gen., 30, 1719 (1997)] that the WKB series for the quantization of angular momentum L converges to the exact value L = h̄l(l + 1), if summed over all orders, and gives the Langer formula L = h̄(l + 1/2) at the leading order. In this work we solve the eigenvalue problem of the angular momentum operator by using the supersymm...
