Inertial effects on neutrino oscillations and decoherence: A wave packet approach
Physics Letters B, 2021 We study the impact of inertial effects on neutrino oscillations and decoherence. Toward this end, we describe the propagation of neutrino wave packets by employing the density matrix formalism.

Informational Reinterpretation of the Mechanics Notions and Laws
Entropy, 2020 The informational re-interpretation of the basic laws of the mechanics exploiting the Landauer principle is suggested. When a physical body is in rest or it moves rectilinearly with the constant speed, zero information is transferred; thus, the ...

The Definition and Stability of Local Inertial Reference Frames [PDF]
Symposium - International Astronomical Union, 1990 Inertial reference frames spanning approximately 10°-30° square on the sky and capable of locating objects to few-hundred microarcsecond accuracies are useful for a broad class of astrometric measurements. Deep space tracking and general relativistic angular deflection experiments are examples of astrometric measurements which can profitably reference ...

Mesoscopic Mechanical Resonators as Quantum Non-Inertial Reference Frames [PDF]
, 2015 An atom attached to a micrometer-scale wire that is vibrating at a frequency of 100 MHz and with displacement amplitude 1 nm experiences an acceleration magnitude 10^9 ms^-2, approaching the surface gravity of a neutron star.

Jerk and Hyperjerk in a Rotating Frame of Reference [PDF]
, 2015 Jerk is the derivative of acceleration with respect to time and then it is the third order derivative of the position vector. Hyperjerks are the n-th order derivatives with n>3.

Work has nothing to do with energy expenditure [PDF]
Revista Brasileira de Ensino de Física, 2020 We show that, contrary to common sense, the author of mechanical work does not necessarily provide the required energy. By the most simple example one can ever conceive – a standing person starting to move, this point is made clear: the floor does not ...

Hull Deformation Measurement With Large Angles Based on Inertial Sensors
IEEE Access, 2020 The partial reference is used in large ships to measure the hull deformation, which is normally realized through the transfer alignment between the master inertial navigation system and the slave inertial navigation system.

On the trajectories of bodies in non-inertial reference frames
Vestnik Tomskogo gosudarstvennogo universiteta. Matematika i mekhanika, 2023 This paper considers a trajectory of the body moving under the influence of the force F in a non-inertial reference frame (NRF), which is "tied" to a given curve y = y(x) and is described by a natural movable basis τ-n. For this NRF, a system of linear differential equations is obtained to simulate various types of trajectories resulting from the ...

Unitary representations of the Galilean line group: Quantum mechanical principle of equivalence
, 2011 We present a formalism of Galilean quantum mechanics in non-inertial reference frames and discuss its implications for the equivalence principle. This extension of quantum mechanics rests on the Galilean line group, the semidirect product of the real ...
