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.

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 ...

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.

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.

Simulation of granular flow in a rotating frame of reference using the discrete element method
, 2020 Over the years, the Discrete Element Method (DEM) has attracted significant attention for its capacity to simulate granular flows because it captures physical phenomena that cannot be observed using continuum methods.

Radar Method in a Uniformly Accelerated Reference Frame
Siberian Journal of Physics, 2023 The purpose of this work is to generalize the radar method known for the inertial frame of reference to the case of a uniformly accelerated frame of reference.The derivation of the corresponding formulas is based on the standard for the theory of ...

Teleparallel Theories of Gravity: Illuminating a Fully Invariant Approach [PDF]
, 2019 Teleparallel gravity and its popular generalization $f(T)$ gravity can be formulated as fully invariant (under both coordinate transformations and local Lorentz transformations) theories of gravity.

Radiation from Violently Accelerated Bodies [PDF]
, 2001 A determination is made of the radiation emitted by a linearly uniformly accelerated uncharged dipole transmitter. It is found that, first of all, the radiation rate is given by the familiar Larmor formula, but it is augmented by an amount which becomes ...
