Phase transitions in paradigm shift models. [PDF]

PLoS ONE, 2013
Two general models for paradigm shifts, deterministic propagation model (DM) and stochastic propagation model (SM), are proposed to describe paradigm shifts and the adoption of new technological levels.

Synchronous Phase Shift at LHC

, 2013
The electron cloud in vacuum pipes of accelerators of positively charged particle beams causes a beam energy loss which could be estimated from the synchronous phase.

Black holes, heavy states, phase shift and anomalous dimensions [PDF]

SciPost Physics, 2018
We compute the phase shift of a highly energetic particle traveling in the background of an asymptotically AdS black hole. In the dual CFT, the phase shift is related to a four point function in the Regge limit.

High SNR BER Comparison of Coherent and Differentially Coherent Modulation Schemes in Lognormal Fading Channels

, 2014
Using an auxiliary random variable technique, we prove that binary differential phase-shift keying and binary phase-shift keying have the same asymptotic bit-error rate performance in lognormal fading channels.

Two-photon-absorption-based OSNR monitor for NRZ-PSK transmission systems [PDF]

, 2010
A two-photon absorption microcavity-based technique for monitoring in-band optical signal-to-noise ratio (OSNR) in nonreturn-to-zero phase-shift-keying systems is presented.

Momentum Dependence of Phase Shifts [PDF]

Physical Review, 1955
A lower limit is found for the momentum derivative of the scattering phase shifts of a relativistic neutral two-particle system when the interaction is of finite range.

Performance of Equal Phase-Shift Search for One Iteration

, 2007
Grover presented the phase-shift search by replacing the selective inversions by selective phase shifts of $\pi /3$. In this paper, we investigate the phase-shift search with general equal phase shifts.

The Role of Inert Objects in Quantum Mechanical Phase [PDF]

, 1999
Quantum mechanical foundations of the polarized neutron phase shift experiment are discussed. The fact that the neutron retains its ground state throughout the experiment is shown to be crucial for the phase shift obtained.Comment: 7 pages, no figures ...
