Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation [PDF]
, 2012 Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites
Advanced Functional Materials, EarlyView.The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

Solution of the Gardner problem on the lock-in range of phase-locked loop [PDF]
arXiv, 2017 The lock-in frequency and lock-in range concepts were introduced in 1966 by Floyd Gardner to describe the frequency differences of phase-locked loop based circuit for which the loop can acquire lock within one beat, i.e. without cycle slipping. These concepts became popular among engineering community and were given in various engineering publications.

Generation of Chinese-characters-like modes with transverse mode locked lasers [PDF]
arXiv, 2020 Spontaneous transverse mode locking to generate optical vortex arrays is already widely studied for the frequency degenerated transverse modes. While, the mode locking between transverse modes in different orders (non-frequency degenerated families) to achieve spatial stationary beam patterns is rarely reported. The theory of transverse mode locking is

The dynamics of phase locking [PDF]
, 2005 Many low-frequency phenomena such as the Madden-Julian oscillation (MJO) or the El Niño-Southern Oscillation (ENSO) exhibit rapid growth where they appear to be undergoing a phase locking with other time scales such as the annual cycle.
