Underdamped longitudinal soft modes in ionic crystallites—lattice and charge motions observed by ultrafast x-ray diffraction [PDF]
Soft modes in crystals are lattice vibrations with frequencies that decrease and eventually vanish as the temperature approaches a critical point, e.g., a structural change due to a phase transition.

Electrically Controlled Soft Actuators with Multiple and Reprogrammable Actuation Modes
New forms of soft actuators have enabled the construction of novel soft robots with various functionalities. Though previous researches have successfully fabricated soft actuators with diverse actuation modes, their actuation capabilities are often fixed

SOFT MODE CONTRIBUTION TO PATH INTEGRALS [PDF]
A method for nonperturbative path integral calculation is proposed. Quantum mechanics as the simplest example of a quantum field theory is considered. All modes are decomposed into hard (with frequencies [Formula: see text]) and soft (with frequencies [Formula: see text]) ones, where ω0 is some parameter.

Entanglement, soft modes, and celestial CFT
We revisit the calculation of vacuum entanglement entropy in free Maxwell theory in four-dimensional Minkowski spacetime. Weyl invariance allows for this theory to be embedded as a patch inside the Einstein static universe. We use conformal inversions to

Soft-Switched Three-Port DC-DC Converter With Simple Auxiliary Circuit
In this paper, a new high efficiency soft-switching non-isolated three-port converter (TPC) is proposed. In the conventional TPC, three switches are required to process power in different directions between inputs and output.

Soft edges: the many links between soft and edge modes [PDF]
Boundaries in gauge theory and gravity give rise to symmetries and charges at both finite and asymptotic distance. Due to their structural similarities, it is often held that soft modes are some kind of asymptotic limit of edge modes.

Temperature phase transitions in Rb2KRe3+F6 elpasolites - Raman spectroscopy study
Phase transitions in crystals of fluorine-containing elpasolites are investigated by Raman scattering spectroscopy. It was found that lattice instabilities in these crystals are induced by soft mode condensations, while restorations of these modes in ...

On the degenerated soft-mode instability [PDF]
We consider instabilities of a single mode with finite wavenumber in inversion symmetric spatially one dimensional systems, where the character of the bifurcation changes from sub- to supercritical behaviour. Starting from a general equation of motion the full amplitude equation is derived systematically and formulas for the dependence of the ...
