Underdamped longitudinal soft modes in ionic crystallites—lattice and charge motions observed by ultrafast x-ray diffraction [PDF]
Structural Dynamics, 2022 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.

Entanglement, soft modes, and celestial CFT
Journal of High Energy PhysicsWe 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

Temperature phase transitions in Rb2KRe3+F6 elpasolites - Raman spectroscopy study
Materials and Devices, 2021 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 ...

Consistent treatment of rapidity divergence in soft-collinear effective theory
Journal of High Energy Physics, 2021 In soft-collinear effective theory, we analyze the structure of rapidity divergence due to the collinear and soft modes residing in disparate phase spaces.

Anomalous enhancement of dilepton production due to soft modes in dense quark matter [PDF]
EPJ Web of Conferences, 2023 We explore how the dilepton production rate is modified near the critical temperature of color superconductivity and QCD critical point by the soft modes inherently associated with the phase transitions of second-order.

On the degenerated soft-mode instability [PDF]
Journal of Physics A: Mathematical and General, 1998 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 ...

Clustering Categorical Data: Soft Rounding K-Modes
Information and Computation, 2023 Over the last three decades, researchers have intensively explored various clustering tools for categorical data analysis. Despite the proposal of various clustering algorithms, the classical k-modes algorithm remains a popular choice for unsupervised learning of categorical data.
