LATTICE STABILITY AND SOFT MODES

Le Journal de Physique Colloques, 1982
Relationships between displacive phase transitions and soft modes are discussed and illustrated using experimental examples. Ferroelectric and ferroelastic transitions are dealed with together with the "band-Jahn-Teller" and antiferromagnetic transitions which are closely connected with acoustic soft modes.

Comparative Study of Magnetocaloric Properties for Gd^{3+} Compounds with Different Frustrated Lattice Geometries

PRX Energy, 2023
As materials with suppressed ordering temperatures and enhanced ground-state entropies, frustrated magnetic oxides are ideal candidates for cryogenic magnetocaloric refrigeration.

Soft background fields at next-to-leading power in transverse momentum dependent SIDIS with jets

Journal of High Energy Physics
We present a factorization formula for the e + h → e + jet + X cross section at small transverse momenta up to next-to-leading power (NLP), derived using the background field method (BFM) with explicit inclusion of soft modes.

Understanding thermalization in a non-Abelian gauge theory in terms of its soft modes

Physics Letters B
We measure the maximal Lyapunov exponent λL of physical states in a SU(2) gauge theory consisting of soft momentum modes both in and out-of-thermal equilibrium conditions using ab-initio lattice techniques.

Entanglement, soft modes, and celestial holography

Physical Review D
We evaluate the vacuum entanglement entropy across a cut of future null infinity for free Maxwell theory in four-dimensional Minkowski spacetime. The Weyl invariance of 4D Maxwell theory allows us to embed the Minkowski spacetime inside the Einstein static universe. The Minkowski vacuum can then be described as a thermofield double state on the (future)

Engineering ionic pathways by phonon-structure connection in perovskite solid electrolyte Li0.29La0.57TiO3

Communications Materials
Lithium lanthanum titanium oxide (LLTO) is a promising solid electrolyte (SE) for solid-state batteries, owing to its excellent chemical and thermal stability, wide electrochemical window, and high ionic conductivity even at room temperature.

Reprogrammable Soft Pneumatic Metamaterials with Multimodal Twisting and Tunable Multistability

Small Structures
Energy landscape and deformation modes endow soft pneumatic metamaterials with specific functionalities encoded by design. Their ability to perform tasks beyond their as‐designed functions, however, is currently limited by the invariant nature of their ...
