The exponential map of the group of area-preserving diffeomorphisms of a surface with boundary
James Benn, Gerard Misiolek, Stephen C. Preston
We prove that the Riemannian exponential map of the right-invariant metric on the group of volume-preserving diffeomorphisms of a two-dimensional manifold with a nonempty bou…
The mechanocaloric potential of spin crossover compounds
K. G. Sandeman
We present a first evaluation of the potential for spin crossover (SCO) compounds to be considered as a new class of giant mechanocaloric effect material. From literature data on t…
Potential Energy Landscape of the Apparent First-Order Phase Transition between Low-Density and High-Density Amorphous Ice
Nicolas Giovambattista, Francesco Sciortino, Francis W. Starr +1
The potential energy landscape (PEL) formalism is a valuable approach within statistical mechanics for describing supercooled liquids and glasses. Here we use the PEL formalism and…
Vector Approximate Message Passing
Sundeep Rangan, Philip Schniter, Alyson K. Fletcher
The standard linear regression (SLR) problem is to recover a vector from noisy linear observations . The approximate message pas…
Frustrated Magnetism and Caloric Effects in Mn-antiperovskite Nitrides: Theory
J. Zemen, E. Mendive Tapia, Z. Gercsi +4
We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised den…
Observation of structural universality in disordered systems using bulk diffusion measurement
Antonios Papaioannou, Dmitry S. Novikov, Els Fieremans +1
We report on an experimental observation of classical diffusion distinguishing between structural universality classes of disordered systems in one dimension. Samples of hyperunifo…
