On the kinetic description of the objective molecular dynamics
Richard D. James, Kunlun Qi, Li Wang
In this paper, we develop a multiscale hierarchy framework for objective molecular dynamics (OMD), a reduced order molecular dynamics with a certain symmetry, that connects it to t…
Theory of Intermediate Twinning and Spontaneous Polarization in Ferroelectric Potassium Sodium Niobate
Georgios Grekas, Patricia-Lia Pop-Ghe, Eckhard Quandt +1
Potassium sodium niobate is considered a prominent material system as a substitute for lead-containing ferroelectric materials. It exhibits first-order phase transformations and fe…
Design of soft magnetic materials
Ananya Renuka Balakrishna, Richard D. James
We present a strategy for the design of ferromagnetic materials with exceptionally low magnetic hysteresis, quantified by coercivity. In this strategy, we use a micromagnetic algor…
New extremal inclusions and their applications to two-phase composites
Liping Liu, Richard James, Perry Leo
In this paper, we find a class of special inclusions that have the same property with respect to second order linear partial differential equations as holds for ellipsoids. That is…
A solution to the permalloy problem
Ananya Renuka Balakrishna, Richard D. James
We propose a solution to the longstanding permalloy problemwhy the particular composition of permalloy, FeNi, achieves a dramatic drop in hysteresis, while its…
A tool to predict coercivity in magnetic materials
Ananya Renuka Balakrishna, Richard D. James
Magnetic coercivity is often viewed to be lower in alloys with negligible (or zero) values of the anisotropy constant. However, this explains little about the dramatic drop in coer…
