Physicists from Trinity College Dublin and the Universidad Complutense of Madrid have made a peculiar discovery in which energy moves from a colder to a hotter region. They describe how a quantum effect forces current passing through a piece of matter to flow around its edges and sometimes against the typical direction of heat transfer. The work could eventually inspire new methods for controlling the flow of energy through nanoscale structures, which could have applications in materials science and computing with better performance and sustainability in mind.

“Science by Simulation” is a recipe book of mathematical models that can be enlivened by the transmutation of equations into computer code. An eclectic mix of scenarios in twelve independent chapters provides a diverse set of contexts and stories to help incentivize the acquisition of key skills in applied mathematics.
U.S. Naval Research Laboratory scientists and Naval Research Enterprise Internship Program (NREIP) intern collect output data of natural convection between water and air exhibiting Rayleigh-Bénard instabilities to test the power of novel algorithms to significantly reduce time and costs of simulating the behavior of complex multiphysics systems with machine learning.

Henry Yuen, assistant professor of computer science, has won a National Science Foundation CAREER Award to advance quantum information science. With the five-year, $675,000 grant, awarded to junior faculty in support of early-career development, Yuen will advance and connect multiple facets of quantum information theory, theoretical computer science, and pure mathematics. The work will help solve fundamental problems and has applications in areas including quantum device validation and quantum cryptography.
