Exciton Condensates in Electron-Hole Bilayers: A Guide

Researchers are achieving “perfect Coulomb drag” in dipolar excitonic insulators, a state of matter that allows for the frictionless transport of electrical charge. According to studies published in Science (2025) by Qi et al. and Nguyen et al., this phenomenon emerges from the interaction between electrons and holes in layered materials, potentially enabling a new … Read more

Controllable hydro-thermoelastic heat transport in ultrathin semiconductors at room temperature

The New Frontier of Heat Control: Beyond Traditional Thermodynamics For centuries, our understanding of heat has been governed by Fourier’s Law—the simple idea that heat flows from hot areas to cold areas in a predictable, diffusive manner. But in the realm of ultrathin semiconductors, the rules are changing. Recent breakthroughs in hydro-thermoelastic heat transport are … Read more
