New Cornell-led research is pointing the way toward an elusive goal of physicists—high-temperature superfluidity—by exploring excitons in atomically thin semiconductors. [30] After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. [29] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27]
