Direct imaging of active orbitals in quantum materials

In quantum materials based on transition metals, rare-earth and actinide elements, electronic states are characterized by electrons in orbitals d and f, combined with the solid's strong band formation. Until now, to estimate ...

Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

Learning more about phase transitions in small systems

(PhysOrg.com) -- "People want to understand phase transitions in a finite system by quantum simulation," Luming Duan tells PhysOrg.com. Duan is a professor at the University of Michigan, located in Ann Arbor. "Being able ...

Water and quantum magnets share critical physics

In physics, things exist in phases, such as solid, liquid and gas states. When something crosses from one phase to another, we talk about a phase transition—like water boiling into steam, turning from liquid to gas.
