Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor.
Metal-to-insulator transition—a process that turns materials from a conductor to an insulator—has been a crucial process behind microelectronic switches, nonvolatile memory, and neuromorphic computing materials. In many cases, ...
A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology.
Researchers at Princeton University have demonstrated the mechanics behind a key process in living cells, where liquid droplets form and carry out complex tasks within the intricate polymer scaffolds that crisscross the cells' ...
In 1960, Joaquin Luttinger introduced a universal statement that relates the total number of particles that a system can accommodate to its behavior under low-energy excitations. While Luttinger's theorem is readily verified ...
A team of physicists at the University of Cologne has solved a long-standing problem of condensed matter physics: they have directly observed the Kondo effect (the re-grouping of electrons in a metal caused by magnetic impurities) ...
We often crumple a scrap piece of paper into a ball before throwing it. This mundane action, however, creates a unique complex system with surprising mechanical properties. Take a thin plastic sheet such as cellophane and ...
In a new study, researchers from the University of California, Santa Barbara, (UCSB) have reported the discovery of a spin microemulsion in two-dimensional systems of spinor Bose-Einstein condensates, shedding light on a ...
The diamond in an engagement ring, the wonder-material graphene and the lead in a humble pencil are all formed from carbon, but display profoundly different characteristics. Carbon materials such as these are among the most ...
In a new study, scientists from the US and Taiwan have theoretically demonstrated the existence of a universal lower bound on topological entanglement entropy, which is always non-negative. The findings are published in the ...
