Quantum mechanics powers lasers and precision measurements. A century-spanning perspective examines those successes and the ...

Physicists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a striking new form of quantum behavior. In star-shaped Kagome crystals—named after a ...

Scientists have shown that the two exponents (inelastic scattering exponent and dephasing exponent) commonly used to describe ...

Researchers at the University of Eastern Finland have uncovered two complementary mechanisms that govern coherence in ...

Researchers show that energy relaxation and loss of quantum coherence in gated graphene follow different processes, ...

Figure 1: To grasp the principal result of Niu and colleagues’ research, consider a device that raises a suspended weight in Earth’s gravitational field. Since both work and coherent ergotropy are ...

Quantum coherence and decoherence are fundamental indications of how well a system of quantum objects -- atoms or other quantum particles -- maintains its relationships and how reliably the ongoing ...

Excitons are particle-like entities that form when electrons bind to electron vacancies called holes. A long-standing goal in condensed-matter physics is the unambiguous creation of a collective ...

New research shows that the unique properties of atomic Bose-Einstein condensates extend to the internal spin states of the atoms from which the condensates are formed. Bose-Einstein condensates are ...
