By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new eviden...
Moving electrons around loops with light:A quantum device based on geometry
Moving electrons loops with light quantum device geometry
2016/3/2
While a classical bit found in conventional electronics exists only in binary one or zero states, the more resourceful quantum bit, or ‘qubit,’ is represented by a vector, pointing to a simultaneous c...
The criticism by W. E. Lamb, W. Schleich, M. Scully, C. Townes of a simplified quantum electrodynamics which represents the photon as a true particle is illustrated. Collisions being absent in low-pre...
Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses
2011/1/7
Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...

We propose and investigate a protocol for Gaussification of quantum states of traveling light
beams in an atomic quantum memory that couples to light via quantum non-demolition interaction.
The prot...

Light scattering oscillating dipole focused beam
2010/4/12
The interaction between a focused beam and a single classical oscillating dipole or a two-level system located at the focal spot is investigated. In particular, the ratio of the scattered to incident ...
