Direct Probe of Topological Order for Cold Atoms.
Direct Probe Topological Order Cold Atoms
2016/1/22
Cold-atom experiments in optical lattices offer a versatile platform to realize various topological quantum phases. A key challenge in those experiments is to unambiguously probe the topological order...
Avoid First Order Quantum Phase Transition by Changing Problem Hamiltonians
Quantum Phase Transition Changing Problem Hamiltonians
2010/10/29
The problem Hamiltonian of the adiabatic quantum algorithm for the maximum-weight independent set problem (MIS) that is based on the reduction to the Ising problem has flexible parameters. We show tha...
“Market making” behaviour in an electronic order book and its impact on the bid-ask spread
Market making behaviour electronic order book bid-ask spread

It has been suggested that marked point processes might be good candidates for the modeling of financial high-frequency data. A special class of point processes, Hawkes processes, has been the subject...
Studies on high order mode of bell-shaped prototype cavities

2009/8/14
Aluminium and copper prototype cavities were designed to study higher order modes (HOM). An automatic field mapping system was developed with LabVIEW to measure the radiofrequency (RF) characteristics...
February 15, 2007，Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may ...
