we propose a geometric phase gate in a decoherence - free subspace with trapped ions . the quantum information is encoded in the zeeman sublevels of the ground state and two physical qubits to make up one logical qubit with ultra long coherence time . single- and two - qubit operations together with the transport and s...

understanding the mechanism of electroweak symmetry breaking and the origin of boson and fermion masses is among the most pressing questions raised in contemporary particle physics . if these issues involve one ( several ) higgs boson(s ) , a precise measurement of all its ( their ) properties will be of prime importan...

the stochastic mutual repressor model is analysed using perturbation methods . this simple model of a gene circuit consists of two genes and three promotor states . either of the two protein products can dimerize , forming a repressor molecule that binds to the promotor of the other gene . when the repressor is bound t...

we compute the light hadron mass spectrum at @xmath0 using the @xmath1-improved sheikholeslami - wohlert ( sw ) fermion action with two choices of the clover coefficient : the classical value , @xmath2 , and a mean - field or tadpole - improved estimate @xmath3 . we compare our results with those of the gf11 collaborat...

kinetics of phase separation transition in boson - fermion cold atom mixtures is investigated . we identify the parameters at which the transition is governed by quantum nucleation mechanism , responsible for the formation of critical nuclei of a stable phase . we demonstrate that for low fermion - boson mass ratio the...

gauged @xmath0 model has been advocated for a long time in light of muon @xmath1 anomaly , which is a more than @xmath2 discrepancy between the experimental measurement and the standard model prediction . we augment this model with three right - handed neutrinos @xmath3 and a vector - like singlet fermion @xmath4 to ex...
