closed prolongation, one-dimensional optimal systems and nonlocal conservation
laws of the coupled... | 1501.03580v1 |
2015-05-05 | Reciprocal link for a coupled Camassa-Holm type equation | A coupled Camassa-Holm type equation is linked to the first negative flow of
a modified Drinfeld-Sokolov III hierarchy by a transformation of reciprocal

unsynchronized state to a state of complete synchronization under the influence
of the co... | 1505.01090v1 |
2015-05-07 | Coupled SU(3)-structures and Supersymmetry | We review coupled ${\rm SU}(3)$-structures, also known in the literature as
restricted half-flat structures, in relation to supersymmetry. In particular,
we study special classes of examples admitting such structures and the
behaviour of flows of ${\rm SU}(3)$-structures with respect to the coupled
condition. | 1505.01655v1 |
2015-05-29 | A coupled-channel formalism for three-body final state interaction | From dispersion relation approach, a formalism that describes final state
interaction among three particles in a coupled-channel system is presented in
this work. Different representations of coupled-channel three-body formalism

2015-10-19 | Transient dynamics of pulse-coupled oscillators with nonlinear charging curves | We consider the transient behavior of globally coupled systems of identical
pulse coupled oscillators. Synchrony develops through an aggregation
phenomenon, with clusters of synchronized oscillators forming and growing
larger in time. Previous work derived expressions for these time dependent
clusters, when each oscill... | 1510.05341v2 |
2015-10-28 | Triple Higgs coupling in the most general 2HDM at SM-like scenario | We consider the triple Higgs coupling for $h(125)$ Higgs boson within the
most general 2HDM. At moderate values of parameters of model, allowing by
modern data, noticeable deviation of this coupling from its SM value is
improbable. This deviation can be sizable only if some measurable parameters of
the model are exotic... | 1510.08270v3 |
2015-10-31 | Deep-subwavelength magnetic-coupling-dominant stereometamaterials | Here, we experimentally demonstrate that a stack of metallic spiral
structures (MSSs) can have dominant magnetic coupling in both of its two
configurations. This allows magnetic-coupling-dominant energy transport along a
one-dimensional stack of MSSs at a deep-subwavlength scale, as demonstrated
with near-field transmi... | 1511.00072v1 |
2015-11-13 | Cluster synchronization of starlike networks with normalized Laplacian coupling: master stability function approach | A generalized model of starlike network is suggested that takes into account
non-additive coupling and nonlinear transformation of coupling variables. For
this model a method of analysis of synchronized cluster stability is developed.
Using this method three starlike networks based on Ikeda, predator-prey and

products) as well as projections of Poisson brackets to less detailed Poisson
brackets. This w... | 1607.02023v2 |
2016-07-27 | Darboux transformations and exact soliton solutions of integrable coupled spin systems related with the Manakov system | We construct a Darboux transformation of a general $su(3)$-valued spin system
called the $\Gamma$-spin system. Using this Darboux transformation we derive a

2017-02-02 | Exponential stability for a coupled system of damped-undamped plate equations | We consider the transmission problem for a coupled system of undamped and
structurally damped plate equations in two sufficiently smooth and bounded
subdomains. It is shown that, independently of the size of the damped part, the
damping is strong enough to produce uniform exponential decay of the energy of
the coupled ... | 1702.00637v1 |
2010-05-17 | Noise-Induced Synchronization of a Large Population of Globally Coupled Nonidentical Oscillators | We study a large population of globally coupled phase oscillators subject to
common white Gaussian noise and find analytically that the critical coupling
strength between oscillators for synchronization transition decreases with an
increase in the intensity of common noise. Thus, common noise promotes the
onset of sync... | 1005.2833v1 |
2013-08-09 | Probing the nature of the Higgs-gluon coupling | One and two-jet observables of dimension-7 Higgs-gluon coupling operators are
studied as probes of possible deviations from the top-loop induced gluon-Higgs
coupling. We discuss the case of both a scalar as well as a pseudo-scalar Higgs
boson and show that higher order operators can give visible deviations from

models which predict more t... | 1403.2309v2 |
2014-03-25 | Comment on `Self-organized cooperative criticality in coupled complex systems' | In a recent Letter (EPL 105, 40006; arXiv:1309.7107), Liu and Hu presented a
model of toppling-coupled sandpiles, where they found that the avalanche
exponents for two toppling-coupled sandpiles are the same as those for a single
uncoupled sandpile. In this Comment we provide a proof of this observation for
the case wh... | 1403.6424v1 |
2017-01-21 | Optomechanical Microwave Quantum Illumination in Weak Coupling Regime | We propose to realize microwave quantum illumination in weak coupling regime
based on multimode optomechanical systems. In our proposal the multimode
together with a frequency-mismatch process could reduce mechanical thermal
noise. Therefore, we achieve a significant reduction of error probability than
