Modeling the functional network of primary intercellular Ca wave propagation in astrocytes and its application to study drug effects
Marcelo Pires, Frank Raischel, Sandra Vaz +3
We introduce a simple procedure of multivariate signal analysis to uncover the functional connectivity among cells composing a living tissue and describe how to apply it for extrac…
Are There Hidden Scalars in LHC Higgs Results?
A. Arhrib, P. M. Ferreira, R. Santos
The Higgs boson recently discovered at the Large Hadron Collider has shown to have couplings to the remaining particles well within what is predicted by the Standard Model. The sea…
Gap solitons in the spin-orbit coupled Bose-Einstein condensates
Yaroslav V. Kartashov, Vladimir V. Konotop, Fatkhulla Kh. Abdullaev
We report a diversity of stable gap solitons in a spin-orbit coupled Bose-Einstein condensate subject to a spatially periodic Zeeman field. It is shown that the solitons, can be cl…
Conservative and PT-symmetric compactons in waveguide networks
A. V. Yulin, V. V. Konotop
Stable discrete compactons in arrays of inter-connected three-line waveguide arrays are found in linear and nonlinear limits in conservative and in parity-time PT symmetric models.…
Classical density functional theory for associating fluids in orienting external fields
B. D. Marshall, W. G. Chapman, M. M. Telo da Gama
We develop a classical density functional theory (DFT) for two site associating fluids in spatially uniform external fields which exhibit orientational inhomogeneities. The Helmhol…
Self-assembly in chains, rings and branches: a single component system with two critical points
Lorenzo Rovigatti, José Maria Tavares, Francesco Sciortino
We study the interplay between phase separation and self-assembly in chains, rings and branched structures in a model of particles with dissimilar patches. We extend Wertheim's fir…
Tunable nonlinear PT-symmetric defect modes with an atomic cell
Chao Hang, Dmitry A. Zezyulin, Vladimir V. Konotop +1
We propose a scheme of creating a tunable highly nonlinear defect in a one-dimensional photonic crystal. The defect consists of an atomic cell filled in with two isotopes of three-…
-symmetric coupler with nonlinearity
K. Li, D. A. Zezyulin, P. G. Kevrekidis +2
We introduce the notion of a -symmetric dimer with a nonlinearity. Similarly to the Kerr case, we argue that such a nonlinearity should be accessible in a pair…
Solitons in -symmetric periodic systems with the quadratic nonlinearity
F. C. Moreira, V. V Konotop, B. A. Malomed
We introduce a one-dimensional system combining the -symmetric complex periodic potential and the (second-harmonic-generating) nonlinearity. The imaginary p…
Localized modes in media with $\PT$-symmetric localized potential
F. C. Moreira, F. Kh. Abdullaev, V. V. Konotop +1
We study the existence and stability of solitons in the quadratic nonlinear media with spatially localized -symmetric modulation of the linear refractive index. Families…
Limits on strong FCNC top couplings at the LHC
Renato Guedes, Rui Santos, Miguel Won
The best limit on the strong FCNC anomalous couplings was obtained using the direct top production process at the Large Hadron Collider by the ATLAS collaboration. We perform a sim…
Parametric patterns in optical fiber ring nonlinear resonators
K. Staliunas, Chao Hang, V. V. Konotop
We propose that parametrically excited patterns, also known as Faraday patterns, can be observed in nonlinear fiber resonators, where the coefficient of Kerr nonlinearity is period…
Mixtures of functionalized colloids on substrates
Cristóvão Dias, Nuno Araújo, Margarida Telo da Gama
Patchy particles are a class of colloids with functionalized surfaces. Through surface functionalization, the strength and directionality of the colloidal interactions are tunable…
Trapping of light in solitonic cavities and its role in the supercontinuum generation
R. Driben, A. V. Yulin, A. Efimov +1
We demonstrate that the fission of higher-order N-solitons with a subsequent ejection of fundamental quasi-solitons creates solitonic cavities, formed by a pair of solitons with di…
Measuring the charged Higgs mass and distinguishing between models with top-quark observables
Saurabh D. Rindani, Rui Santos, Pankaj Sharma
We study the process of single-top production in association with a charged Higgs boson at the LHC and discuss how top-quark polarization and an azimuthal asymmetry of the ch…
Stationary modes and integrals of motion in nonlinear lattices with PT-symmetric linear part
Dmitry A. Zezyulin, Vladimir V. Konotop
We consider finite-dimensional nonlinear systems with linear part described by a parity-time (PT-) symmetric operator. We investigate bifurcations of stationary nonlinear modes fro…
Newton's cradles in optics: From to N-soliton fission to soliton chains
R. Driben, B. A. Malomed, A. V. Yulin +1
A mechanism for creating a Newton's cradle (NC) in nonlinear light wavetrains under the action of the third-order dispersion (TOD) is demonstrated. The formation of the NC structur…
Soliton interaction mediated by cascaded four wave mixing with dispersive waves
A. V. Yulin, R. Driben, B. A. Malomed +1
We demonstrate that trapping of dispersive waves between two optical solitons takes place when resonant scattering of the waves on the solitons leads to nearly perfect reflections.…
Avoiding Death by Vacuum
A. Barroso, P. M. Ferreira, I. Ivanov +2
The two-Higgs doublet model (2HDM) can have two electroweak breaking, CP-conserving, minima. The possibility arises that the minimum which corresponds to the known elementary parti…
Nonlinear modes in binary bosonic condensates with the pseudo-spin-orbital coupling
D. A. Zezyulin, R. Driben, V. V. Konotop +1
We consider a binary Bose-Einstein condensate (BEC) with nonlinear repulsive interactions and linear spin-orbit (SO) and Zeeman-splitting couplings. In the presence of the trapping…
Instabilities, solitons, and rogue waves in PT-coupled nonlinear waveguides
Yu. V. Bludov, R. Driben, V. V. Konotop +1
We considered the modulational instability of continuous-wave backgrounds, and the related generation and evolution of deterministic rogue waves in the recently introduced parity-t…
Computing the phase diagram of binary mixtures: a patchy particle case study
Lorenzo Rovigatti, Daniel de las Heras, José Maria Tavares +2
We investigate the phase behaviour of 2D mixtures of bi-functional and three-functional patchy particles and 3D mixtures of bi-functional and tetra-functional patchy particles by m…
Hybrid Bloch-Anderson localization of light
Simon Stutzer, Yaroslav V. Kartashov, Victor A. Vysloukh +4
We investigate the interplay of Bloch oscillations and Anderson localization in optics. Gradual washing out of Bloch oscillations and the formation of nearly stationary averaged in…
