Undulation instabilities in the meniscus of smectic membranes
J. C. Loudet, P. V. Dolganov, P. Patrício +2
Using optical microscopy, phase shifting interferometry and atomic force microscopy, we demonstrate the existence of undulated structures in the meniscus of ferroelectric smectic-C…
Two-dimensional dissipative solitons supported by localized gain
Yaroslav V. Kartashov, Vladimir V. Konotop, Victor A. Vysloukh
We show that the balance between localized gain and nonlinear cubic dissipation in the twodimensional nonlinear Schrodinger equation allows for existence of stable two-dimensional…
Dissipative periodic waves, solitons and breathers of the nonlinear Schrodinger equation with complex potentials
F. Kh. Abdullaev, V. V. Konotop, M. Salerno +1
Exact solutions for the generalized nonlinear Schrödinger (NLS) equation with inhomogeneous complex linear and nonlinear potentials are found. We have found localized and periodic…
Compactons in Nonlinear Schrödinger Lattices with Strong Nonlinearity Management
F. Kh. Abdullaev, P. G. Kevrekidis, M. Salerno
The existence of compactons in the discrete nonlinear Schrödinger equation in the presence of fast periodic time modulations of the nonlinearity is demonstrated. In the averaged DN…
The effect of polydispersity on the ordering transition of adsorbed self-assembled rigid rods
N. G. Almarza, J. M. Tavares, M. M. Telo da Gama
Extensive Monte Carlo simulations were carried out to investigate the nature of the ordering transition of a model of adsorbed self-assembled rigid rods on the bonds of a square la…
Three-dimensional rogue waves in non-stationary parabolic potentials
Zhenya Yan, V. V. Konotop, N. Akhmediev
Using symmetry analysis we systematically present a higher-dimensional similarity transformation reducing the (3+1)-dimensional inhomogeneous nonlinear Schrodinger (NLS) equation w…
Nonautonomous "rogons" in the inhomogeneous nonlinear Schrodinger equation with variable coefficients
Zhenya Yan
The analytical nonautonomous rogons are reported for the inhomogeneous nonlinear Schrödinger equation with variable coefficients in terms of rational-like functions by using the si…
Analytical three-dimensional bright solitons and soliton-pairs in Bose-Einstein condensates with time-space modulation
Zhenya Yan, Chao Hang
We provide analytical three-dimensional bright multi-soliton solutions to the (3+1)-dimensional Gross-Pitaevskii (GP) equation with time and space-dependent potential, time-depende…
Thresholdless surface solitons
Yuliy V. Bludov, Yaroslav V. Kartashov, Vladimir V. Konotop
We report on the existence of nonlinear surface waves which, on the one hand, do not require the threshold energy flow for their excitation, and, on the other hand, extend into med…
Dissipative defect modes in periodic structures
Yaroslav V. Kartashov, Vladimir V. Konotop, Victor A. Vysloukh +1
We show that periodic optical lattices imprinted in cubic nonlinear media with strong two-photon absorption and localized linear gain landscapes support stable dissipative defect m…
Dissipative surface solitons in periodic structures
Yaroslav V. Kartashov, Vladimir V. Konotop, Victor A. Vysloukh
We report dissipative surface solitons forming at the interface between a semi-infinite lattice and a homogeneous Kerr medium. The solitons exist due to balance between amplificati…
Scaling of the elastic contribution to the surface free energy of a nematic on a sawtoothed substrate
Jose Manuel Romero-Enrique, Chi-Tuong Pham, Pedro Patricio
We characterize the elastic contribution to the surface free energy of a nematic in presence of a sawtooth substrate. Our findings are based on numerical minimization of the Landau…
Control of the Bose-Einstein condensate by dissipation. Nonlinear Zeno effect
V. S. Shchesnovich, V. V. Konotop
We show that controlled dissipation can be used as a tool for exploring fundamental phenomena and managing mesoscopic systems of cold atoms and Bose-Einstein condensates. Even the…
Basis invariant conditions for supersymmetry in the two-Higgs-doublet model
P. M. Ferreira, Howard E. Haber, Joao P. Silva
The minimal supersymmetric standard model involves a rather restrictive Higgs potential with two Higgs fields. Recently, the full set of classes of symmetries allowed in the most g…
CP properties of symmetry-constrained two-Higgs-doublet models
P. M. Ferreira, M. Maniatis, O. Nachtmann +1
The two-Higgs-doublet model can be constrained by imposing Higgs-family symmetries and/or generalized CP symmetries. It is known that there are only six independent classes of such…
All-optical steering of light via spatial Bloch oscillations in a gas of three-level atoms
Chao Hang, V. V. Konotop
A standing-wave control field applied to a three-level atomic medium in a planar hollow-core photonic crystal waveguide creates periodic variations of linear and nonlinear refracti…
Renormalization-group constraints on Yukawa alignment in multi-Higgs-doublet models
P. M. Ferreira, L. Lavoura, Joao P. Silva
We write down the renormalization-group equations for the Yukawa-coupling matrices in a general multi-Higgs-doublet model. We then assume that the matrices of the Yukawa couplings…
Stability of the Einstein static universe in modified theories of gravity
Christian G. Boehmer, Lukas Hollenstein, Francisco S. N. Lobo +1
We present a brief overview of the stability analysis of the Einstein static universe in various modified theories of gravity, like f(R) gravity, Gauss-Bonnet or f(G) gravity, and…
