Could the LHC two-photon signal correspond to the heavier scalar in two-Higgs-doublet models?
P. M. Ferreira, Rui Santos, Marc Sher +1
LHC has reported tantalizing hints for a Higgs boson of mass 125 GeV decaying into two photons. We focus on two-Higgs-doublet Models, and study the interesting possibility that the…
Two-Dimensional Superfluid Flows in Inhomogeneous Bose-Einstein Condensates
Zhenya Yan, V. V. Konotop, A. V. Yulin +1
We report a novel algorithm of constructing linear and nonlinear potentials in the two-dimensional Gross-Pitaevskii equation subject to given boundary conditions, which allow for e…
Highly Entangled Photons and Rapidly Responding Polarization Qubit Phase Gates in a Room-Temperature Active Raman Gain Medium
Chao Hang, Guoxiang Huang
We present a scheme for obtaining entangled photons and quantum phase gates in a room-temperature four-state tripod-type atomic system with two-mode active Raman gain (ARG). We ana…
Macroscopic Zeno effect and stationary flows in nonlinear waveguides with localized dissipation
D. A. Zezyulin, V. V. Konotop, G. Barontini +1
We theoretically demonstrate the possibility to observe the macroscopic Zeno effect for nonlinear waveguides with a localized dissipation. We show the existence of stable stationar…
Light localization in nonuniformly randomized lattices
Yaroslav V. Kartashov, Vladimir V. Konotop, Victor A. Vysloukh +1
We address Anderson localization of light in disordered optical lattices where the disorder strength varies across the transverse direction. Such variation changes the preferred do…
The condensation and ordering of models of empty liquids
N. G. Almarza, J. M. Tavares, M. Simões +1
We consider a simple model consisting of particles with four bonding sites ("patches"), two of type A and two of type B, on the square lattice, and investigate its global phase beh…
Zeno effect and switching of solitons in nonlinear couplers
F. Kh. Abdullaev, V. V. Konotop, M. Ogren +1
The Zeno effect is investigated for soliton type pulses in a nonlinear directional coupler with dissipation. The effect consists in increase of the coupler transparency with increa…
Stability of localized modes in PT-symmetric nonlinear potentials
D. A. Zezyulin, Y. V. Kartashov, V. V. Konotop
We report on detailed investigation of the stability of localized modes in the nonlinear Schrodinger equations with a nonlinear parity-time (alias PT) symmetric potential. We are p…
Linear superpositions of gap solitons in periodic Kerr media
Yuliy V. Bludov, Vladimir V. Konotop, Mario Salerno
The existence of a novel type of solitons in periodic Kerr media constructed as superposition of noninteracting gap-solitons of different kinds (bright, dark and periodic) is first…
Nonlinear localized modes in dipolar Bose-Einstein condensates in optical lattices
S. Rojas-Rojas, R. A. Vicencio, M. I. Molina +1
The modulational instability and discrete matter wave solitons in dipolar BEC, loaded into a deep optical lattice, are investigated analytically and numerically. The process of mod…
Filling and wetting transitions of nematic liquid crystals on sinusoidal substrates
P. Patricio, N. M. Silvestre, C. -T. Pham +1
Close to sinusoidal substrates, simple fluids may undergo a filling transition, in which the fluid passes from a dry to a filled state, where the interface remains unbent but bound…
Theory and phenomenology of two-Higgs-doublet models
G. C. Branco, P. M. Ferreira, L. Lavoura +3
We discuss theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model. In general, these extensions have scalar mediated flavour changing neutra…
Symmetry breaking and multi-hump solitons in inhomogeneous gain landscapes
Yaroslav V. Kartashov, Vladimir V. Konotop, Victor A. Vysloukh
We address one-dimensional soliton formation in the cubic nonlinear medium with two-photon absorption and transversally inhomogeneous gain landscape consisting of a single or sever…
Light Charged Higgs bosons at the LHC in 2HDMs
Mayumi Aoki, Renato Guedes, Shinya Kanemura +3
We present a discussion of light charged Higgs boson searches at the Large Hadron Collider (LHC) in CP-conserving 2-Higgs Doublet Models (2HDMs). Taking into account all available…
Fourier mode dynamics for the nonlinear Schroedinger equation in one-dimensional bounded domains
J. G. Caputo, N. K. Efremidis, Chao Hang
We analyze the 1D focusing nonlinear Schrödinger equation in a finite interval with homogeneous Dirichlet or Neumann boundary conditions. There are two main dynamics, the collapse…
Linear and nonlinear Zeno effects in an optical coupler
F. Kh. Abdullaev, V. V. Konotop, V. S. Shchesnovich
It is shown that in a simple coupler where one of the waveguides is subject to controlled losses of the electric field, it is possible to observe optical analog of the linear and n…
Solitons in a medium with linear dissipation and localized gain
Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop
We present a variety of dissipative solitons and breathing modes in a medium with localized gain and homogeneous linear dissipation. The system posses a number of unusual propertie…
A soft origin for CKM-type CP violation
P. M. Ferreira, J. P. Silva, L. Lavoura
We present a two-Higgs-doublet model, with a $\mathbbm{Z}_3$ symmetry, in which CP violation originates solely in a soft (dimension-2) coupling in the scalar potential, and reveals…
The criticality of self-assembled rigid rods on triangular lattices
N. G. Almarza, J. M. Tavares, M. M. Telo da Gama
The criticality of self-assembled rigid rods on triangular lattices is investigated using Monte Carlo simulation. We find a continuous transition between an ordered phase, where th…
Phase diagrams of binary mixtures of patchy colloids with distinct numbers and types of patches: The empty fluid regime
Daniel de las Heras, José Maria Tavares, Margarida M. Telo da Gama
We investigate the effect of distinct bonding energies on the onset of criticality of low functionality fluid mixtures. We focus on mixtures of particles with two and three patches…
