Suppression and restoration of disorder-induced light localization mediated by PT-symmetry breaking
Yaroslav V. Kartashov, Chao Hang, Vladimir V. Konotop +3
We uncover that the breaking point of the PT-symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, wh…
Singlet Extensions of the Standard Model at LHC Run 2: Benchmarks and Comparison with the NMSSM
Raul Costa, Margarete Mühlleitner, Marco O. P. Sampaio +1
The Complex singlet extension of the Standard Model (CxSM) is the simplest extension that provides scenarios for Higgs pair production with different masses. The model has two inte…
Exactly solvable Wadati potentials in the PT-symmetric Gross-Pitaevskii equation
I. V. Barashenkov, D. A. Zezyulin, V. V. Konotop
This note examines Gross-Pitaevskii equations with PT-symmetric potentials of the Wadati type: . We formulate a recipe for the construction of Wadati potentials suppor…
Localised nonlinear modes in the PT-symmetric double-delta well Gross-Pitaevskii equation
I. V. Barashenkov, D. A. Zezyulin
We construct exact localised solutions of the PT-symmetric Gross-Pitaevskii equation with an attractive cubic nonlinearity. The trapping potential has the form of two -function…
One-loop contributions to neutral minima in the inert doublet model
P. M. Ferreira, Bogumila Swiezewska
The vacuum structure of the inert doublet model is analysed at the one-loop level using the effective potential formalism, to verify the validity of tree-level predictions for the…
Temperature (de)activated patchy colloidal particles
Daniel de las Heras, Margarida M. Telo da Gama
We present a new model of patchy particles in which the interaction sites can be activated or deactivated by varying the temperature of the system. We study the thermodynamics of t…
Flavour symmetries in a renormalizable SO(10) model
P. M. Ferreira, W. Grimus, D. Jurčiukonis +1
In the context of a renormalizable supersymmetric SO(10) Grand Unified Theory, we consider the fermion mass matrices generated by the Yukawa couplings to a $\mathbf{10} \oplus \mat…
Topological states in partially-PT-symmetric azimuthal potentials
Yaroslav V. Kartashov, Vladimir V. Konotop, Lluis Torner
We introduce partially-parity-time-symmetric (pPT-symmetric) azimuthal potentials composed from individual PT-symmetric cells located on a ring, where two azimuthal directions are…
Solitons in a nonlinear Schrodinger equation with PT-symmetric potentials and inhomogeneous nonlinearity: stability and excitation of nonlinear modes
Zhenya Yan, Zichao Wen, Vladimir V. Konotop
We report branches of explicit expressions for nonlinear modes in parity-time (PT) symmetric potentials of several types. For the single-well and double-well potentials the found s…
Relaxation dynamics of functionalized colloids on attractive substrates
C. S. Dias, C. Braga, N. A. M. Araujo +1
Particle-based simulations are performed to study the post-relaxation dynamics of functionalized (patchy) colloids adsorbed on an attractive substrate. Kinetically arrested structu…
Disease-induced resource constraints can trigger explosive epidemics
Lucas Böttcher, Olivia Woolley-Meza, Nuno A. M. Araújo +2
Advances in mathematical epidemiology have led to a better understanding of the risks posed by epidemic spreading and informed strategies to contain disease spread. However, a chal…
Dark solitons in dual-core waveguides with dispersive coupling
Yaroslav V. Kartashov, Vladimir V. Konotop, Boris A. Malomed
We report on new types of two-component one-dimensional dark solitons (DSs) in a model of a dual-core waveguide with normal group-velocity dispersion and Kerr nonlinearity in both…
Self-assembly of colloidal bands driven by a periodic external field
A. S. Nunes, N. A. M. Araujo, M. M. Telo da Gama
We study the formation of bands of colloidal particles driven by periodic external fields. Using Brownian dynamics, we determine the dependence of the band width on the strength of…
Nematic droplets at fibres
V. M. O. Batista, N. M. Silvestre, M. M. Telo da Gama
The emergence of new techniques for the fabrication of nematic droplets with nontrivial topology provides new routes for the assembly of responsive devices. Here we perform a numer…
Small-amplitude nonlinear modes under the combined effect of the parabolic potential, nonlocality and symmetry
Dmitry A. Zezyulin, Vladimir V. Konotop
We consider nonlinear modes of the nonlinear Schrödinger equation with a nonlocal nonlinearity and an additional PT-symmetric parabolic potential. We show that there exists a set o…
Undoubtable signs of CP-violation in Higgs decays at the LHC run 2
Duarte Fontes, Jorge C. Romão, Rui Santos +1
With the discovery of the Higgs boson at the Large Hadron Collider the high energy physics community's attention has now turned to understanding the properties of the Higgs boson,…
Prediction and control of slip-free rotation states in sphere assemblies
D. V. Stäger, N. A. M. Araújo, H. J. Herrmann
We study fixed assemblies of touching spheres that can individually rotate. From any initial state, sliding friction drives an assembly toward a slip-free rotation state. For bipar…
Preserving the validity of the Two-Higgs Doublet Model up to the Planck scale
P. M. Ferreira, Howard E. Haber, Edward Santos
We examine the constraints on the two Higgs doublet model (2HDM) due to the stability of the scalar potential and absence of Landau poles at energy scales below the Planck scale. W…
