Parity-time-symmetric vector rational rogue wave solutions in any n-component nonlinear Schrödinger models
Guoqiang Zhang, Liming Ling, Zhenya Yan +1
The extreme events are investigated for an -component nonlinear Schrödinger (-NLS) system in the focusing Kerr-like nonlinear media, which appears in many physical fields. We…
Light Higgs searches in production at the LHC
Duarte Azevedo, Rodrigo Capucha, Emanuel Gouveia +2
In this paper we propose a new reconstruction method to explore the low mass region in the associated production of top-quark pairs () with a generic scalar boson () a…
Director alignment at the nematic-isotropic interface: elastic anisotropy and active anchoring
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Activity in nematics drives interfacial flows that lead to preferential alignment that is tangential or planar for extensile systems (pushers) and perpendicular or homeotropic for…
Nonlinearity-induced photonic topological insulator
Lukas J. Maczewsky, Matthias Heinrich, Mark Kremer +8
The hallmark feature of topological insulators renders edge transport virtually impervious to scattering at defects and lattice disorder. In our work, we experimentally demonstrate…
Stable two-dimensional soliton complexes in Bose-Einstein condensates with helicoidal spin-orbit coupling
Ya. V. Kartashov, E. Ya. Sherman, B. A. Malomed +1
We show that attractive two-dimensional spinor Bose-Einstein condensates with helicoidal spatially periodic spin-orbit coupling (SOC) support a rich variety of stable fundamental s…
Asymmetric perfect absorption and lasing of nonlinear waves by a complex -potential
Dmitry A. Zezyulin, Vladimir V. Konotop
Spectral singularities and the coherent perfect absorption are two interrelated concepts that have originally been introduced and studied for linear waves interacting with complex…
Symmetries of the 2HDM: an invariant formulation and consequences
P. M. Ferreira, B. Grzadkowski, O. M. Ogreid +1
Symmetries of the Two-Higgs-Doublet Model (2HDM) potential that can be extended to the whole Lagrangian, i.e. the CP-symmetries CP1, CP2, CP3 and the Higgs-family symmetries Z2, U(…
CP Violating Coupling in the Standard Model and Beyond
Da Huang, António P. Morais, Rui Santos
Inspired by the recent development in determining the property of the observed Higgs boson, we explore the -violating (CPV) cou…
Localization and delocalization of light in photonic moire lattices
Peng Wang, Yuanlin Zheng, Xianfeng Chen +5
Moire lattices consist of two identical periodic structures overlaid with a relative rotation angle. Present even in everyday life, moire lattices have been also produced, e.g., wi…
Radiative seesaw corrections and charged-lepton decays in a model with soft flavour violation
E. H. Aeikens, P. M. Ferreira, W. Grimus +2
We consider the one-loop radiative corrections to the light-neutrino mass matrix and their consequences for the predicted branching ratios of the five lepton-flavour-violating deca…
Wetting boundary conditions for multicomponent pseudopotential lattice Boltzmann
Rodrigo C. V. Coelho, Catarina B. Moura, Margarida M. Telo da Gama +1
The implementation of boundary conditions is among the most challenging parts of modeling fluid flow through channels and complex media. Here, we show that the existing methods to…
Cracking urban mobility
H. A. Carmona, A. W. T. de Noronha, A. A. Moreira +2
Assessing the resilience of a road network is instrumental to improve existing infrastructures and design new ones. Here we apply the optimal path crack model (OPC) to investigate…
Electroweak Corrections in a Pseudo-Nambu Goldstone Dark Matter Model Revisited
Seraina Glaus, Margarete Mühlleitner, Jonas Müller +3
Having so far only indirect evidence for the existence of Dark Matter a plethora of experiments aims at direct detection of Dark Matter through the scattering of Dark Matter partic…
Anomalies in Decays and Muon from Dark Loops
Da Huang, António P. Morais, Rui Santos
We explore a class of models which can provide a common origin for the recently observed evidence for lepton flavor universality violation in decays, the dark ma…
Heterogeneous impact of a lockdown on inter-municipality mobility
H. P. M. Melo, J. Henriques, R. Carvalho +3
Without a vaccine, the fight against the spreading of the coronavirus has focused on maintaining physical distance. To study the impact of such measures on inter-municipality traff…
Aging and equilibration in bistable contagion dynamics
Paul Richter, Malte Henkel, Lucas Böttcher
We analyze the late-time relaxation dynamics for a general contagion model. In this model, nodes are either active or failed. Active nodes can fail either "spontaneously" at any ti…
Boundedness of meta-conformal two-point functions in one and two spatial dimensions
Malte Henkel, Michal Dariusz Kuczynski, Stoimen Stoimenov
Meta-conformal invariance is a novel class of dynamical symmetries, with dynamical exponent , and distinct from the standard ortho-conformal invariance. The meta-conformal War…
The cell adaptation time sets a minimum length scale for patterned substrates
Diogo E. P. Pinto, Gonca Erdemci-Tandogan, M. Lisa Manning +1
The structure and dynamics of tissue cultures depend strongly on the physical and chemical properties of the underlying substrate. Inspired by previous advances in the context of i…
Smoluchowski equations for linker-mediated irreversible aggregation
J. M. Tavares, G. C. Antunes, C. S. Dias +2
In order to study linker-mediated aggregation of colloidal particles with limited valence, we combine kinetic Monte Carlo simulations and an approximate theory based on the Smoluch…
Scalar mass dependence of angular variables in production
Duarte Azevedo, Rodrigo Capucha, António Onofre +1
In this paper we explore CP discrimination in the associated production of top-quark pairs () with a generic scalar boson () at the LHC. We probe the CP-sensitivity of…
Vector Topological Edge Solitons in Floquet Insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Alexander Szameit +2
We introduce topological vector edge solitons in a Floquet insulator, consisting of two honeycomb arrays of helical waveguides with opposite directions of rotation in a focusing no…
Suppression of the Higgs Dimuon Decay
P. M. Ferreira, Marc Sher
It is often stated that elimination of tree-level flavor-changing neutral currents in multi-Higgs models requires that all fermions of a given charge to couple to the same Higgs bo…
Invasion Sandpile Model
M. N. Najafi, Z. Moghaddam, M. Samadpour +1
Motivated by multiphase flow in reservoirs, we propose and study a two-species sandpile model in two dimensions. A pile of particles becomes unstable and topples if, at least one o…
