Meta-Schrödinger invariance
Stoimen Stoimenov, Malte Henkel
The Meta-Schrödinger algebra arises as the dynamical symmetry in transport processes which are ballistic in a chosen `parallel' direction and diffusive and all other `transverse' d…
Benchmarking Di-Higgs Production in Various Extended Higgs Sector Models
Hamza Abouabid, Abdesslam Arhrib, Duarte Azevedo +4
We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet…
Perfectly absorbed and emitted currents by complex potentials in nonlinear media
Dmitry A. Zezyulin, Vladimir V. Konotop
Recently it was demonstrated that the concept of a spectral singularity (SS) can be generalized to waves propagating in nonlinear media, like matter waves or electromagnetic waves…
An improved multicomponent pseudopotential lattice Boltzmann method for immiscible fluid displacement in porous media
M. Sedahmed, R. C. V. Coelho, H. A. Warda
Immiscible fluid displacement in porous media occurs in several natural and industrial processes. For example, during petroleum extraction from porous rock reservoirs, water is use…
Dynamics of two-dimensional liquid bridges
Rodrigo C. V. Coelho, Luis A. R. G. Cordeiro, Rodrigo B. Gazola +1
We have simulated the motion of a single vertical, two-dimensional liquid bridge spanning the gap between two flat, horizontal solid substrates of given wettabilities, using a mult…
Floquet Edge Multicolor Solitons
Sergey K. Ivanov, Yaroslav V. Kartashov, Alexander Szameit +2
Topological insulators are unique physical structures that are insulators in their bulk, but support currents at their edges which can be unidirectional and topologically protected…
Superexponential amplification, power blowup, and solitons sustained by non-Hermitian gauge potentials
Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop
We introduce a continuous one-dimensional non-Hermitian matrix gauge potential and study its effect on dynamics of a two-component field. The model is emulated by a system of evane…
Nonlinear Thouless pumping: solitons and transport breakdown
Qidong Fu, Peng Wang, Yaroslav V. Kartashov +2
One-dimensional topological pumping of matter waves in two overlaid optical lattices moving with respect to each other is considered in the presence of attractive nonlinearity. It…
The hidden side of scalar-triplet models with spontaneous CP violation
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim
Scalar triplet extensions of the Standard Model provide an interesting playground for the explanation of neutrino mass suppression through the type-II seesaw mechanism. Propelled b…
Impact of SM parameters and of the vacua of the Higgs potential in gravitational waves detection
Felipe F. Freitas, Gabriel Lourenço, António P. Morais +5
In this work we discuss two different phases of a complex singlet extension of the Standard Model (SM) together with an extension that also includes new fermion fields, in particul…
Ultralight bosons for strong gravity applications from simple Standard Model extensions
Felipe F. Freitas, Carlos A. R. Herdeiro, António P. Morais +5
We construct families, and concrete examples, of simple extensions of the Standard Model that can yield ultralight {real or} complex vectors or scalars with potential astrophysical…
Inheritances, social classes, and wealth distribution
Pedro Patrício, Nuno A. M. Araújo
We consider a simple theoretical model to investigate the impact of inheritances on the wealth distribution. Wealth is described as a finite resource, which remains constant over d…
A three Higgs doublet model with symmetry-suppressed flavour changing neutral currents
Dipankar Das, P. M. Ferreira, António P. Morais +3
We construct a three-Higgs doublet model with a flavour non-universal symmetry. That symmetry induces suppressed flavour-changing interactions media…
Topological dipole Floquet solitons
Sergey K. Ivanov, Yaroslav V. Kartashov, Matthias Heinrich +3
We theoretically introduce a new type of topological dipole solitons propagating in a Floquet topological insulator based on a kagome array of helical waveguides. Such solitons bif…
One-loop Corrections to the Higgs Boson Invisible Decay in the Dark Doublet Phase of the N2HDM
Duarte Azevedo, Pedro Gabriel, Margarete Muhlleitner +2
The Higgs invisible decay width may soon become a powerful tool to probe extensions of the Standard Model with dark matter candidates at the Large Hadron Collider. In this work, we…
Metastable two-component solitons near an exceptional point
Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop
We consider a two-dimensional nonlinear waveguide with distributed gain and losses. The optical potential describing the system consists of an unperturbed complex potential dependi…
in the 2HDM and slightly beyond -- an updated view
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim +1
The recent measurement of the muon anomaly continues to defy a Standard Model explanation, but can be accommodated within the framework of two Higgs doublet models. If one…
Binary Mixtures of Locally Coupled Mobile Oscillators
Gonçalo Paulo, Mykola Tasinkevych
We study synchronization dynamics in binary mixtures of locally coupled Kuramoto oscillators which perform Brownian motion in a two-dimensional box. We introduce two models, where…
Wound opening in a thin incompressible viscoelastic tissue
G. M. Carvalho, N. A. M. Araújo, P. Patrício
We develop a model to investigate analytically and numerically the mechanics of wound opening made in a viscoelastic, isotropic, homogeneous, and incompressive thin tissue. This pr…
Enhanced diffusivity in microscopically reversible active matter
Artem Ryabov, Mykola Tasinkevych
Physics of self-propelled objects at the nanoscale is a rapidly developing research field where recent experiments focused on motion of individual catalytic enzymes. Contrary to th…
