Propagation of active nematic-isotropic interfaces on substrates
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Motivated by results for the propagation of active-passive interfaces of bacterial Serratia marcescens swarms [Nat. Comm., 9, 5373 (2018)] we use a hydrodynamic multiphase model to…
Stability of neutral minima against charge breaking in the Higgs triplet model
P. M. Ferreira, B. L. Gonçalves
We analyse the possibility of charge breaking minima developing in the Higgs triplet model, and under what conditions they are deeper than charge-preserving ones. Analytical expres…
One-Loop Charge-Breaking Minima in the Two-Higgs Doublet Model
Pedro M. Ferreira, Logan A. Morrison, Stefano Profumo
We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacuua can coexist with charge breaking ones,…
Electroweak Corrections to Dark Matter Direct Detection in a Vector Dark Matter Model
S. Glaus, M. Mühlleitner, J. Müller +2
Although many astrophysical and cosmological observations point towards the existence of Dark Matter (DM), the nature of the DM particle has not been clarified to date. In this pap…
Living on the edge of instability
Artem Ryabov, Viktor Holubec, Ekaterina Berestneva
Statistical description of stochastic dynamics in highly unstable potentials is strongly affected by properties of divergent trajectories, that quickly leave meta-stable regions of…
Lattice-Boltzmann simulation of free nematic-isotropic interfaces
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use a hybrid method of lattice Boltzmann and finite differences to simulate flat and curved interfaces between the nematic and isotropic phases of a liquid crystal described by…
Aging in the long-range Ising model
Henrik Christiansen, Suman Majumder, Malte Henkel +1
The current understanding of aging phenomena is mainly confined to the study of systems with short-ranged interactions. Little is known about the aging of long-ranged systems. Here…
Single-file transport in periodic potentials: The Brownian asymmetric exclusion process
Dominik Lips, Artem Ryabov, Philipp Maass
Single-file Brownian motion in periodic structures is an important process in nature and technology, which becomes increasingly amenable for experimental investigation under contro…
Vacuum Instabilities in the N2HDM
P. M. Ferreira, Margarete Mühlleitner, Rui Santos +2
The Higgs sector of the Next-to-Minimal Two-Higgs-Doublet Model (N2HDM) is obtained from the Two-Higgs-Doublet Model (2HDM) containing two complex Higgs doublets, by adding a real…
Signal versus Background Interference in Signals for MSSM Benchmark Scenarios
Abdesslam Arhrib, Duarte Azevedo, Rachid Benbrik +4
In this paper, we investigate sizeable interference effects between a heavy charged Higgs boson signal produced via (+ c.c.) followed by the decay $H^-\to b\bar…
Active nematic-isotropic interfaces in channels
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use numerical simulations to investigate the hydrodynamic behavior of the interface between nematic (N) and isotropic (I) phases of a confined active liquid crystal. At low acti…
No strong violation up to the one-loop level in a two-Higgs-doublet model
P. M. Ferreira, L. Lavoura
We put forward a two-Higgs-doublet model, furnished with a symmetry, wherein is conserved in the dimension-four terms of the Lagrangian and is softly broken in the scala…
Impact of Inter-Country Distances on International Tourism
T. Verma, L. Rebelo, N. A. M. Araújo
Tourism is a worldwide practice with international tourism revenues increasing from US$495 billion in 2000 to US$1340 billion in 2017. Its relevance to the economy of many countr…
Enhanced propagation of motile bacteria on surfaces due to forward scattering
Stanislaw Makarchuk, Vasco C. Braz, Nuno A. M. Araújo +2
How motile bacteria move near a surface is a problem of fundamental biophysical interest and is key to the emergence of several phenomena of biological, ecological and medical rele…
Four-wave mixing in spin-orbit coupled Bose-Einstein condensates
Nguyen Viet Hung, Piotr Szankowski, Vladimir V. Konotop +1
We describe possibilities of spontaneous, degenerate four-wave mixing (FWM) processes in spin-orbit coupled Bose-Einstein condensates. Phase matching conditions (i.e., energy and m…
