Cell division sets a universal flow geometry in cell layers
Tianxiang Ma, Lasse Bonn, Valeriia Grudtsyna +4
Collective flows in epithelial tissues contain a geometric backbone of vortical interfaces whose statistics exhibit hallmarks of critical percolation and conformal invariance. Yet…
Observation of linear and nonlinear light localization at the edges of moiré lattices
A. A. Arkhipova, Y. V. Kartashov, S. K. Ivanov +11
We observe linear and nonlinear light localization at the edges and in the corners of truncated moiré lattices created by the superposition of periodic mutually-twisted at Pythagor…
Lepton Flavor Specific Extended Higgs Model
B. L. Gonçalves, Matthew Knauss, Marc Sher
In extended Higgs models, a discrete symmetry is needed in the quark sector to avoid tree-level flavor-changing neutral currents. However, this is not necessary the case in the lep…
Collider phenomenology of new neutral scalars in a flavoured multi-Higgs model
Pedro M. Ferreira, João Gonçalves, António P. Morais +3
In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signa…
Non-equilibrium relaxations: ageing and finite-size effects
Malte Henkel
The long-time behaviour of spin-spin correlators in the slow relaxation of systems undergoing phase-ordering kinetics is studied in geometries of finite size. A phenomenological fi…
Body and mind: Decoding the dynamics of pedestrians and the effect of smartphone distraction by coupling mechanical and decisional processes
Iñaki Echeverría-Huarte, Alexandre Nicolas
Pedestrians are able to anticipate, which gives them an edge in avoiding collisions and navigating in cluttered spaces. However, these capabilities are impaired by digital distract…
Collective transport of droplets through porous media
Rodrigo C. V. Coelho, Danilo P. F. Silva, António M. R. Maschio +2
The flow of deformable particles, such as droplets, dragged by a fluid, through a network of narrow pores inside rocks or other porous media is key in a range of applications, from…
Softly broken symmetries in the 2HDM -- an invariant formulation
Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1
Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separatio…
Mechanochemical Active Ratchet
Artem Ryabov, Mykola Tasinkevych
Self-propelled nanoparticles moving through liquids offer the possibility of creating advanced applications where such nanoswimmers can operate as artificial molecular-sized motors…
Impact of electroweak group representation in models for and anomalies from Dark Loops
Rodrigo Capucha, Da Huang, Tomás Lopes +1
We discuss two models which are part of a class providing a common explanation for lepton flavor universality violation in decays, the dark matter (DM) problem a…
Direct detection of pseudo-Nambu-Goldstone dark matter in a two Higgs doublet plus singlet extension of the SM
Thomas Biekötter, Pedro Gabriel, María Olalla Olea-Romacho +1
We calculate the leading radiative corrections to the dark-matter-nucleon scattering in the pseudo-Nambu-Goldstone dark matter model augmented with a second Higgs doublet (S2HDM).…
Vector valley Hall edge solitons in superhoneycomb lattices
Qian Tang, Yiqi Zhang, Yaroslav V. Kartashov +2
Topological edge solitons that bifurcate and inherit topological protection from linear edge states and, therefore, demonstrate immunity to disorder and defects upon propagation, a…
Localization of ultracold atoms in incommensurate spin-orbit-coupling and Zeeman lattices
Dmitry A. Zezyulin, Vladimir V. Konotop
We consider a particle governed by a one-dimensional Hamiltonian in which artificial periodic spin-orbit coupling and Zeeman lattice have incommensurate periods. Using best rationa…
P-even, CP-violating Signals in Scalar-Mediated Processes
Howard E. Haber, Venus Keus, Rui Santos
Most studies of Higgs sector CP violation focus on the detection of CP-violating neutral Higgs-fermion Yukawa couplings, which yield P-odd, CP-violating phenomena. There is some li…
Diffusion coefficient and power spectrum of active particles with a microscopically reversible mechanism of self-propelling
Artem Ryabov, Mykola Tasinkevych
Catalytically active macromolecules are envisioned as key building blocks in development of artificial nanomotors. However, theory and experiments report conflicting findings regar…
Electroweak Corrections to Dark Matter Direct Detection in the Dark Singlet Phase of the N2HDM
Seraina Glaus, Margarete Mühlleitner, Jonas Müller +2
Direct detection experiments are the only way to obtain indisputable evidence of the existence of dark matter (DM) in the form of a particle. These experiments have been used to pr…
One-loop Corrections to the Higgs Boson Invisible Decay in a Complex Singlet Extension of the SM
Felix Egle, Margarete Mühlleitner, Rui Santos +1
The search for dark matter (DM) at colliders is founded on the idea of looking for something invisible. There are searches based on production and decay processes where DM may reve…
Quantum dynamics far from equilibrium: a case study in the spherical model
Malte Henkel
The application of quantum Langevin equations for the study of non-equilibrium relaxations is illustrated in the exactly solved quantum spherical model. Tutorial sections on the ph…
Dispersion of activity at an active-passive nematic interface
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Efficient nutrient mixing is crucial for the survival of bacterial colonies and other living systems. This raises the question of whether the optimization of mixing through the eme…
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…

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…
