Eddy diffusivity of quasi-neutrally-buoyant inertial particles
Marco Martins Afonso, Paolo Muratore-Ginanneschi, Sílvio M. A. Gama +1
We investigate the large-scale transport properties of quasi-neutrally-buoyant inertial particles carried by incompressible zero-mean periodic or steady ergodic flows. We show how…
CP symmetry and thermal effects on Dirac bi-spinor spin-parity local correlations
A. E. Bernardini, V. A. S. V. Bittencourt, M. Blasone
Intrinsic quantum correlations supported by the structure of the Dirac equation used to describe particle/antiparticle states, optical ion traps and bilayer gr…
Giant magnons and spiky strings in the Schrodinger/dipole-deformed CFT correspondence
George Georgiou, Dimitrios Zoakos
We construct semi-classical string solutions of the Schrödinger spacetime, which is conjectured to be the gravity dual of a non-local dipole-deformed CFT. They a…
Valley polarized magnetic state in hole-doped mono layers of transition metal dichalcogenides
João E. H. Braz, B. Amorim, Eduardo V. Castro
We compute the valley/magnetic phase diagram of mono layers of transition metal dichalcogenides in the hole doped region where spin-orbit effects are particularly relevant. Taking…
The continuous rise of bulges out of galactic disks
I. Breda, P. Papaderos
(abridged) This study revolves around dmB, a new distance- and extinction-independent measure of the contribution by stellar populations older than 9 Gyr to the mean r-band surface…
Line-dependent veiling in very active T Tauri Stars
A. C. S. Rei, P. P. Petrov, J. F. Gameiro
The T Tauri stars with active accretion disks show veiled photospheric spectra. This is supposedly due to non-photospheric continuum radiated by hot spots beneath the accretion sho…
On the thickness of the double layer in ionic liquids
Anton Ruzanov, Meeri Lembinen, Pelle Jakovits +6
In this study, we examined the thickness of the electrical double layer (EDL) in ionic liquids using density functional theory (DFT) calculations and molecular dynamics (MD) simula…
Using the phase shift to asymptotically characterize the dipolar mixed modes in post-main-sequence stars
C. Jiang, J. Christensen-Dalsgaard, M. Cunha
Mixed modes have been extensively observed in post-main-sequence stars by the Kepler and CoRoT space missions. The mixture of the p and g modes can be measured by the dimensionless…
Distinguishing the albedo of exoplanets from stellar activity
L. M. Serrano, S. C. C. Barros, M. Oshagh +5
Light curves show the flux variation from the target star and its orbiting planets as a function of time. In addition to the transit features created by the planets, the flux also…
Revisiting concurrent separation logic
Pedro Soares, António Ravara, Simão Melo de Sousa
We present a new soundness proof of Concurrent Separation Logic (CSL) based on a structural operational semantics (SOS). We build on two previous proofs and develop new auxiliary n…
Synchrony Branching Lemma for Regular Networks
Pedro Soares
Coupled cell systems are dynamical systems associated to a network and synchrony subspaces, given by balanced colorings of the network, are invariant subspaces for every coupled ce…
The Lifting Bifurcation Problem on Feed-Forward Networks
Pedro Soares
We consider feed-forward networks, that is, networks where cells can be divided into layers, such that every edge targeting a layer, excluding the first one, starts in the prior la…
Settling velocity of quasi-neutrally-buoyant inertial particles
Marco Martins Afonso, Sílvio Marques de Almeida Gama
We investigate the sedimentation properties of quasi-neutrally buoyant inertial particles carried by incompressible zero-mean fluid flows. We obtain generic formulae for the termin…
The RoPES project with HARPS and HARPS-N. I. A system of super-Earths orbiting the moderately active K-dwarf HD 176986
A. Suárez Mascareño, J. I. González Hernández, R. Rebolo +12
We report the discovery of a system of two super-Earths orbiting the moderately active K-dwarf HD 176986. This work is part of the RoPES RV program of G- and K-type stars, which co…
On resolution of 1-dimensional foliations on 3-manifolds
Julio C. Rebelo, Helena Reis
This paper is devoted to the resolution of singularities of holomorphic vector fields and of one-dimensional holomorphic foliations in dimension 3 and it has two main objectives. F…
Dark energy, scalar singlet dark matter and the Higgs portal
Ricardo G. Landim
One of the simplest extensions of the Standard Model (SM) comprises the inclusion of a massive real scalar field, neutral under the SM gauge groups, to be a dark matter candidate.…
DC resistivity of quantum critical, charge density wave states from gauge-gravity duality
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In contrast to metals with weak disorder, the resistivity of weakly-pinned charge density waves (CDWs) is not controlled by irrelevant processes relaxing momentum. Instead, the lea…
On finitely generated submonoids of virtually free groups
Pedro V. Silva, Alexander Zakharov
We prove that it is decidable whether or not a finitely generated submonoid of a virtually free group is graded, introduce a new geometric characterization as quasi-geodesic monoid…
Radial coordinates for defect CFTs
Edoardo Lauria, Marco Meineri, Emilio Trevisani
We study the two-point function of local operators in the presence of a defect in a generic conformal field theory. We define two pairs of cross ratios, which are convenient in the…
Nonlinear optical responses of crystalline systems: Results from a velocity gauge analysis
D. J. Passos, G. B. Ventura, J. M. Viana Parente Lopes +2
In this work, the difficulties inherent to perturbative calculations in the velocity gauge are addressed. In particular, it is shown how calculations of nonlinear optical responses…
Stability of a heteroclinic network and its cycles: a case study from Boussinesq convection
Olga Podvigina, Sofia B. S. D. Castro, Isabel S. Labouriau
This article is concerned with three heteroclinic cycles forming a heteroclinic network in . The stability of the cycles and of the network are studied. The cycles a…
Cosmic Transients, Einstein's Equivalence Principle and Dark Matter Halos
Orfeu Bertolami, Ricardo G. Landim
Cosmic transients, such as gamma-ray bursts and fast radio bursts, have been used to constrain the Einstein's Equivalence Principle (EEP) through the parametrized-post-Newtonian (P…

M. Silva, A. Humphrey, P. Lagos +8
We present a detailed study of the kinematic, chemical and excitation properties of the giant Ly emitting nebula and the giant \ion{H}{I} absorber associated with the …
Deriving High-Precision Radial Velocities
Pedro Figueira
This chapter describes briefly the key aspects behind the derivation of precise radial velocities. I start by defining radial velocity precision in the context of astrophysics in g…
