From micro to macro: particle physics, gravity and cosmology
(Universidade Estadual Paulista (UNESP), 2019) [Tese de doutorado]In this thesis we review the particle content of our Universe and its cosmic evolution and show some new physics searches in these two areas. In Part I we present bounds on the energy scale of new physics and couplings of ... 
Finite time blowup and breaking of solitary wind waves
(Physical Review E, 2014) [Artigo]The evolution of surface water waves in finite depth under wind forcing is reduced to an antidissipative Kortewegde VriesBurgers equation. We exhibit its solitary wave solution. Antidissipation accelerates and increases ... 
Measurement of the differential cross sections for top quark pair production as a function of kinematic event variables in pp collisions at root s=7 and 8 TeV
(Physical Review D, 2016) [Artigo]Measurements are reported of the normalized differential cross sections for top quark pair production with respect to four kinematic event variables: the missing transverse energy; the scalar sum of the jet transverse ... 
Search for resonant t(t)overbar production in protonproton collisions at root s=8 TeV
(Physical Review D, 2016) [Artigo]A search is performed for the production of heavy resonances decaying into topantitop quark pairs in protonproton collisions at root s = 8 TeV. Data used for the analyses were collected with the CMS detector and correspond ... 
Shedding light on variational autoencoders
(Proceedings  2018 44th Latin American Computing Conference, CLEI 2018, 2018) [Trabalho apresentado em evento]Deep neural networks provide the canvas to create models of millions of parameters to fit distributions involving an equally large number of random variables. The contribution of this study is twofold. First, we introduce ... 
Femtoscopic Bose–Einstein correlations of charged hadrons in pp collisions at 13 tev in CmS∗ ∗∗
(Acta Physica Polonica B, Proceedings Supplement, 2019) [Artigo]Femtoscopic correlations between charged hadrons are measured for minimumbias and for highmultiplicity events in proton–proton collisions at s = 13 TeV. The results are based on data collected with the CMS experiment at ... 
Causal fasterthanlight travel from a localized second time coordinate
(Physical Review D, 2019) [Artigo]I present a general relativistic model with a compactified second time coordinate that a priori allows for causal, yet faster than light travel in the background of a FriedmannLemaîtreRobertsonWalker geometry, by local ... 
Weak coupling to unitarity crossover in BoseFermi mixtures: Mixingdemixing transition and spontaneous symmetry breaking in trapped systems
(Physical Review A, 2019) [Artigo]The usual treatment of a BoseFermi mixture relies on weakcoupling GrossPitaevskii (GP) and densityfunctional (DF) Lagrangians, often including the more realistic perturbative LeeHuangYang (LHY) corrections. We suggest ... 
Sduality, entropy function and transport in AdS 4 /CMT 3
(Journal of High Energy Physics, 2019) [Artigo]In this paper we consider Abelian vector plus scalar holographic gravity models for 2+1 dimensional condensed matter transport, and the effect of Sduality on them. We find the transport coefficients from the electric and ... 
Stable controllable giant vortex in a trapped BoseEinstein condensate
(Laser Physics Letters, 2019) [Artigo]In a harmonicallytrapped rotating BoseEinstein condensate (BEC), a vortex of large angular momentum decays to multiple vortices of unit angular momentum from an energetic consideration. We demonstrate the formation of a ... 
Octagons I: combinatorics and nonplanar resummations
(Journal of High Energy Physics, 2019) [Artigo]We explain how the ’t Hooft expansion of correlators of halfBPS operators can be resummed in a largecharge limit in N = 4 super YangMills theory. The full correlator in the limit is given by a nontrivial function of ...

Multipole expansion in generalized electrodynamics
(International Journal of Modern Physics A, 2019) [Artigo]In this paper, we study some classical aspects of Podolsky electrodynamics in the static regime. We develop the multipole expansion for the theory in both the electrostatic and the magnetostatic cases. We also address the ... 
Onedimensional bosonization and the SYK model
(Journal of High Energy Physics, 2019) [Artigo]We explore the possibility of extending the familiar bosonization of two dimensions to (0 + 1)dimensional systems with a large number of degrees of freedom. As an application of this technique, we consider a class of ... 
Particlevortex duality and theta terms in AdS/CMT applications
(Journal of High Energy Physics, 2019) [Artigo]In this paper we study particlevortex duality and the effect of theta terms from the point of view of AdS/CMT constructions. We can construct the duality in 2+1 dimensional field theories with or without a ChernSimons ... 
Limitation of the Lee–Huang–Yang interaction in forming a selfbound state in Bose–Einstein condensates
(Annals of Physics, 2019) [Artigo]The perturbative Lee–Huang–Yang (LHY) interaction proportional to n3∕2, where n is the density, creates an infinitely repulsive potential at the center of a Bose–Einstein condensate (BEC) with net attraction, which stops ... 
Conformal inflation with chameleon coupling
(Journal of Cosmology and Astroparticle Physics, 2019) [Artigo]We investigate the possibility that the inflaton, in particular in conformal inflation models, is also a chameleon, i.e. that it couples to the energy density of some heavy nonrelativistic matter present during inflation. ... 
Climate drivers of malaria at its southern fringe in the Americas
(PLoS ONE, 2019) [Artigo]In this work we analyze potential environmental drivers of malaria cases in Northwestern Argentina. We inspect causal links between malaria and climatic variables by means of the convergent cross mapping technique, which ... 
Asymptotic four point functions
(Journal of High Energy Physics, 2019) [Artigo]We initiate the study of fourpoint functions of large BPS operators at any value of the coupling. We do it by casting it as a sum over exchange of superconformal primaries and computing the structure constants using ... 
HalfBPS vertex operators of the AdS5 × S5 superstring
(Journal of High Energy Physics, 2019) [Artigo]Using the pure spinor formalism for the superstring in an AdS5 × S5 background, a simple expression is found for halfBPS vertex operators. At large radius, these vertex operators reduce to the usual supergravity vertex ...
