Dynamics of Spontaneous Black Hole Scalarization and Mergers in Einstein-Scalar-Gauss-Bonnet Gravity. [PDF]
Physical Review Letters, 2021 We study the dynamics of black holes in scalar Einstein-Gauss-Bonnet theories that exhibit spontaneous black hole scalarization using recently introduced methods for solving the full, nonperturbative equations of motion.

Closing a spontaneous-scalarization window with binary pulsars [PDF]
Classical and quantum gravity, 2022 Benefitting from the unequaled precision of the pulsar timing technique, binary pulsars are important testbeds of gravity theories, providing some of the tightest bounds on alternative theories of gravity.

Interactive Multiobjective Procedure for Mixed Problems and Its Application to Capacity Planning
Entropy, 2021 A problem that appears in many decision models is that of the simultaneous occurrence of deterministic, stochastic, and fuzzy values in the set of multidimensional evaluations. Such problems will be called mixed problems.

Probing Modified Gravity Theories with Scalar Fields Using Black-Hole Images
Universe, 2023 We study a number of well-motivated theories of modified gravity with the common overarching theme that they predict the existence of compact objects, such as black holes and wormholes endowed with scalar hair.

Journal of Semantics, 2014 We present experimental evidence showing that there is considerable variation between the rates at which scalar expressions from different lexical scales give rise to Upper-Bounded construals. We investigated two factors that might explain the variation between scalar expressions: first, the availability of the lexical scales, which we measured on the ...

Scalar glueball, scalar quarkonia, and their mixing [PDF]
Physical Review D, 2006 The isosinglet scalar mesons $f_0(1710)$, $f_0(1500)$, $f_0(1370)$ and their mixing are studied. We employ two recent lattice results as the starting point; one is the isovector scalar meson $a_0(1450)$ which displays an unusual property of being nearly independent of quark mass for quark masses smaller than that of the strange, and the other is the ...

Nonconvex Vector Optimization and Optimality Conditions for Proper Efficiency
International Journal of Analysis and Applications, 2022 In this paper, we consider, a new nonlinear scalarization function in vector spaces which is a generalization of the oriented distance function. Using the algebraic type of closure, which is called vector closure, we introduce the algebraic boundary of a

Spin-Induced Black Hole Spontaneous Scalarization. [PDF]
Physical Review Letters, 2020 We study scalar fields in a black hole background and show that, when the scalar is suitably coupled to curvature, rapid rotation can induce a tachyonic instability.

Spontaneous nonlinear scalarization of Kerr black holes [PDF]
Physical Review D, 2022 As it became well known in the past years, Einstein-scalar-Gauss-Bonnet (EsGB) theories evade no-hair theorems and allow for scalarized compact objects including black holes (BH). The coupling function that defines the theory is the main character in the
