Synchronous Rendezvous for Networks of Marine Robots in Large Scale Ocean Monitoring
Frontiers in Robotics and AI, 2019 We develop a synchronous rendezvous strategy for a network of minimally actuated mobile sensors or active drifters to monitor a set of Lagrangian Coherent Structure (LCS) bounded regions, each exhibiting gyre-like flows.

Construction of inflationary scenarios with the Gauss–Bonnet term and nonminimal coupling
European Physical Journal C: Particles and Fields, 2021 Inflationary models with a scalar field nonminimally coupled both with the Ricci scalar and with the Gauss–Bonnet term are studied. We propose the way of generalization of inflationary scenarios with the Gauss–Bonnet term and a scalar field minimally ...

Physical Review D, 2019 We conjecture that there exists a scalar bound state for every pair of fundamental fermions at a UV (`composite') scale, $Λ\gg v_{\text{weak}}$. This implies a large number of universally coupled, sub-critical Higgs doublets. All but the Standard Model Higgs are `dormant,' with large positive squared masses and each receives a small vacuum expectation ...

MIXING OF SCALAR GLUEBALL AND SCALAR QUARKONIA [PDF]
High Energy Physics, 2007 The isosinglet scalar mesons $f_0(1710)$, $f_0(1500)$, $f_0(1370)$ and their mixing are studied. Two recent lattice results are employed as the starting point; one is the approximate SU(3) symmetry in the scalar sector above 1 GeV for the connected insertion part without $q\bar q$ annihilation, and the other is the scalar glueball mass at 1710 MeV in ...

Scalarized Nutty Wormholes [PDF]
Symmetry, 2021 We construct scalarized wormholes with a NUT charge in higher curvature theories. We consider both Einstein-scalar-Gauss-Bonnet and Einstein-scalar-Chern-Simons theories, following Brihaye, Herdeiro and Radu, who recently studied spontaneously scalarised Schwarzschild-NUT solutions.

International Journal of Modern Physics B, 1994 We determine the excitations and S matrix of an integrable isotropic antiferromagnetic quantum spin chain of alternating spin 1/2 and spin 1. There are two types of gapless one-particle excitations: the usual spin 1/2 (“spinor”) kink, and a new spin 0 (“scalar”) kink.

SCALAR–SCALAR BOUND STATE IN NONCOMMUTATIVE SPACE [PDF]
Modern Physics Letters A, 2001 Bethe–Salpeter equation in the noncommutative space for a scalar–scalar bound state is considered. It is shown that in the nonrelativistic limit, the effect of spatial noncommutativity appears as if there exists a magnetic dipole moment coupled to each particle.

Generic scalar potentials in geometric scalar gravity [PDF]
Journal of Theoretical and Applied Physics, 2016 We discuss a generic form of the scalar potential appearing in the geometric scalar theory of gravity. We find the conditions on the potential by considering weak and strong gravity. The modified black hole solutions are obtained for generic potentials and the inverse problems on a black hole and on a spherical body (`pseudo-gravastar') are ...
