DOI: 10.1080/17455030.2018.1524184
Abstract: ABSTRACT It is demonstrated that in Fourier domain the Navier–Stokes equations for an incompressible fluid can be reduced to a single complex scalar equation. An advantage of this equation is that any solution of this… read more here.

DOI: 10.1088/1475-7516/2018/11/023
Abstract: We study the correspondence between models of a self-interacting canonical complex scalar field and P(X)-theories/shift-symmetric k-essence. Both describe the same background cosmological dynamics, provided that the amplitude of the complex scalar is frozen modulo the… read more here.

Abstract: In this brief report, we investigate the existence of four-dimensional static spherically symmetric black holes (BHs) in the Einstein-complex-scalar-Gauss-Bonnet gravity with an arbitrary potential V(ϕ) and a coupling f(ϕ) between the scalar field ϕ and… read more here.

DOI: 10.1103/physrevd.104.044008
Abstract: It has been shown recently that the charged black hole can be scalarized if Maxwell field minimally couples with a complex scalar which has nonnegative nonlinear potential. We firstly prove that such scalarization cannot be… read more here.

DOI: 10.1103/physrevd.104.096011
Abstract: A model of two coupled complex scalar fields is studied at finite temperature and under an external magnetic field. The results are obtained in the context of the nonperturbative method of the optimized perturbation theory… read more here.

DOI: 10.1103/physrevd.97.015005
Abstract: We analyze the theoretical and phenomenological considerations for the electroweak phase transition and dark matter in an extension of the standard model with a complex scalar singlet (cxSM). In contrast with earlier studies, we use… read more here.
