TL;DR: In this article, the scalar field couples to gravity in a nonminimal way, and it also couples to itself with the self-interacting potential solely determined by the metric ansatz.
Abstract: We obtain and analyze an exact solution to Einstein-Maxwell-scalar theory in ($2+1$) dimensions, in which the scalar field couples to gravity in a nonminimal way, and it also couples to itself with the self-interacting potential solely determined by the metric ansatz. A negative cosmological constant naturally emerges as a constant term in the scalar potential. The metric is static and circularly symmetric and contains a curvature singularity at the origin. The conditions for the metric to contain 0, 1, and 2 horizons are identified, and the effects of the scalar and electric charges on the size of the black hole radius are discussed. Under proper choices of parameters, the metric degenerates into some previously known solutions in ($2+1$)-dimensional gravity.

TL;DR: In this paper, it was shown that there exists a soliton-like solution for real scalar fields with U(1) charges, which is called I-ball, and whose stability is ensured by the adiabatic invariance for the oscillating field.
Abstract: We find that there exists a soliton-like solution ``I-ball'' in theories of a real scalar field if the scalar potential satisfies appropriate conditions Although the I-ball does not have any topological or global U(1) charges, its stability is ensured by the adiabatic invariance for the oscillating field

TL;DR: In this paper, the general exact form of the scalar field potential is found in the case of two and three fluids, and the analytic form is not found, but is obtained by quadratures.
Abstract: Starting from the hypothesis of scaling solutions, the general exact form of the scalar field potential is found In the case of two fluids, it turns out to be a negative power of hyperbolic sine In the case of three fluids the analytic form is not found, but is obtained by quadratures

TL;DR: In this article, an alternative approach, based on an effective field theory framework, for a new scalar that dominantly couples to one specific SM fermion mass eigenstate is described.
Abstract: New singlet scalar bosons have broad phenomenological utility and feature prominently in many extensions of the standard model. Such scalars are often taken to have Higgs-like couplings to SM fermions in order to evade stringent flavor bounds, e.g., by assuming minimal flavor violation (MFV), which leads to a rather characteristic phenomenology. Here, we describe an alternative approach, based on an effective field theory framework, for a new scalar that dominantly couples to one specific SM fermion mass eigenstate. A simple flavor hypothesis ensures adequate suppression of new flavor changing neutral currents. We consider radiatively generated flavor changing neutral currents and scalar potential terms in such theories, demonstrating that they are often suppressed by small Yukawa couplings, and also describe the role of $CP$ symmetry. We further demonstrate that such scalars can have masses that are significantly below the electroweak scale while still being natural, provided they are sufficiently weakly coupled to ordinary matter. In comparison to other flavor scenarios, our framework is rather versatile since a single (or a few) desired scalar couplings may be investigated in isolation. We illustrate this by discussing in detail the examples of an up-specific scalar mediator to dark matter and a muon-specific scalar that may address the $\ensuremath{\sim}3\ensuremath{\sigma}$ muon anomalous magnetic moment discrepancy.
