“…The background solution has been shown to satisfy type IIB supergravity field equations, given the parameters are related by the constraint q 2 + q2 = 1, where q and q are associated to the field strength of NS-NS fluxes and RR fluxes respectively. There have been multiple studies on various classical string solutions in detail in [54][55][56][57][58][59][60][61][62]. We study class of rigidly rotating strings and speculate its corresponding dual states in gauge theory in the mixed flux background.…”

Sigma model in AdS3× S3 background supported by both NS-NS and R-R fluxes is one of the most distinguished integrable models. We study a class of classical string solutions for N-spike strings moving in AdS3× S1 with angular momentum J in S1 ⊂ S5 in the presence of mixed flux. We observe that the addition of angular momentum J or winding number m results in the spikes getting rounded off and not end in cusp. The presence of flux shows no alteration to the rounding-off nature of the spikes. We also consider the large N-limit of N-spike string in AdS3× S1 in the presence of flux and show that the so-called Energy-Spin dispersion relation is analogous to the solution we get for the periodic-spike in AdS3− pp-wave ×S1 background with flux.

“…In the scope of this extended gravity, Yadav et al [33] have proposed the existence of non-exotic compact star, that validates the energy conditions and stability of the model. Biswas et al [34] have studied the anisotropic spherically symmetric strange star and have shown the validity of the conditions used in the model. Maurya et al [35] have suggested an embedded approach to study the existence of compact structures that describes anisotropic matter distributions in the framework of matter geome-try coupling.…”

In the work we present investigation on decoupling gravitational sources under the framework of f (R, T ) gravity. Basically the complete geometric deformation technique has been employed here which facilitates finding exact solutions to the anisotropic astrophysical system smoothly without imposing any particular ansatz for deformation function. Along with this we have also used 5-dimensional Euclidean spacetime in order to describe the embedding Class I spacetime for getting a solvable spherical physical system. The solutions thus obtained show physically interesting as well as viable with new possibilities to sought for. Especially, from the present investigation it is worthy to note that the mixture f (R, T ) + CGD translate the scenario beyond the pure GR realm and hence clearly helps to enhance the features of the interior astrophysical aspects of compact stellar objects. Therefore to check the physical acceptability and stability of the stellar system based on the obtained solutions, we have performed a few physical tests which satisfy all the stability criteria, including nonsingular nature of the density as well as pressure.

“…In this method, we find the dispersion relation between various conserved charges of semi-classical string dynamics in AdS space, which in turn gives the anomalous dimensions of the dual boundary field theory operators [4][5][6][7][8][9]. In particular, the study of rigidly rotating string in the large charge limit moving in some curved background has gained much attention in establishing the AdS/CFT holographic realization [10][11][12][13][14][15][16][17][18]. In order to have a better grasp on the spectrum of AdS 5 × S 5 superstring theories, various other class of classical string solutions has also been studied to a great extent.…”

We wish to construct an integrable Neumann-Rosochatius (NR) model of strings in AdS3 × S3 × S3 × S1 supported by pure NSNS flux. We observe that the forms of the Lagrangian and the Uhlenbeck integrals of motion of the considered system are NR-like with some suitable deformations, which eventually appear due to the presence of flux. We utilize the integrable framework of the deformed NR model to analyze rigidly rotating spiky strings moving only in S3 × S1. We further present a quantitative study on the rounding-off nature of the spike in the presence of non-zero angular momentum J in S1.
