Summary: In this paper, we study uncharged, non-conformal, and anisotropic systems with strong interactions using gauge-gravity duality. We obtain an anisotropic black brane solution to a 5D Einstein-Gauss-Bonnet-Axion-Dilaton system at finite temperature and investigate its properties. We also explore transport and diffusion properties and determine the imaginary part of the heavy quark potential in a strongly coupled plasma dual to Gauss-Bonnet gravity.

Summary: We propose a new approach to computing the supersymmetric partition function on closed five-manifolds by introducing a non-trivial fibration over the four-manifold and examining the Coulomb branch partition function. We match the low-energy effective field theory approach to explicit one-loop computations and discuss the effects of non-perturbative particles. We also provide evidence for the validity of the Lockhart-Vafa formula for the five-sphere partition function.

Summary: Building upon recent progress in compactifications of 6d (1, 0) superconformal field theories on Riemann surfaces to 4d N = 1 theories, this study systematically investigates the compactifications of 5d N = 1 SCFTs on Riemann surfaces to 3d N = 2 theories. By examining the compactification of rank 1 Seiberg ENf +1 SCFTs on tori and tubes with flux, various consistency checks are conducted on the resulting 3d theories, including matching IR symmetries and identifying operator spectra predicted by the 5d picture. The methods used in this study, which involve novel elements like Chern-Simons terms and monopole superpotentials, can also be applied to compactify other 5d SCFTs leading to 5d gauge theories.

Summary: The proposed method offers a systematic approach to computing the BPS spectrum of 5d/6d supersymmetric quantum field theories in Coulomb phases, utilizing blowup equations and the Omega background. It has been successfully applied to calculate the BPS spectra of various rank-1 and rank-2 5d Kaluza-Klein (KK) theories, with discussions on exotic cases such as new 5d SCFTs and the 5d SU(3)(8) gauge theory. These results serve as important checks for dualities among 5d theories and provide independent evidence for the existence of certain exotic theories.

Summary: This paper introduces a class of G-Sasaki manifolds with a reductive G-group action on their Kahler cones, proving the properness of K-energy on such manifolds and obtaining a sufficient and necessary condition for the existence of G-Sasaki-Einstein metrics. The results also apply to G-Sasaki-Ricci solitons, leading to the construction of many new examples through an established openness theorem.

Summary: Para-Ricci-like solitons with arbitrary potential on para-Sasaki-like Riemannian pi-manifolds are introduced and studied. The property of the studied soliton is determined by proving that its Ricci tensor is a constant multiple of the vertical component of both metrics. As a result, the corresponding scalar curvatures of the two considered metrics are equal and constant. Additionally, an explicit example of a Lie group as the manifold under study is provided.

Summary: In this study, the Seberg-Witten geometry of 5d N = 1 pure Yang-Mills theories compactified on a circle is explored, revealing multiple 4d limits of interacting Seiberg-Witten theories from a single 5d theory. The compactification leads to N copies of locally indistinguishable 4d pure SU(N) Seiberg-Witten theories in the infrared, glued together in a manner dictated by the Chern-Simons level.

Summary: This study identifies the 2d (0, 2) supersymmetric gauge theories corresponding to the classes of Y-p,Y-k(CP1 x CP1) and Y-p,Y-k(CP2) manifolds. The complex cones over these Sasaki-Einstein 7-manifolds are non-compact toric Calabi-Yau 4-folds. These infinite families of geometries are the largest ones for Sasaki-Einstein 7-manifolds whose metrics, toric diagrams, and volume functions are known explicitly. Therefore, this study presents the largest list of 2d (0, 2) supersymmetric gauge theories corresponding to Calabi-Yau 4-folds with known metrics.

Summary: This study revisits the construction of compactifying 6d SCFTs to 4d N=1 theories and explores it in detail from a 5d perspective using the box graph description of the extended Coulomb branch phases of 5d theories. This perspective may aid in understanding how to equivalently realize 4d N=1 models from geometric engineering in M-theory and recover various properties of the 4d theories from the 5d perspective.

Summary: The study initiates a general class of 2d N = (0, 2) quiver gauge theories, referred to as BFT2's, which are natural generalizations of Brane Brick Models. It explores how the dynamics and triality of the gauge theories translate into simple transformations of the underlying CW complexes, introducing various combinatorial tools for analysis. Additionally, the investigation delves into the connections of these theories with toric Calabi-Yau manifolds, emphasizing the importance of moduli space in identifying theories in the same triality class.

Summary: In this paper, a new class of para-Sasaki-like Riemannian manifolds are determined, and explicit examples are provided. A hyperbolic extension of a paraholomorphic paracomplex Riemannian manifold is defined and shown to be a para-Sasaki-like Riemannian manifold. Additionally, new examples of complete Einstein Riemannian manifolds of negative scalar curvature are presented.

Summary: We discuss the 5d AGT correspondence of supergroup gauge theories with A-type supergroups. We introduce two intertwiners called positive and negative intertwiners to compute the instanton partition function. The positive intertwiner is the ordinary Awata-Feigin-Shiraishi intertwiner while the negative intertwiner is an intertwiner obtained by using central charges with negative levels. We show that composition of them gives the basic Nekrasov factors appearing in supergroup partition functions. We explicitly derive the instanton partition functions of supergroup gauge theories with A and D-type quiver structures.

Summary: We use a combination of AdS/CFT and supersymmetric localization to study codimension-2 defects in 5d SCFTs and their gauge theory deformations. The results show a match between the defect free energies obtained from supersymmetric localization in the gauge theories and string theory results. This match is extended to defect RG flows.
