Three-point functions in AdS3/CFT2 holography

Journal of High Energy Physics, 2019
Recently, string theory on AdS3 × S3 × 𝕋4 with one unit of NS-NS flux (k = 1) was argued to be exactly dual to the symmetric orbifold of 𝕋 4, and in particular, the full (unprotected) spectrum was matched between the two descriptions.

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Tensionless AdS3/CFT2 and single trace T T ¯ $$ T\overline{T} $$

Journal of High Energy Physics
One of the few cases of AdS/CFT where both sides of the duality are under good control relates tensionless k = 1 strings on AdS3 to a two-dimensional symmetric product CFT. Building on prior observations, we propose an exact duality between string theory

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Non-differentiable multiobjective mixed symmetric duality under generalized convexity

Journal of Inequalities and Applications, 2011
The objective of this paper is to obtain a mixed symmetric dual model for a class of non-differentiable multiobjective nonlinear programming problems where each of the objective functions contains a pair of support functions.

Non-perturbative aspects of galileon duality

European Physical Journal C: Particles and Fields, 2018
We study quantum aspects of the galileon duality, especially in the case of a particular interacting galileon theory that is said to be dual to a free theory through the action of a simultaneous field and coordinate transformation.

Unexpected Asymmetric Mn‐Sb Site Mixing and Reentrant Spin‐Glass State of MnSb2Te4

Advanced Functional Materials, EarlyView.
MnSb2Te4 is an intrinsic magnetic topological insulator. Its properties are extraordinarily sensitive to tiny defects, making structural studies essential for understanding how magnetism and topology work together. This work shows that Mn can be unevenly distributed within the crystal and how that disorder is linked to a newly reported spin‐glass state

Tensionless strings on AdS3 orbifolds

Journal of High Energy Physics
The bound state of one NS5 brane (wrapped on a 𝕋4) and N NS1-branes has two dual descriptions: its low-energy dynamics is described by the symmetric orbifold of 𝕋4, while the near horizon geometry is captured by string theory on AdS3 × S3 × 𝕋4 with one ...

Chiral gauge theories and their applications [PDF]

, 1998
This thesis is concerned with so called chiral gauge theories, also known as self dual gauge theories. In particular, the aim of this thesis to investigate the role that chiral gauge theories play in duality symmetries in lower dimensions through ...
