How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Nationalism and the transformation of the state
Nations and Nationalism, Volume 30, Issue 3, Page 380-396, July 2024.Abstract While it is often assumed that the core debates about nationalism were settled by modernist scholars already in the 1980s, there are reasons to question this theoretical ‘consensus’, especially because it fails to anticipate the wave of nationalist geopolitics that is currently sweeping through the world.

Locality and causality properties of light cone string field theory [PDF]
, 2004 The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Superstring Holography and Integrability in AdS₅ x S⁵ [PDF]
, 2005 The AdS/CFT correspondence provides a rich testing ground for many important topics in theoretical physics. The earliest and most striking example of the correspondence is the conjectured duality between the energy spectrum of type IIB superstring ...

Gauge theory description of compactified pp-waves [PDF]
, 2003 We find a new Penrose limit of AdS(5) x S-5 that gives the maximally symmetric pp-wave background of type-IIB string theory in a coordinate system that has a manifest space-like isometry. This induces a new pp-wave/gauge-theory duality which on the gauge

Semiclassical strings in supergravity PFT [PDF]
, 2014 Puff field theory (PFT) is an example of a non-local field theory which arises from a novel embedding of D-branes in a Melvin universe. We study several rotating and pulsating string solutions of the F-string equations of motion in the supergravity dual ...

Penrose limits and maximal supersymmetry
, 2002 We show that the maximally supersymmetric pp-wave of 1113 superstring and M-theories can be obtained as a Penrose limit of the supersymmetric AdS x S solutions.

Magnetic Heisenberg-chain/pp-wave correspondence
, 2007 We find a decoupling limit of planar ≤ 4 super Yang-Mills (SYM) on × S3 in which it becomes equivalent to the ferromagnetic XXX1/2 Heisenberg spin chain in an external magnetic field. The decoupling limit generalizes the one found in ref.

Open strings in a pp-wave background from defect conformal field theory [PDF]
, 2003 We consider open strings ending on a D5-brane in the pp-wave background, which is realized in the Penrose limit of AdS5×S5 with an AdS4×S2 brane. A complete set of gauge invariant operators in the defect conformal field theory is constructed which is ...
