Closed Strings Tachyons and Non-Commutative Instabilities [PDF]
, 2003 We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non ...

Half-string oscillator approach to string field theory [PDF]
Nuclear Physics B, 1991 Abstract We give an operator formulation of the string field theory proposed by E. Witten using half-string oscillator modes. This formalism, identifying the physical string states as infinite matrices, is developed in such a way that interactions at the level of vertices can be calculated in terms of products and traces of these matrices without ...

On tensionless string field theory in AdS3
Journal of High Energy Physics, 2019 We report on progress in formulating a field theory of tensionless strings in AdS3, starting from the dual large-N symmetric orbifold CFT. We propose a set of field equations which are gauge invariant under the higher spin algebra of the theory, the ...

Dual D-brane actions in nonrelativistic string theory
Journal of High Energy Physics, 2022 We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory.

Unoriented Open-Closed String Field Theory [PDF]
, 1997 The string field theory for unoriented open-closed string mixed system is constructed up to quadratic order based on the joining-splitting type vertices. The gauge invariance with closed string transformation parameter is proved.

Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Background field method for nonlinear sigma models in nonrelativistic string theory
Journal of High Energy Physics, 2020 We continue the study of nonrelativistic string theory in background fields. Nonrelativistic string theory is described by a nonlinear sigma model that maps a relativistic worldsheet to a non-Lorentzian and non-Riemannian target space geometry, which is ...

On String Field Theory and Effective Actions
, 1992 A truncation of string field theory is compared with the duality invariant effective action of $D=4, N=4$ heterotic strings to cubic order. The three string vertex must satisfy a set of compatibility conditions.
