Soft theorems in superstring theory [PDF]
Journal of High Energy Physics, 2017 We use insights from superstring field theory to prove the subleading soft graviton theorem for tree amplitudes of (compactified) heterotic and type II string theories for arbitrary number of finite energy NS (NSNS) sector external states but only one ...

A superstring field theory for supergravity [PDF]
Journal of High Energy Physics, 2017 A covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner.

Supersymmetry in open superstring field theory [PDF]
Journal of High Energy Physics, 2017 We realize the 16 unbroken supersymmetries on a BPS D-brane as invariances of the action of the corresponding open superstring field theory. We work in the small Hilbert space approach, where a symmetry of the action translates into a symmetry of the ...

Recent developments in superstring theory [PDF]
Proceedings of the National Academy of Sciences, 1998 There have been many remarkable developments in our understanding of superstring theory in the past few years, a period that has been described as “the second superstring revolution.” In particular, what once appeared to be five distinct theories are now recognized to be different manifestations of a single (unique) underlying theory.

Toward simulating superstring/M-theory on a quantum computer [PDF]
Journal of High Energy Physics, 2021 We present a novel framework for simulating matrix models on a quantum computer. Supersymmetric matrix models have natural applications to superstring/M-theory and gravitational physics, in an appropriate limit of parameters.

Band Tailoring Enabled Perovskite Devices for X‐Ray to Near‐Infrared Photodetection [PDF]
Advanced Science, Volume 12, Issue 9, March 6, 2025.Perovskite‐based photodetectors are improved for wide‐spectrum detection X‐rays to near‐infrared using a type‐II heterojunction with tellurium. This design reduces dark current noise and enhances sensitivity, with a scalable sensor array showing promise for imaging applications.

On the Foundations of Superstring Theory [PDF]
Foundations of Physics, 2013 Superstring theory is an extension of conventional quantum field theory that allows for stringlike and branelike material objects besides pointlike particles. The basic foundations on which the theory is built are amazingly shaky, and, equally amazingly, it seems to be this lack of solid foundations to which the theory owes its strength.

Unitarity of superstring field theory [PDF]
Journal of High Energy Physics, 2016 A bstractWe complete the proof of unitarity of (compactified) heterotic and type II string field theories by showing that in the cut diagrams only physical states appear in the sum over intermediate states.

Open-closed homotopy algebra in superstring field theory [PDF]
arXiv, 2022 We construct open-closed superstring interactions based on the open-closed homotopy algebra structure. It provides a classical open superstring field theory on general closed-superstring-field backgrounds described by classical solutions of the nonlinear equation of motion of the closed superstring field theory.

On finite-size d-branes in superstring theory [PDF]
Journal of High Energy Physics, 2019 We test exact marginality of the deformation describing the blow-up of a zero- size D(−1) brane bound to a background of D3-branes by analyzing the equations of motion of superstring field theory to third order in the size.
