Casimir Energy of a Long Wormhole Throat [PDF]
Phys. Rev. D 90, 024019 (2014), 2014 We calculate the Casimir energy-momentum tensor induced in a scalar field by a macroscopic ultrastatic spherically-symmetric long-throated traversable wormhole, and examine whether this exotic matter is sufficient to stabilise the wormhole itself. The Casimir energy-momentum tensor is obtained (within the $\mathbb{R}\times S_2$ throat) by a mode sum ...

Advanced Materials, EarlyView.Omnidirectional strain sensing is crucial in healthcare monitoring, human motion detection, and human‐machine interfaces. By mimicking the 3D structure of human fingers, this work introduces a novel heterogeneous substrate incorporating the involute of a circle which enables the device to achieve isotropic omnidirectional hypersensitive strain sensing ...

IR Dynamics of d=2, N=(4,4) Gauge Theories and DLCQ of "Little String Theories" [PDF]
JHEP 9910:030,1999, 1999 We analyze the superconformal theories (SCFTs) which arise in the low-energy limit of N=(4,4) supersymmetric gauge theories in two dimensions, primarily the Higgs branch SCFT. By a direct field theory analysis we find a continuum of "throat"-like states localized near the singularities of the Higgs branch.

Advanced Materials Interfaces, EarlyView.This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...

arXiv, 2010 In this thesis, we study throats in the early, hot universe. Throats are a common feature of the landscape of type IIB string theory. If a throat is heated during cosmological evolution, energy is subsequently transferred to other throats and to the standard model.

Interfacial Yield Stress Response in Synthetic Mucin Solutions
Advanced Materials Interfaces, EarlyView.The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

Advanced Materials Technologies, EarlyView.A stretchable and bendable resistance sensor made predominantly from sustainable and biodegradable components is conductive courtesy a water soluble self‐doped conjugated polymer. The wearable sensor measures micromovements by changes in its resistance and it can track both human movement and phonation. Abstract Sustainable electronic devices offer the
