Machine Learning for Green Solvents: Assessment, Selection and Substitution

open access: yesAdvanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,

Topological amplitude computations using the pure spinor formalism

open access: yesJournal of High Energy Physics, 2019
After constructing a simplified four-dimensional version of the b ghost, topological multiloop amplitudes in type II superstring theory compactified on a six-dimensional orbifold are computed using the non-minimal pure spinor formalism. These pure spinor

Defects in the 3-dimensional toric code model form a braided fusion 2-category

open access: yesJournal of High Energy Physics, 2020
It was well known that there are e-particles and m-strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ2 topological order.

TOPOLOGICAL CONSERVATION CURRENT OF COSMIC STRINGS

open access: yes, 2011
In our previous research, we have constructed a second rank antisymmetric topological current to study various topological properties of cosmic strings in the early universe. In this paper, starting from the conservation equation of the current, we give

ML Workflows for Screening Degradation‐Relevant Properties of Forever Chemicals

open access: yesAdvanced Science, EarlyView.
The environmental persistence of per‐ and polyfluoroalkyl substances (PFAS) necessitates efficient remediation strategies. This study presents physics‐informed machine learning workflows that accurately predict critical degradation properties, including bond dissociation energies and polarizability.

Selection rules of topological solitons from non-invertible symmetries in axion electrodynamics

open access: yesJournal of High Energy Physics
We investigate a relation between non-invertible symmetries and selection rules of topological solitons such as axionic domain walls and magnetic strings in the (3 + 1)-dimensional axion electrodynamics with a massive axion or a massive photon.

Quantum mirror curve of periodic chain geometry

open access: yesJournal of High Energy Physics, 2019
The mirror curves enable us to study B-model topological strings on noncompact toric Calabi-Yau threefolds. One of the method to obtain the mirror curves is to calculate the partition function of the topological string with a single brane. In this paper,

The topological renormalisation of the 0(3) sigma model [PDF]

open access: yes, 1995
Like other field theories of physical interest, the moduli-space integrals of the non-linear two-dimensional 0(3) sigma model diverge. We show that in the one-instanton sector the imposition of a cut-off in the moduli-space leads to an unacceptable ...

Topological Strings and Integrable Hierarchies

open access: yes, 2019
We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encode the symmetries of holomorphic diffeomorphisms of the Calabi-Yau. In the highly effective fermionic/

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

open access: yesAdvanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.
