Line operators of gauge theories on non-spin manifolds

open access: yesJournal of High Energy Physics, 2020
We study four-dimensional gauge theories on oriented and non-spin spacetime manifolds. On such manifolds, each line operator arises only either as a boson or a fermion. Based on physical arguments, a method of systematically assigning spin labels to line

Electron paramagnetic resonance (EPR) spectral components of spin-labeled lipids in saturated phospholipid bilayers: effect of cholesterol

open access: yesQuímica Nova, 2013
Electron paramagnetic resonance (EPR) spectroscopy was used to study the main structural accommodations of spin labels in bilayers of saturated phosphatidylcholines with acyl chain lengths ranging from 16 to 22 carbon atoms.

Incorporation of Spin Labels and Paramagnetic Tags for Magnetic Resonance Studies Using Cycloaddition Reactions as a Tool

open access: yesReactions
The cycloaddition reaction is one of the most common reactions in organic chemistry. It has been applied in various fields. Herein, we focus on the application of cycloaddition reactions in investigating biological molecules and materials using magnetic ...

The integrable quantum group invariant A2n−1(2) and Dn+1(2) open spin chains

open access: yesNuclear Physics B, 2017
A family of A2n(2) integrable open spin chains with Uq(Cn) symmetry was recently identified in arXiv:1702.01482. We identify here in a similar way a family of A2n−1(2) integrable open spin chains with Uq(Dn) symmetry, and two families of Dn+1(2 ...

Spin Foam Vertex Amplitudes on Quantum Computer—Preliminary Results

open access: yesUniverse, 2019
Vertex amplitudes are elementary contributions to the transition amplitudes in the spin foam models of quantum gravity. The purpose of this article is to make the first step towards computing vertex amplitudes with the use of quantum algorithms.
