Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Near-extremal Kerr-like ECO in the Kerr/CFT correspondence in higher spin perturbations

open access: yesEuropean Physical Journal C: Particles and Fields
The Kerr/CFT correspondence has been established to explore the quantum theory of gravity in the near-horizon geometry of an extreme Kerr black holes. The quantum gravitational corrections on the near-horizon region may manifest in form of a partially ...

Anisotropic Turbulent Advection of a Passive Vector Field: Effects of the Finite Correlation Time

open access: yesEPJ Web of Conferences, 2016
The turbulent passive advection under the environment (velocity) field with finite correlation time is studied. Inertial-range asymptotic behavior of a vector (e.g., magnetic) field, passively advected by a strongly anisotropic turbulent flow, is ...

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Seesaw mirroring between light and heavy Majorana neutrinos with the help of the S 3 reflection symmetry

open access: yesJournal of High Energy Physics, 2019
In the canonical seesaw mechanism we require the relevant neutrino mass terms to be invariant under the S 3 charge-conjugation transformations of left- and right-handed neutrino fields.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Holographic Multiquarks in the Quark-Gluon Plasma: A Review

open access: yesAdvances in High Energy Physics, 2011
We review the holographic multiquark states in the deconfined quark-gluon plasma. Nuclear matter can become deconfined by extremely high temperature and/or density. In the deconfined nuclear medium, bound states with colour degrees of freedom are allowed

Cross section line shape of e+e−→χc0ω around the Y(4260) mass region

open access: yesPhysics Letters B, 2017
We demonstrate that the recent measurement of the cross section line shapes of e+e−→χc0ω can be naturally explained by the molecular picture for Y(4260) where the Y(4260) is treated as a hadronic molecule dominated by D¯D1(2420)+c.c.

Exploring the CPT violation and birefringence of gravitational waves with ground- and space-based gravitational-wave interferometers

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the gravitational sector, we study the CPT violation and birefringence in gravitational waves. In presence of the CPT violation, a relative dephasing is generated between two circular polarization states of gravitational waves. This effect induces the
