Incommensurate grain-boundary atomic structure [PDF]

Nature Communications, 2023
Grain-boundary atomic structures of crystalline materials have long been believed to be commensurate with the crystal periodicity of the adjacent crystals.

Dark sector effective field theory

Journal of High Energy Physics, 2023
We introduce the effective field theory of two different light dark particles interacting with the standard model (SM) light states in a single vertex, termed dark sector effective field theory (DSEFT). We focus on the new light particles with spin up to

Quasinormal modes and stability of higher dimensional rotating black holes under massive scalar perturbations

Physics Letters B, 2023
We consider the stability of six-dimensional singly rotating Myers-Perry black holes under massive scalar perturbations. Using Leaver's continued fraction method, we compute the quasinormal modes of the massive scalar fields.

Study of the particle transverse momentum spectra in relativistic heavy ion collisions using the Tsallis statistics

EPJ Web of Conferences, 2014
In this work, we have analized the transverse momentum spectra of charged pions produced in Au+Au collisions at different energies using the non-extensive Tsallis distribution.

Study of the multiplicity distributions in relativistic nucleus - nucleus collisions using the multiplicity distribution moments method

EPJ Web of Conferences, 2014
In this work, we will present beam energy and system size dependence of the higher order moments (skewness and kurtosis) of net-kaon and total proton multiplicity distributions for Au+Au collisions simulated using the UrQMD code.

Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters

Nature Communications, 2021
Dimensionality reduction can occur in magnetically frustrated systems; however, it typically involves lattice distortions. Here, the authors report two- and one-dimensional character of spin correlations in a three-dimensional tetrahedral cluster ...

An Oligopeptide-Protected Ultrasmall Gold Nanocluster with Peroxidase-Mimicking and Cellular-Imaging Capacities

Molecules, 2022
Recent decades have witnessed the rapid progress of nanozymes and their high promising applications in catalysis and bioclinics. However, the comprehensive synthetic procedures and harsh synthetic conditions represent significant challenges for nanozymes.

“Z”‐Type Tilted Quasi‐One‐Dimensional Assembly of Actinide‐Embedded Coinage Metal Near‐Plane Superatoms and Their Optical Properties

Advanced Science, 2023
In this work, a novel discovery that the coinage‐metal near‐plane superatoms (CM‐NPSs) formed by embedding actinide elements into the coinage metal rings can realize the “Z”‐type tilted quasi‐one‐dimensional (1D) direct assembly is reported. This success

Deep learning approach for an interface structure analysis with a large statistical noise in neutron reflectometry

Scientific Reports, 2021
Neutron reflectometry (NR) allows us to probe into the structure of the surfaces and interfaces of various materials such as soft matters and magnetic thin films with a contrast mechanism dependent on isotopic and magnetic states.

Observation of a shape resonance of the positronium negative ion

Nature Communications, 2016
The Positronium negative ion is formed by two electrons bound to a positron, and experimental investigations of its states and energy levels are difficult due to its short lifetime.
