We study the subgap Yu-Shiba-Rusinov (YSR) states in Richardson's model of a superconductor with magnetic impurity for different electron pairing strengths from weak-coupling Bardeen-Cooper-Schrieffer (BCS) regime to strong-coupling Bose-Einstein-condensate (BEC) regime. observe that effect increasing strength on YSR excitation spectrum as function hybridisation and on-site potential is only qu...

When the exchange interaction between impurity spin and spins of itinerant quasiparticles are strong or weak enough, ground states for a magnetic in superconductor screened free spins, respectively. In both cases, lowest excited state is bound within superconducting gap, known as Yu-Shiba-Rusinov (YSR) state. The YSR spatially localized, energetically isolated, fully spin-polarized, leading to ...

It has been predicted theoretically and found experimentally that magnetic impurities induce localized bound states within the superconducting energy gap, called Yu-Shiba-Rusinov (YSR) states. Combining symmetry analysis with experimental findings provides a convincing argument for splitting distribution of YSR peaks, but full details electronic structure remain elusive simple models point scat...

Very recent experiments have reported the tunneling between Yu-Shiba-Rusinov (YSR) bound states at atomic scale. These been realized with help of a scanning microscope where superconducting tip is functionalized magnetic impurity and used to probe another deposited on substrate. In this way it has become possible study for first time spin-dependent transport individual states. Motivated by thes...

Abstract Local quasiparticle states around impurities provide essential insight into the mechanism of unconventional superconductivity, especially when candidate materials are proximate to an antiferromagnetic Mott-insulating phase. While such have been reported in atom-based cuprates and iron-based compounds, they unexplored organic superconductors which feature tunable molecular orientation. ...

Theoretical descriptions of Yu-Shiba-Rusinov (YSR) states induced by magnetic impurities inside the gap a superconductor typically rely on classical spin model or are restricted to spin-1/2 quantum spins. These models fail account for important aspects YSR transition-metal impurities, including effects higher spins coupled several conduction-electron channels, crystal ligand-field effects, and ...

Magnetic impurities in $s$-wave superconductors lead to spin-polarized Yu-Shiba-Rusinov (YSR) in-gap states. Chains of magnetic offer one the most viable routes for realization Majorana bound states which hold a promise topological quantum computing. However, this ambitious goal looks distant since no coherent degrees freedom have yet been identified these systems. To fill gap we propose an eff...

OBJECTIVE The aim of this study was to examine the prevalence of Internet addiction in middle school students and to identify associated psychosocial risk factors and depression. METHODS This study was part of a larger epidemiological study on childhood psychiatric disorders conducted in Osan, a city of Republic of Korea. We used IAS for internet addiction, K-YSR for subjects' emotional and b...

Validated brief screening instruments are needed to improve the detection of anxiety disorders in autism spectrum disorder (ASD). The Screen for Child Anxiety-Related Emotional Disorders (SCARED), a 41-item parent- and self-reported scale measuring anxiety, was compared to the Achenbach System of Empirically Based Assessment (ASEBA) scales. One hundred participants with a clinical diagnosis of ...
