Nodeless superconductivity in IrPtTe with strong spin-orbital coupling
The thermal conductivity of superconductor IrPtTe
( = 0.05) single crystal with strong spin-orbital coupling was measured down
to 50 mK. The residual linear term is negligible in zero magnetic
field. In low magnetic field, shows a slow field dependence. These
results demonstrate that the superconducting gap of IrPtTe is
nodeless, and the pairing symmetry is likely conventional s-wave, despite the
existence of strong spin-orbital coupling and a quantum critical point.Comment: 5 pages, 4 figure
Work Function of Single-wall Silicon Carbide Nanotube
Using first-principles calculations, we study the work function of single
wall silicon carbide nanotube (SiCNT). The work function is found to be highly
dependent on the tube chirality and diameter. It increases with decreasing the
tube diameter. The work function of zigzag SiCNT is always larger than that of
armchair SiCNT. We reveal that the difference between the work function of
zigzag and armchair SiCNT comes from their different intrinsic electronic
structures, for which the singly degenerate energy band above the Fermi level
of zigzag SiCNT is specifically responsible. Our finding offers potential
usages of SiCNT in field-emission devices.Comment: 3 pages, 3 figure
Experimental studies of the interaction between people and virtual humans with a focus on social anxiety
Psychotherapy has been one of the major applications of Virtual Reality technology; examples include fear of flying, heights, spiders, and post‐traumatic
stress disorder. Virtual reality has been shown to be useful, in the context of exposure therapy for the treatment of social anxiety, such as fear of public speaking, where the clients learn how to conquer their anxiety through interactions with Virtual Characters (avatars).
This thesis is concerned with the interaction between human participants and avatars in a Virtual Environment (VE), with the main focus being on Social Anxiety. It is our hypothesis that interactions between people and avatars can evoke in people behaviours that correspond to their degree of social anxiety or confidence.
Moreover the responses of people to avatars will also depend on their degree of exhibited social anxiety – they will react differently to a shy avatar compared to a
confident avatar.
The research started with an experimental study on the reaction of shy and confident male volunteers to an approach by an attractive and friendly virtual woman in a VE. The results show that the participants responded according to expectations towards the avatar at an emotional, physiological, and behavioural level. The research then studied a particular cue which represents shyness – “blushing”. Experiments were carried out on how participant responds towards a blushing avatar. The results suggested that, even without consciously noticing the
avatar’s blushing, the participants had an improved relationship with her when she was blushing. Finally, the research further investigated how people respond towards
a shy avatar as opposed to a confident one. The results show that participants gave more positive comments to the personality of the avatar displaying signs of shyness
Spaces of low-degree rational curves on Fano complete intersections
In this paper, we prove that the moduli space of low degree rational curves on a lowdegree complete intersection passing several suitable points is a complete intersection. The proof involves some relationships among some divisors on the Kontsevich spaces, advanced techniques of deformations of rational curves, and classical projective geometry
