Quasicrystals are metallic alloys that possess long-range, aperiodic structures with diffraction symmetries forbidden to conventional crystals. Since the discovery of quasicrystals by Schechtman et al. in 1984, there has been considerable progress in resolving their geometric structure. For example, it is well known that the golden ratio of mathematics and art occurs over and over again in their crystal structure. However, the characteristic properties of the electronic states--whether they are… 
Conventional superconductivity in quasicrystals
Motivated by a recent experimental observation of superconductivity in the Al-Zn-Mg quasicrystal, we study the low-temperature behavior of electrons moving in the quasiperiodic potential of the
Distributed Hybridization Model for Quantum Critical Behavior in Magnetic Quasicrystals
A quantum critical behavior of the magnetic susceptibility was observed in a quasicrystal containing ytterbium. At the same time, a mixed-valence feature of Yb ions was reported, which appears to be
Quantum diffusion of electrons in quasiperiodic and periodic approximant lattices in the rare earth-cadmium system
Icosahedral quasicrystals are characterised by the absence of a distinct Drude peak in their low-frequency optical conductivity and the same is true of their crystalline approximants. We have
Concomitant singularities of Yb-valence and magnetism at a critical lattice parameter of icosahedral quasicrystals and approximants
TLDR
High-resolution partial-fluorescence-yield x-ray absorption spectroscopy on Yb-based intermediate-valence icosahedral QCs and cubic approximant crystals (ACs) finds that for both forms ofQCs and ACs, there is a critical lattice parameter where Yb -valence and magnetism concomitantly exhibit singularities, suggesting a critical-valences-fluctuation-induced NFL.

Quantum Criticality Without Tuning in the Mixed Valence Compound β-YbAlB4
TLDR
High-precision magnetization measurements of the ultrapure f-electron–based superconductor β-YbAlB4 demonstrate a scaling of its free energy that is indicative of zero-field quantum criticality without tuning in a metal.
Theory of Electronic Structure in Quasicrystals
Shechtman, Blech, Gratias, and Cahn discovered a sharp diffraction pattern of icosahedral (i) symmetry in the Al-Mn alloy rapidly quenched from the melt and reported the i phase of metallic alloys
Atomic structure of the binary icosahedral Yb-Cd quasicrystal.
TLDR
The structure is not only chemically feasible, but also provides a seamless structural understanding of the i-YbCd(5.7) phase and its series of related i-QCs and approximant crystals, revealing hierarchic features that are of considerable physical interest.
Kondo-cluster-glass state near a ferromagnetic quantum phase transition.
TLDR
Despite pronounced non-Fermi-liquid effects in both specific heat and thermal expansion, the Grüneisen ratio does not diverge as T --> 0, providing evidence for the absence of a quantum critical point.
Locally critical quantum phase transitions in strongly correlated metals

TLDR
A 29Si NMR study on aligned single crystals of YbRh2Si2 which shows behavior characteristic of a quantum critical point (QCP: T(N)-->0) strongly suggests the development of antiferromagnetic fluctuations with finite q vectors that compete with q=0 spin fluctuations in the vicinity of the QCP near H=0.5 kOe.

TLDR

Quantum valence criticality as an origin of unconventional critical phenomena.
TLDR
The mode-coupling theory is constructed taking account of local correlation effects of f electrons and finds that unconventional criticality is caused by the locality of the valence fluctuation mode.
