Strongly frustrated magnetism of the metallic pyrochlore oxide Pr 2 Ir 2 O 7 has been
revealed by single crystal study. While Pr 4 f moments have an antiferromagnetic RKKY …

The strange metal phase of correlated electrons materials was described in a recent theory
by a model of a Fermi surface coupled a two-dimensional quantum critical bosonic field with …

We study a controlled large-N theory of electrons coupled to dynamical two-level systems
(TLSs) via spatially random interactions. Such a physical situation arises when electrons …

Solid-state physics and soft-matter physics have been developed independently, with little
mutual exchange of the underlying physical concepts. However, after many studies of …

Motivated by the intrinsic non-Fermi-liquid behavior observed in the heavy-fermion
quasicrystal Au 51 Al 34 Yb 15, we study the low-temperature behavior of dilute magnetic …

We extend the numerical renormalization-group method to treat Bose-Fermi Kondo models
(BFKMs) describing a local moment coupled both to a conduction band and to a dissipative …

We present a detailed study of the physical properties of single crystalline UPt 2 Si 2. By
neutron diffraction we establish the presence of frozen-in strain disorder on the Pt (2)/Si (2) …

The Mott and the Anderson routes to localization have long been recognized as the two
basic processes that can drive the metal–insulator transition (MIT). Theories separately …

Using the functional-integral method, we investigate the effect of a two-level systems thermal
reservoir on the single particle dynamics. We find that at low temperatures, within the sub …

An x-ray spectroscopy study was performed for YbCu 5-x Al x (x= 0.0–2.0) using high-
resolution partial-fluorescence yield (PFY) and resonant inelastic x-ray scattering (RIXS) at …
