Recent progresses using state-of-the-art experimental techniques have motivated a number
of new insights on heavy fermion physics. This article gives a brief summary of the author's …

Metallic spin liquid has been reported in several correlated metals, but a satisfactory
theoretical description is not yet available. Here we propose a potential route to realize the …

Motivated by the recent discovery of a continuous ferromagnetic quantum phase transition in
CeRh6Ge4 and its distinction from other U-based heavy fermion metals such as UGe2, we …

Heavy-fermion superconductors exhibit unusual properties such as low transition
temperatures, large specific heat jumps, and normal states with universal two-fluid …

Despite many efforts, we still lack a clear picture of how heavy electrons emerge and
develop on the Kondo lattice. Here we introduce a key concept named the hybridization …

Understanding the nature of local–itinerant transition of strongly correlated electrons is one
of the central problems in condensed matter physics. Heavy fermion systems describe the f …

We apply the recently developed slave fermion approach to study the doped Mott insulator
in the one-band Hubbard and Hubbard-Heisenberg models. Our results produce several …

The Mott transition plays a key role in strongly correlated physics, but its nature is not yet
fully understood. Motivated by the recent development of the Schwinger boson approach for …

Millimeter-sized Ce 2 Rh 3+ δ Sb 4 (δ≈ 1/8) single crystals were synthesized by a Bi-flux
method, and their physical properties were studied by a combination of electrical transport …

Neste trabalho, investigou-se os efeitos do campo elétrico cristalino nos compostos
isoestruturais de ErM4Al8 (M= Cu e Fe). As amostras foram produzidas por fusao fornoa …
