Over the past 35 years, research on unconventional superconductivity in heavy-fermion
systems has evolved from the surprising observations of unprecedented superconducting …

Electron spin resonance-scanning tunneling microscopy (ESR-STM) is a rapidly developing
surface-science technique that is sensitive to a single spin existing on or nearby a solid …

Ce115 and related Ce compounds are particularly suited to detailed studies of the interplay
of antiferromagnetic order, unconventional superconductivity and quantum criticality due to …

Electronic, magnetic, and structural phase inhomogeneities are ubiquitous in strongly
correlated quantum materials. The characteristic length scales of the phase inhomogeneities …

In four classes of materials—the layered copper oxides, organics, iron pnictides and heavy-
fermion compounds—an unconventional superconducting state emerges as a magnetic …

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 …

Emergent inhomogeneous electronic phases in metallic quantum systems are crucial for
understanding high‐Tc superconductivity and other novel quantum states. In particular, spin …

Replacing a magnetic atom by a spinless atom in a heavy-fermion compound generates a
quantum state often referred to as a “Kondo-hole”. No experimental imaging has been …

The Holstein Hamiltonian describes itinerant electrons whose site density couples to local
phonon degrees of freedom. In the single-site limit, at half filling, the electron-phonon …

We present specific heat measurements on a series of BaFe 2 (As 1-x P x) 2 single crystals
with phosphorous doping ranging from x= 0.3 to x= 0.55. Our results reveal that BaFe 2 (As 1 …
