Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

The crossover from weak-coupling Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-
Einstein condensate (BEC) of tightly bound pairs, as a function of the attractive interaction in …

The Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state is a novel superconducting state in a
strong magnetic field characterized by the formation of Cooper pairs with nonzero total …

This topical review summarizes various features of magnetic penetration depth in
unconventional superconductors. Precise measurements of the penetration depth as a …

We present a systematic study of quantum phases in a one-dimensional spin-polarized
Fermi gas. Three comparative theoretical methods are used to explore the phase diagram at …

We report the phase diagram of λ-(BETS) 2 GaCl 4 [where BETS is bis (ethylene-dithio)
tetraselenafulvalene] from rf penetration depth measurements with a tunnel diode oscillator …

The realization of new classes of ground states in strongly correlated electron systems
continues to be a major issue in condensed matter physics. Heavy fermion materials, whose …

We report the first magnetocaloric and calorimetric observations of a magnetic-field-induced
phase transition within a superconducting state to the long-sought exotic Fulde-Ferrell …

We present upper critical field data for κ-(BEDT-TTF) 2 Cu (NCS) 2 with the magnetic field
close to parallel and parallel to the conducting layers. We show that we can eliminate the …

Using quasiclassical theory, we analyze the vortex structure of strong-paramagnetic
superconductors. There, induced paramagnetic moments are accumulated exclusively …
