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

This Colloquium reviews the 25 year quest to understand the continuous (second-order),
mean-field-like phase transition occurring at 17.5 K in URu 2 Si 2. About ten years ago, the …

Spin-triplet superconductors are of extensive current interest because they can host
topological state and Majorana fermions important for quantum computation. The uranium …

Complex electronic matter shows subtle forms of self-organization, which are almost
invisible to the available experimental tools. One prominent example is provided by the …

The development of collective long-range order by means of phase transitions occurs by the
spontaneous breaking of fundamental symmetries. Magnetism is a consequence of broken …

The multipole concept, which characterizes the spacial distribution of scalar and vector
objects by their angular dependence, has already become widely used in various areas of …

We report a comprehensive electronic structure investigation of the paramagnetic (PM), the
large moment antiferromagnetic (LMAF), and the hidden order (HO) phases of URu 2 Si 2 …

A broken symmetry ground state without any magnetic moments has been calculated by
means of the local-density approximation to density functional theory plus a local exchange …

Spontaneous symmetry breaking in physical systems leads to salient phenomena at all
scales, from the Higgs mechanism and the emergence of the mass of the elementary …

Using Shubnikov–de Haas oscillations measured in URu 2 Si 2 over a broad range in a
magnetic field of 11–45 T, we find a cascade of field-induced Fermi surface changes within …
