The most well-known example of an ordered quantum state—superconductivity—is caused
by the formation and condensation of pairs of electrons. Fundamentally, what distinguishes …

Most superconductors have an isotropic, single component order parameter and are well
described by the standard (BCS) theory for superconductivity. Unconventional, multiple …

We show that unconventional nematic superconductors with multicomponent order
parameter in lattices with three-and sixfold rotational symmetries support a charge-4 e …

The effects of fluctuations and disorder, which are substantially enhanced in reduced
dimensionalities, can play a crucial role in producing non-trivial phases of matter such as …

A key question regarding the unconventional superconductivity of S r 2 R u O 4 remains
whether the order parameter is single-or two-component. Under a hypothesis of two …

Charge-4 e superconductivity as a novel phase of matter remains elusive so far. Here, we
show that charge-4e phase can arise as a vestigial order above the nematic …

Despite being of fundamental importance and potential interest for topological quantum
computing, spin-triplet superconductors remain rare in solid state materials after decades of …

The crystallographic restriction theorem constrains two-dimensional nematicity to display
either Ising (Z 2) or three-state-Potts (Z 3) critical behaviors, both of which are dominated by …

It has been shown that many seemingly contradictory experimental findings concerning the
superconducting state in Sr 2 RuO 4 can be accounted for as resulting from the existence of …

We present measurements of the magnetic torque, specific heat and thermal expansion of
the bulk transition metal dichalcogenide (TMD) superconductor NbS2 in high magnetic …
