We formulate a Landau theory for altermagnets, a class of collinear compensated magnets
with spin-split bands. Starting from the nonrelativistic limit, this Landau theory goes beyond a …

Supercurrent flow can induce a nonvanishing spin magnetization in noncentrosymmetric
superconductors with spin-orbit interaction. Often known as the nondissipative …

Metallic altermagnets are unusual collinear magnets that feature zero net magnetization with
momentum-dependent spin splitting. Here, we show that this spin splitting can induce pair …

We theoretically investigate superconductivity under a spin-split band structure owing to a
collinear-type antiferromagnetic order in quasi-two-dimensional organic compounds κ …

Two-dimensional valleys and magnetism are rising areas with intriguing properties and
practical uses in advanced information technology. By coupling valleys to collinear …

We employ a systematic approach to construct superconducting order parameters based on
the spin space group. Compared to magnetic space groups where spatial and spin rotation …

We report our numerical studies on the emergence of a double-Q checkerboard bubble
crystal in centrosymmetric tetragonal magnets. The double-Q checkerboard bubble crystal is …

Unconventional magnetic orders usually interplay with superconductivity in intriguing ways.
In this work, we propose that a conventional superconductor in proximity to a compensated …

We theoretically study the finite-momentum superconductivity in two-dimensional (2D)
altermagnets with a Rashba-type spin-orbit coupling (RSOC). We show the phase diagrams …

topological semimetals host helicoid-arc surface states originating from time-reversal …
