Recent developments have introduced a groundbreaking form of collinear magnetism
known as “altermagnetism”. This emerging magnetic phase is characterized by robust time …

Nonreciprocal superconductivity, also known as the superconducting diode effect, has been
extensively studied in the presence of a magnetic field or some form of ferromagnetic order …

We introduce a universal methodology for generating and manipulating altermagnetism in
two-dimensional (2D) magnetic Van der Waals (MvdW) materials through twisting. We find …

We study the Josephson effect in the spin-singlet superconductor/altermagnet/spin-triplet
superconductor junctions using the Green's function method. The current-phase difference …

We propose to implement tunable higher-order topological states in a heterojunction
consisting of a two-dimensional (2D) topological insulator and the recently discovered …

Recently, a new kind of collinear magnetism, dubbed altermagnetism, has attracted
considerable interests. A key characteristic of altermagnet is the momentum-dependent …

The discovery of advanced materials is the cornerstone of human technological
development and progress. The structures of materials and their corresponding properties …

The field-free and highly efficient diodes with the nonreciprocity of supercurrent are believed
to be the core block of superconducting computing devices without dissipation. In this paper …

The electronic spectra of altermagnets are a fertile ground for non-trivial topology due to the
unique interplay between time-reversal and crystalline symmetries. This is reflected in the …

We investigate topological phases in a bilayer system composed of an altermagnet and a
two-dimensional topological insulator described by the Bernevig-Hughes-Zhang model. A …
