Historically\, the evo lution of our understanding of magnetism has been related to the discovery of new paradigms in condensed-matter physics\, as exemplified by the conn ections between antiferromagnetism and Mott insulators\, spin glasses and non-ergodic states\, and spin liquids and fractionalized excitations. Rece ntly\, a new framework proposed to classify magnetic phases brought renewe d interest in unconventional magnetic states\, which are qualitatively dis tinct from ferromagnets and standard Néel antiferromagnets. Among those\, altermagnetic phases have been met with enthusiasm by the scientific comm unity\, as they display properties found in both ferromagnets (like the sp litting of electronic bands with opposite spins) and conventional antiferr omagnets (like the absence of a net magnetization). Formally\, what distin guishes these three different magnetic states are the crystalline symmetri es that\, when combined with time reversal\, leave the system invariant. I n the case of altermagnets\, because these symmetries involve rotations\, the system is endowed with unique properties such as nodal spin-splitting and piezomagnetism. In this talk\, I will introduce the concept of alterma gnetism and discuss its connection to long-standing problems in the field of quantum materials\, such as multipolar magnetism and electronic liquid- crystalline phases. I will also present the predicted experimental signatu res of altermagnetic order in thermodynamic and transport properties\, and show that altermagnets provide a fertile ground to realize non-trivial to pological and superconducting phenomena in quantum materials.\n\nBio:\n\nP rof.
