Invited talk

Altermagnetism, a recently established class of magnetic order, combines key features of ferromagnetism and Néel antiferromagnetism, leading to unconventional spin splitting without net magnetization. Building on our previous works [PRB 112, 184501 (2025); PRB 113, 024518 (2026); arXiv:2603.12897] on unconventional superconductivity in single-band treatment, we here investigate the crucial...

Quantum geometry quantifies how the single-particle Bloch wavefunction changes in phase and amplitude across the Brillouin Zone. In multi-orbital systems where bands have strongly mixed orbital composition, quantum geometry plays a vital role in determining the ground state and low-energy properties of interacting electronic systems. In this work, we show that Mott metal-insulator transitions,...

Antiferromagnetic materials constitute an important topic of contemporary condensed matter research and their use encompasses modern spintronics, data storage, etc. Importantly, layered antiferromagnetic copper(II) oxides constitute parent compounds of high-Tc superconductors and superconductivity is achieved via chemical or physical doping to these materials. Oxocuprates(II) feature very...

269. Multiscale complexity of two-dimensional Ising systems with short-range, ferromagnetic interactions

AIP | Condensed Matter & Materials (CMM)

Contributed Oral

Complex systems exhibit macroscopic behaviors that emerge from the coordinated interactions of their individual components. Understanding the microscopic origins of these emergent properties remains a significant challenge, especially in less-understood systems, due to the absence of a generalized framework for identifying the governing degrees of freedom. The multiscale complexity formalism,...

45. Quantum Optical Signatures of Band Topology in Solid-State High Harmonics

We develop a general theory of high-harmonic generation (HHG) in solid-state systems, based on a weak-correlation expansion of photonic and matter degrees of freedom. Unlike standard HHG theories, which treat light-matter dynamics through the Schr¨odinger equation, our approach employs density-matrix evolution, naturally capturing the mixed-state character of both the field and the matter - a...
