Diagonal Isometric Form for Tensor Network States in Two Dimensions
Benjamin Sappler, Masataka Kawano, Michael P Zaletel +1
Isometric tensor network states (isoTNS) generalize the isometric form of the one-dimensional matrix product states (MPS) to tensor networks in two and higher dimensions. Here, we…
Dynamical magnetic breakdown and quantum oscillations from hot spot scattering
Léo Mangeolle, Johannes Knolle
Quantum oscillations (QO) are a well-established probe of Fermi-surface (FS) geometry and in the presence of long-range density wave order can display new QO frequencies from recon…
Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…
Spontaneously Broken Non-Invertible Symmetries in Transverse-Field Ising Qudit Chains
Kristian Tyn Kai Chung, Umberto Borla, Andriy H. Nevidomskyy +1
Recent developments have revealed that symmetries need not form a group, but instead can be non-invertible. Here we use analytical arguments and numerical evidence to illuminate ho…
Theory of Angle Resolved Photoemission Spectroscopy of Altermagnetic Mott Insulators
Lorenzo Lanzini, Purnendu Das, Michael Knap
Altermagnetism has emerged as an unconventional form of collinear magnetism with spatial rotational symmetries, that give rise to strongly spin-split bands despite of an underlying…
Purely electronic model for exciton-polaron formation in moiré heterostructures
Fabian Pichler, Mohammad Hafezi, Michael Knap
Understanding interactions between excitons and correlated electronic states presents a fundamental challenge in quantum many-body physics. Here, we introduce a purely electronic m…
