Singular Value Decomposition and Its Blind Spot for Quantum Chaos in Non-Hermitian Sachdev-Ye-Kitaev Models
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +3
The study of chaos and complexity in non-Hermitian quantum systems poses significant challenges due to the emergence of complex eigenvalues in their spectra. Recently, the singular…
Atomistic mechanisms of dynamics in a two-dimensional dodecagonal quasicrystal
Kun Zhao, Matteo Baggioli, Wen-Sheng Xu +2
Quasicrystals have been observed in a variety of materials ranging from metal alloys to block copolymers. However, their structural and dynamical properties cannot be readily descr…
Chiral Anomalous Magnetohydrodynamics in action: effective field theory and holography
Matteo Baggioli, Yanyan Bu, Xiyang Sun
Chiral Anomalous Magnetohydrodynamics (CAMHD) provides a low-energy effective framework for describing chiral fluids in the presence of dynamical electromagnetic fields and axial a…
Hedgehog topological defects in 3D amorphous solids
Arabinda Bera, Alessio Zaccone, Matteo Baggioli
The underlying structural disorder renders the concept of topological defects in amorphous solids difficult to apply and hinders a first-principle identification of the microscopic…
Revisiting the question of what instantaneous normal modes tell us about liquid dynamics
Sha Jin, Xue Fan, Matteo Baggioli
The lack of a well-defined equilibrium reference configuration has long hindered a comprehensive atomic-level understanding of liquid dynamics and properties. The Instantaneous Nor…
Revisiting the phonon theory of liquid heat capacity: low-frequency shear modes and intramolecular vibrations
Yu Liu, Matteo Baggioli
Modeling the heat capacity of liquids present fundamental difficulties due to the strong intermolecular particle interactions and large diffusive-like displacements. Based on the e…
