Emergent fracton strings from covariant bi-form gauge field theory
Erica Bertolini, Hyungrok Kim, Giandomenico Palumbo
We present a covariant field-theoretical framework for a rank-4 tensor gauge field theory describing fractonic string-like objects. We show that the most general quadratic, parity-…
Probing Tensor Singularities and Their Euler-Class Descendants via Non-Abelian Quantum Geometry Measurement
Zhe Wang, Yan-Qing Zhu, Xinsheng Tan +5
We report the theoretical prediction and experimental observation of a new class of four-dimensional (4D) tensor singularities and their three-dimensional (3D) Euler-class descenda…
Generalized GMP Algebra for Three-Dimensional Quantum Hall Fluids of Extended Objects
Giandomenico Palumbo
We develop a geometric framework for three-dimensional quantum Hall fluids of extended objects (quasi-strings) in the presence of a strong three-form background field associated wi…
Quantum geometric tensors from sub-bundle geometry
Marius A. Oancea, Thomas B. Mieling, Giandomenico Palumbo
The geometric properties of quantum states are crucial for understanding many physical phenomena in quantum mechanics, condensed matter physics, and optics. The central object desc…
Weyl Geometry in Weyl Semimetals
Giandomenico Palumbo
A novel oscillatory behaviour of the DC conductivity in Weyl semimetals with vacancies has recently been identified, occurring in the absence of external magnetic fields. Here, we…
