Probing non-Hermitian phase transitions in curved space via quench dynamics
Ygor Pará, Giandomenico Palumbo, Tommaso Macrì
Non-Hermitian Hamiltonians are relevant to describe the features of a broad class of physical phenomena, ranging from photonics and atomic and molecular systems to nuclear physics…
A synthetic monopole source of Kalb-Ramond field in diamond
Mo Chen, Changhao Li, Giandomenico Palumbo +3
Magnetic monopoles play a central role in various areas of fundamental physics, ranging from electromagnetism to topological states of matter. While their observation is elusive in…
Fermionic dualities with axial gauge fields
Adolfo G. Grushin, Giandomenico Palumbo
The dualities that map hard-to-solve, interacting theories to free, non-interacting ones often trigger a deeper understanding of the systems to which they apply. However, simplifyi…
Non-Abelian Bloch oscillations in higher-order topological insulators
Marco Di Liberto, Nathan Goldman, Giandomenico Palumbo
Bloch oscillations (BOs) are a fundamental phenomenon by which a wave packet undergoes a periodic motion in a lattice when subjected to an external force. Observed in a wide range…
Effective field theories for interacting boundaries of 3D topological crystalline insulators through bosonisation
Patricio Salgado-Rebolledo, Giandomenico Palumbo, Jiannis K. Pachos
Here, we analyse two Dirac fermion species in two spatial dimensions in the presence of general quartic contact interactions. By employing functional bosonisation techniques, we de…
Four-dimensional semimetals with tensor monopoles: From surface states to topological responses
Yan-Qing Zhu, Nathan Goldman, Giandomenico Palumbo
Quantum anomalies offer a useful guide for the exploration of transport phenomena in topological semimetals. In this work, we introduce a model describing a semimetal in four spati…
