Boosting State Discrimination in Quantum Brownian Motion Channel via Memory-Induced Coherence Preservation
João C. P. Porto, Pedro R. Dieguez, Carlos H. S. Vieira +3
Preserving quantum resources in dissipative environments is a fundamental challenge in quantum information processing. While environmental interactions usually degrade quantum reso…
Layer-Resolved Topological Metals in the Bilayer Lieb Lattice
Mengjie Yang, S Rahul, Giandomenico Palumbo
The paper proposes a two‑dimensional time‑reversal‑invariant topological metallic phase on a bilayer Lieb lattice, characterized by a layer‑resolved pseudo‑spin Chern number and fe…
Zero Indirect Band Gap in Non-Hermitian Systems
S Rahul, Giandomenico Palumbo
Zero indirect gaps in band models are typically viewed as unstable and achievable only through fine-tuning. Recent works, however, have revealed robust semimetallic phases in Hermi…
Probing Tensor Monopoles and Gerbe Invariants in Three-Dimensional Topological Matter
Wojciech J. Jankowski, Robert-Jan Slager, Giandomenico Palumbo
We show that momentum-space tensor monopoles corresponding to nontrivial vector bundle generalizations, known as bundle gerbes, can be realized in bands of three-dimensional topolo…
Fractonic self-duality and covariant magnetic fractons
Erica Bertolini, Giandomenico Palumbo
Fractons, excitations with restricted mobility, have emerged as a novel paradigm in high-energy and condensed matter physics, revealing deep connections to gauge theories and gravi…
Geometric Bloch oscillations and transverse displacement in flat band systems
Jing-Xin Liu, Giandomenico Palumbo, Marco Di Liberto
We investigate transport phenomena and dynamical effects in flat bands where the band dispersion plays no role. We show that wavepackets in geometrically non-trivial flat bands can…
