Universally-Charging Protocols for Quantum Batteries: A No-Go Theorem Open
The effectiveness of a quantum battery relies on a robust charging process, yet these are often sensitive to initial state of the battery. We introduce the concept of a universally-charging (UC) protocol, defined as one that either increas…

Operator-based quantum thermodynamic uncertainty relations Open
The Heisenberg uncertainty relation, which links the uncertainties of the position and momentum of a particle, has an important footprint on the quantum behavior of a physical system. Motivated by this principle, we propose that thermodyna…

Universal localization-delocalization transition in chiral-symmetric Floquet drives Open
Periodically driven systems often exhibit behavior distinct from static systems. In single-particle, static systems, any amount of disorder generically localizes all eigenstates in one dimension. In contrast, we show that in topologically …

Topological Triviality of Flat Hamiltonians Open
Landau levels play a key role in theoretical models of the quantum Hall effect. Each Landau level is degenerate, flat and topologically non-trivial. Motivated by Landau levels, we study tight-binding Hamiltonians whose energy levels are al…

Compact Wannier Functions in One Dimension Open
Wannier functions have widespread utility in condensed matter physics and beyond. Topological physics, on the other hand, has largely involved the related notion of compactly-supported Wannier-type functions, which arise naturally in flat …

Compactly supported Wannier functions and strictly local projectors Open
Wannier functions that are maximally localized help in understanding many\nproperties of crystalline materials. In the absence of topological\nobstructions, they are at least exponentially localized. In some cases such as\nflat-band Hamilt…
