Ultra-stable charging of fast-scrambling SYK quantum batteries
Dario Rosa, Davide Rossini, Gian Marcello Andolina +2
Collective behavior strongly influences the charging dynamics of quantum batteries (QBs). Here, we study the impact of nonlocal correlations on the energy stored in a system of …
Quantum advantage in the charging process of Sachdev-Ye-Kitaev batteries
Davide Rossini, Gian Marcello Andolina, Dario Rosa +2
The exactly-solvable Sachdev-Ye-Kitaev (SYK) model has recently received considerable attention in both condensed matter and high energy physics because it describes quantum matter…
Control of electron-electron interaction in graphene by proximity screening
M. Kim, S. G. Xu, A. I. Berdyugin +14
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One…
Phonon-mediated superconductivity in strongly correlated electron systems: a Luttinger-Ward functional approach
Andrea Secchi, Marco Polini, Mikhail I. Katsnelson
We use a Luttinger-Ward functional approach to study the problem of phonon-mediated superconductivity in electron systems with strong electron-electron interactions (EEIs). Our der…
Collective excitations in twisted bilayer graphene close to the magic angle
Niels C. H. Hesp, Iacopo Torre, Daniel Rodan-Legrain +14
The electronic properties of twisted bilayer graphene (TBG) can be dramatically different from those of a single graphene layer, in particular when the two layers are rotated relat…
Viscous electron fluids
Marco Polini, Andre K Geim
Recent advances in materials science have made it possible to achieve conditions under which electrons in metals start behaving as highly viscous fluids, "thicker than honey", and…
