Bootstrapping ground state properties of classical frustrated magnets
Nisarga Paul, Gil Refael
We introduce a method based on semidefinite programming that produces rigorous two-sided bounds on ground state energy densities and correlation functions of translation-invariant…
Resonant Zener Interferometry in van der Waals Heterostructures
Nisarga Paul, Gil Refael
We demonstrate the presence of quantum interference effects in van der Waals heterostructures subject to in-plane electric fields. The in-plane field accelerates carriers throu…
Superextensive charging speeds in a correlated quantum charger
Harald Schmid, Felix von Oppen, Gil Refael +1
We define a quantum charger as an interacting quantum system that transfers energy between two drives. The key figure of merit characterizing a charger is its charging power. Remar…
Enhanced coherence in the periodically driven two-dimensional XY model
Duilio De Santis, Marios H. Michael, Sambuddha Chattopadhyay +4
Strong optical drives have been shown to induce transient superconducting-like response in materials above their equilibrium . Many of these materials already exhibit short-ra…
Multi-band fractional Thouless pumps
Marius Jürgensen, Jacob Steiner, Gil Refael +1
Quantization of particle transport lies at the heart of topological physics. In Thouless pumps - dimensionally reduced versions of the integer quantum Hall effect - quantization is…
