OptiQU: Coordinated Multi-Level Voltage and Reactive Power Control for Enhanced Voltage Quality and Secure Grid Operation
Irene Hammermeister, Eric Tönges, Nils Bornhorst +20
Modern low-voltage (LV) distribution grids face rising shares of photovoltaic generation and high-power loads such as heat pumps and electric vehicle charging stations. Due to high…
Topological gravity for arbitrary Dyson index
Torsten Weber, Marco Lents, Johannes Dieplinger +2
We use the well established duality of topological gravity to a double scaled matrix model with the Airy spectral curve to define what we refer to as topological gravity with arbit…
Itinerant magnetism in Hubbard models with long-range interactions
Johannes Dieplinger, Rhine Samajdar, R. N. Bhatt
A wide variety of experimental platforms, ranging from semiconductor quantum-dot arrays to moiré materials, have recently emerged as powerful quantum simulators for studying the Hu…
Quantum Hall criticality in an amorphous Chern insulator
Soumya Bera, Johannes Dieplinger, Naba P Nayak
We explore the critical properties of a topological transition in a two-dimensional, amorphous lattice with randomly distributed points. The model intrinsically breaks the time-rev…
Fragility of surface states in non-Wigner Dyson topological insulators
Alexander Altland, Piet W. Brouwer, Johannes Dieplinger +3
Topological insulators and superconductors support extended surface states protected against the otherwise localizing effects of static disorder. Specifically, in the Wigner-Dyson…
Finite-size prethermalization at the chaos-to-integrable crossover
Johannes Dieplinger, Soumya Bera
We investigate the infinite temperature dynamics of the complex Sachdev-Ye-Kitaev model (SYK) complimented with a single particle hopping term (SYK), leading to the chaos-t…
Topological quantum criticality of the disordered Chern insulator
Mateo Moreno-Gonzalez, Johannes Dieplinger, Alexander Altland
We consider the two-dimensional topological Chern insulator in the presence of static disorder. Generic quantum states in this system are Anderson localized. However, topology requ…
Tricritical point in the quantum Hamiltonian mean-field model
Harald Schmid, Johannes Dieplinger, Andrea Solfanelli +2
Engineering long-range interactions in experimental platforms has been achieved with great success in a large variety of quantum systems in recent years. Inspired by this progress,…
An SYK-inspired model with density-density interactions: spectral & wave function statistics, Green's function and phase diagram
Johannes Dieplinger, Soumya Bera, Ferdinand Evers
The Sachdev-Ye-Kitaev (SYK) model is a rare example of a strongly-interacting system that is analytically tractable. Tractability arises because the model is largely structureless…
Spatial interference between infectious hotspots: epidemic condensation and optimal windspeed
Johannes Dieplinger, Sauro Succi
We discuss the effects of spatial interference between two infectious hotspots as a function of the mobility of individuals (wind speed) between the two and their relative degree o…
