Excitation factors and exceptional points of Kerr-de Sitter quasinormal modes
Dario Rossi, Naritaka Oshita, Leonardo Gualtieri +1
We compute the excitation factors of Kerr-de Sitter black hole quasinormal modes using two different techniques: a Heun function representation and an expansion of the solution in…
Precision quantum simulation of magnon spectra and interactions
Trond I. Andersen, Nikita Astrakhantsev, Jeronimo Martinez +329
Quantum simulation promises to advance materials discovery by accurately simulating complex states of matter, their microscopic excitations, and macroscopic response functions. The…
Minimum mass, maximum charge and hyperbolicity in scalar Gauss-Bonnet gravity
Dario Rossi, Leonardo Gualtieri, Thomas P. Sotiriou
We study the loss of hyperbolicity of perturbation equations for black hole solutions of scalar Gauss-Bonnet gravity. We consider a class of coupling functions allowing for static…
Thermalization and Criticality on an Analog-Digital Quantum Simulator
Trond I. Andersen, Nikita Astrakhantsev, Amir H. Karamlou +224
Understanding how interacting particles approach thermal equilibrium is a major challenge of quantum simulators. Unlocking the full potential of such systems toward this goal requi…
Schwinger boson study of the -- kagome Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interactions
D. Rossi, J. Motruk, L. Rademaker +1
Schwinger boson mean field theory is a powerful approach to study frustrated magnetic systems which allows to distinguish long range magnetic orders from quantum spin liquid phases…
Kagome chiral spin liquid in transition metal dichalcogenide moiré bilayers
Johannes Motruk, Dario Rossi, Dmitry A. Abanin +1
At filling of the moiré flat band, transition metal dichalcogenide moiré bilayers will develop kagome charge order. We derive an effective spin model for the resulting loca…
