Many-Body Entanglement Properties of Finite Interacting Fermionic Hamiltonians
Irakli Giorgadze, Grayson Welch, Haixuan Huang +2
We analyze many-body entanglement in interacting fermionic systems by using the -body reduced density matrix. We demonstrate that if a particle number conserving fermionic Hamil…
Topological Floquet Green's function zeros
Elio J. König, Aditi Mitra
Motivated by recent advances in digital quantum emulation using noisy intermediate-scale quantum (NISQ) devices and an increased interest in topological Green's function zeros in c…
Anomalous Hall effect in rhombohedral graphene
Vera Mikheeva, Daniele Guerci, Daniel Kaplan +1
Motivated by recent experiments on rhombohedral stacked multilayer graphene and the observation of the anomalous Hall effect in a spontaneous spin-valley polarized quarter metal st…
Topologically enabled superconductivity: possible implications for rhombohedral graphene
Francesca Paoletti, Daniele Guerci, Giorgio Sangiovanni +2
We present a topological mechanism for superconductivity emerging from Chern-2 insulators. While, naively, time-reversal symmetry breaking is expected to prevent superconductivity,…
Design and benchmarks for emulating Kondo dynamics on a quantum chip
Soumyadeep Sarma, Jukka I. Väyrynen, Elio J. König
Motivated by recent advances in digital quantum simulation and the overall prospective of solving correlated many-electron problems using quantum algorithms, we design a gate-based…
Emulating moiré materials with quasiperiodic circuit quantum electrodynamics
Tobias Herrig, Christina Koliofoti, Jedediah H. Pixley +2
Topological bandstructures interfering with moiré superstructures give rise to a plethora of emergent phenomena, which are pivotal for correlated insulating and superconducting sta…

Motivated by the exotic phenomenology of certain quantum materials and recent advances in programmable quantum emulators, we here study fermions and bosons in lattice…
Type-II heavy Fermi liquids and the magnetic memory of 4Hb-TaS
Elio J. König
The interplay of quantum spin liquids with itinerant conduction electrons is of crucial interest for understanding layered structures composed of frustrated magnet and metal monola…
Mott insulators with boundary zeros
Niklas Wagner, Lorenzo Crippa, Adriano Amaricci +9
The topological classification of electronic band structures is based on symmetry properties of Bloch eigenstates of single-particle Hamiltonians. In parallel, topological field th…
Quasiperiodic circuit quantum electrodynamics
Tobias Herrig, Jedediah H. Pixley, Elio J. König +1
Superconducting circuits are an extremely versatile platform to realize quantum information hardware and to emulate topological materials. We here show how a simple arrangement of…
Visualizing the multifractal wavefunctions of a disordered two-dimensional electron gas
Berthold Jäck, Fabian Zinser, Elio J. K\" onig +5
The wavefunctions of a disordered two-dimensional electron gas at the quantum-critical Anderson transition are predicted to exhibit multifractal scaling in their real space amplitu…
Renormalization group analysis for the quasi-1D superconductor BaFeS
Elio J. König, Alexei M. Tsvelik, Piers Coleman
Motivated by the discovery of superconductivity in the two-leg, quasi-one dimensional ladder compound, BaFeS we present a renormalization group study of electrons moving on…
Universal fidelity near quantum and topological phase transitions in finite 1D systems
E. J. König, A. Levchenko, N. Sedlmayr
We study the quantum fidelity (groundstate overlap) near quantum phase transitions of the Ising universality class in one dimensional (1D) systems of finite size L. Prominent examp…
