Simulating dynamically assisted production of Dirac pairs in gapped graphene monolayers
Ibrahim Akal, Reinhold Egger, Carsten Müller +1
In a vicinity of the Fermi surface, graphene layers with bandgaps allow for closely simulating the vacuum of quantum electrodynamics and, thus, its yet unverified strong-field phen…
Fidelity and visibility reduction in Majorana qubits by entanglement with environmental modes
Morten I. K. Munk, Reinhold Egger, Karsten Flensberg
We study the dynamics and readout of topological qubits encoded by zero-energy Majorana bound states in a topological superconductor. We take into account bosonic modes due to the…
Chiral Y junction of quantum spin chains
F. Buccheri, R. Egger, R. G. Pereira +1
We study a Y junction of spin-1/2 Heisenberg chains with an interaction that breaks both time-reversal and chain exchange symmetries, but not their product nor SU(2) symmetry. The…
Fermi liquid approach for superconducting Kondo problems
A. Zazunov, S. Plugge, R. Egger
We present a Fermi liquid approach to superconducting Kondo problems applicable when the Kondo temperature is large compared to the superconducting gap. To illustrate the theory, w…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Parafermionic generalization of the topological Kondo effect
Kyrylo Snizhko, Francesco Buccheri, Reinhold Egger +1
We propose and study a parafermionic generalization of the topological Kondo effect. The latter has been predicted to arise for a Coulomb-blockaded mesoscopic topological supercond…
