Quantum tunneling in the presence of a topology-changing fermionic bath
Elis Roberts, Jan Behrends, Benjamin Béri
Coupling a quantum particle to a fermionic bath suppresses the particle's amplitude to tunnel, even at zero temperature. While this effect can generally be neglected for gapped bat…
Second-Order Bulk-Boundary Correspondence in Rotationally Symmetric Topological Superconductors from Stacked Dirac Hamiltonians
Elis Roberts, Jan Behrends, Benjamin Béri
Two-dimensional second-order topological superconductors host zero-dimensional Majorana bound states at their boundaries. In this work, focusing on rotation-invariant crystalline t…
Strictly local tensor networks for short-range topological insulators
Shaoyu Yin, Nigel R. Cooper, Benjamin Béri
Despite the success in describing a range of quantum many-body states using tensor networks, there is a no-go theorem that rules out strictly local tensor networks as topologically…
Universality and quantized response in bosonic nonfractionalized tunneling
Shaoyu Yin, Benjamin Béri
We show that tunneling involving bosonic wires and/or boson integer quantum Hall (bIQH) edges is characterized by universal features which are absent in their fermionic counterpart…
Thermal metal-insulator transition in a helical topological superconductor
I. C. Fulga, A. R. Akhmerov, J. Tworzydło +2
Two-dimensional superconductors with time-reversal symmetry have a Z_2 topological invariant, that distinguishes phases with and without helical Majorana edge states. We study the…
Dephasing-enabled triplet Andreev conductance
B. Béri
We study the conductance of normal-superconducting quantum dots with strong spin-orbit scattering, coupled to a source reservoir using a single-mode spin-filtering quantum point co…
