Probing Cooper pair momentum by quasiparticle steering with planar Josephson junctions
Isidora Araya Day, Anton R. Akhmerov, Antonio R. L. Manesco
The Cooper pair momentum in a superconductor is associated with a phase gradient of the superconducting order parameter. In general, this momentum is small compared to the Fermi mo…
Topological Gyromorphs
Laura Gómez Paz, Justin Schirmann, Adam Yanis Chaou +2
Gyromorphs are a new class of disordered systems that combine an amorphous-like absence of translational order with quasi-long-range rotational order. Gyromorphs can outperform qua…
Symmetric approximant formalism for statistical topological matter
R. Johanna Zijderveld, Adam Yanis Chaou, Isidora Araya Day +1
The standard approach to characterizing topological matter, computing topological invariants, fails when the symmetry protecting the topological phase is preserved only on average…
Identifying biases of the Majorana scattering invariant
Isidora Araya Day, Antonio L. R. Manesco, Michael Wimmer +1
The easily accessible experimental signatures of Majorana modes are ambiguous and only probe topology indirectly: for example, quasi-Majorana states mimic most properties of Majora…
Kramers-protected hardware-efficient error correction with Andreev spin qubits
Haoran Lu, Isidora Araya Day, Anton R. Akhmerov +2
We propose an architecture for bit-flip error correction of Andreev spins that is protected by Kramers' degeneracy. Specifically, we show that a coupling network of linear inductor…
Scattering theory of higher order topological phases
R. Johanna Zijderveld, Isidora Araya Day, Anton R. Akhmerov
The surface states of intrinsic higher order topological phases are protected by the spatial symmetries of a finite sample. This property makes the existing scattering theory of to…
Pymablock: an algorithm and a package for quasi-degenerate perturbation theory
Isidora Araya Day, Sebastian Miles, Hugo K. Kerstens +2
A common technique in the study of complex quantum-mechanical systems is to reduce the number of degrees of freedom in the Hamiltonian by using quasi-degenerate perturbation theory…
Chiral adiabatic transmission protected by Fermi surface topology
Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco +3
We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the n…
Pfaffian invariant identifies magnetic obstructed atomic insulators
Isidora Araya Day, Anastasiia Varentcova, Daniel Varjas +1
We derive a topological invariant that extends beyond symmetry eigenvalues and Wilson loops and classifies two-dimensional insulators with a symmet…
Topological defects in a double-mirror quadrupole insulator displace diverging charge
Isidora Araya Day, Anton R. Akhmerov, Daniel Varjas
We show that topological defects in quadrupole insulators do not host quantized fractional charges, contrary to what their Wannier representation indicates. In particular, we test…
