Phase-Topology Classification of Memristor Hysteresis Loops via Self-Crossings

Ovidiu-Zeno Lipan, Eric Neuhaus, Rafael Schio Wengenroth Silva +6

Memristive devices have revolutionized non-volatile memory and neuromorphic computing, yet the geometry of their hysteresis loops -- in particular, the occurrence and robustness of…

Complete coherent control of spin qubits in self-assembled InAs quantum dots under oblique magnetic fields

I. Samaras, K. Barr, C. Schneider +2

We demonstrate complete coherent control of a single spin qubit confined in a self-assembled InAs negatively charged quantum dot subjected to an Oblique magnetic field, and directl…

Momentum-space non-Hermitian skin effect in an exciton-polariton system

Yow-Ming, Hu, Mateusz Król +11

Localization of a macroscopic number of eigenstates on a real-space boundary, known as the non-Hermitian skin effect, is one of the striking topological features emerging from non-…

Probing Local Topology in a Disordered Higher-Order Topological Insulator

Johannes Düreth, Simon Widmann, Philipp Gagel +13

Higher-order topology is prized for its ability to realize lower-dimensional boundary states which are stable beyond fine-tuning. However, disorder presents a failure mechanism tha…

Direct experimental access to the bulk band inversion in a topological metamaterial

Simon Widmann, Johannes Düreth, Siddhartha Dam +9

Topological phases in exciton-polaritons and other metamaterial platforms have attracted significant attention due to their flexibility as Hamiltonian simulators. In previous works…
