Robust Signatures of Fragile Topology
Viktor Könye, Ihor Nimyi, Oleg Janson +3
Some topological phases of matter are called fragile. They do not generically host protected gapless boundary states and they can be trivialized by adding additional valence bands.…
Synthetic horizons in an atomic chain: Horizon-induced effects and connections to quantum Hall systems
Ali G. Moghaddam, Viktor Könye, Lotte Mertens +2
We investigate the sine model, a one-dimensional tight-binding Hamiltonian with position-dependent sinusoidal hopping, and demonstrate the formation of synthetic horizons where ele…
Topological classification of crystalline insulators through band structure combinatorics
Jorrit Kruthoff, Jan de Boer, Jasper van Wezel +2
We present a method for efficiently enumerating all allowed, topologically distinct, electronic band structures within a given crystal structure. The algorithm applies to crystals…
A Nanoscale Experiment Measuring Gravity's Role in Breaking the Unitarity of Quantum Dynamics
Jasper van Wezel, Tjerk H. Oosterkamp
Modern, state of the art nanomechanical devices are capable of creating spatial superpositions that are massive enough to begin to experimentally access the quantum to classical cr…
