How come today is the quantum day? I thought ħ=1.

❓ How do you compute the topological invariant of a Majorana device? ❓ Topological invariants are unambiguous in the thermodynamic limit. But real-life devices are finite and often connected to other components, such as leads, tunnel barriers, etc. How do we compute the invariant of such a device?

🚨 NEW PUBLICATION ALERT! 🚨 We show how to probe valleys in graphene with a gate-defined device: no optical or magnetic control is needed, only voltages. We also propose experiments using this tool to probe quantum dots, and symmetry-broken phases in large samples. scipost.org/SciPostPhys....

Not only a half-measure, but from experience arbitrary timelines often result in no code availability at all. I'm still waiting for authors who promised to publish code after acceptance by a journal, for example.

Quantum Hall devices show chiral transport as long as the edge states are far from each other. But what if I tell you there is a way to observe chiral transport even if quasiparticles meet at a single point? That's what we show in our latest manuscript! arxiv.org/abs/2311.17160
