Entropy measurements in mesoscopic systems

Schematics of a proposed entropy measurement of a Majorana qubit. From: Phys. Rev. Lett. 123, 147702 (2019)

Strain Engineering in Graphene

Graphene ribbon oriented along the armchair direction, with a uniaxial stretch generating a larger deformationat its narrow (top) end. The resulting strain gradient is designed via the shape function W(y) to create a uniformpseudomagnetic field B.

Symmetry-resolved entanglement in many-body systems

(a) An example of a 3-sheet Riemann surface geometry with an inserted space-time AharonovBohm flux α. (b) A generic many body wavefunction is a superposition of subsystem charge states. From: Phys. Rev. Lett. 120, 200602 (2018)

Surface code setup

Pairs of normal leads (indicated by vertical lines for clarity) are tunnel coupled to MBSs γ1 and γ2 located on different boxes. The two-terminal conductance measurement provides information about plaquettes OA and OB. Using SETs in the external circuit, plaquettes can be flipped. From: Phys. Rev. Lett. 116, 050501 (2016).
