  The superconducting diode effect, reminiscent of the unidirectional charge
transport in semiconductor diodes, is characterized by a nonreciprocal,
dissipationless flow of Cooper pairs. This remarkable phenomenon arises from
the interplay between symmetry constraints and the inherent quantum behavior of
superconductors. Here, we explore the geometric control of the diode effect in
a kinked nanostrip Josephson junction based on a two-dimensional electron gas
(2DEGs) with Rashba spin-orbit interaction. We provide a comprehensive analysis
of the diode effect as a function of the kink angle and the out-of-plane
magnetic field. Our analysis reveals a rich phase diagram, showcasing a
geometry and field-controlled diode effect. The phase diagram also reveals the
presence of an anomalous Josephson effect related to the emergence of trivial
zero-energy Andreev bound states, which can evolve into Majorana bound states.
Our findings indicate that the exceptional synergy between geometric control of
the diode effect and topological phases can be effectively leveraged to design
and optimize superconducting devices with tailored transport properties.
