“…This is a supercurrent diode effect (first envisioned in Ref. [29]), which has been first demonstrated in bulk superconductors [30] and then in JJs [28]. In both cases, the SOI was of Rashba-type and the supercurrent rectification driven by the in-plane field perpendicular to the current.…”

Simultaneous breaking of inversion- and time-reversal symmetry in Josephson junction leads to a possible violation of the I(ϕ) = −I(−ϕ) equality for the current-phase relation. This is known as anomalous Josephson effect and it produces a phase shift ϕ0 in sinusoidal current-phase relations. In ballistic Josephson junctions with non-sinusoidal current phase relation the observed phenomenology is much richer, including the supercurrent diode effect and the magnetochiral anisotropy of Josephson inductance. In this work, we present measurements of both effects on arrays of Josephson junctions deﬁned on epitaxial Al/InAs heterostructures. We show that the orientation of the current with respect to the lattice affects the magnetochiral anisotropy, possibly as the result of a ﬁnite Dresselhaus component. In addition, we show that the two-fold symmetry of the Josephson inductance reﬂects in the activation energy for phase slips.

“…Transistors fabricated of atomically thin graphene layers (2D) might become an integral part of postsilicon microprocessors [5,6]. Furthermore, 3D superstructures of thin metal layers-arranged in the right way to break inversion symmetry-might provide promising candidates for diodes in superconducting electronics [7].…”

We investigate pressure-induced structural changes to the Peierls-type distorted low-temperature phase of the low-dimensional Sc 3 CoC 4 as a possible origin of its pressure-enhanced superconductivity. By means of cryogenic high-pressure x-ray diffraction experiments we could reveal subtle, but significant structural differences between the low-temperature phase at ambient and elevated pressures. We could thus establish the structure of the superconducting phase of the title compound, which interestingly still shows the main features of the Peierls-type distorted low-temperature phase. This indicates that in contrast to other low-dimensional materials a suppression of periodic structural distortions is no prerequisite for superconductivity in the transition-metal carbide.

“…Note that other reports claiming electrical MChA have been published, concerning systems that are noncentrosymmetric but not chiral and that show nonreciprocal resistance with respect to a magnetic field. 61,62 A symmetry-allowed expansion can also be made for the transmission probability of spin polarized electrons through chiral molecules, leading to a spin-filtering effect referred to as chirality induced spin selectivity (CISS):…”

Magneto‐chiral anisotropy: From fundamentals to perspectives

et al. 2021

The interplay between chirality and magnetic fields gives rise to a cross effect referred to as magneto-chiral anisotropy (MChA), which can manifest itself in different physical properties of chiral magnetized materials. The first experimental demonstration of MChA was by optical means with visible light. Further optical manifestations of MChA have been evidenced across most of the electromagnetic spectrum, from terahertz to X-rays. Moreover, exploiting the versatility of molecular chemistry toward chiral magnetic systems, many efforts have been made to identify the microscopic origins of optical MChA, necessary to advance the effect toward technological applications. In parallel, the replacement of light by electric current has allowed the observation of nonreciprocal electrical charge transport in both molecular and inorganic conductors as a result of electrical MChA (eMChA). MChA in other domains such as sound propagation, photochemistry, and electrochemistry are still in their infancy, with only a few experimental demonstrations, and offer wide perspectives for further studies with potentially large impact, like the understanding of the homochirality of life. After a general introduction to MChA, we give a complete review of all these phenomena, particularly during the last decade.
