Inertia of Superconducting Particles in Twisted Trilayer Graphene

The graphene multilayer’s kinetic inductance is both high and tunable, making it a promising material for quantum technologies.




Graphene-based superconductors are a class of materials with many superconducting phases, all of which are tunable by an electric field. One of the hallmarks of superconductivity is kinetic inductance, which quantifies the material’s tendency to oppose a change in current and which arises from the inertia of charge carriers. Rounak Jha at the University of Basel, Switzerland, and his colleagues now report the measurement of tunable kinetic inductance in so-called magic-angle twisted trilayer graphene. Furthermore, they find that this kinetic inductance can be unusually large, making trilayer graphene a promising prospect for superconducting quantum computers and quantum sensors.

The researchers built a superconducting quantum interference device consisting of a loop of superconducting molybdenum-rhenium interrupted by two “weak links” of twisted trilayer graphene. They applied electrical potentials to electrodes above and below the graphene and mapped the change in resistance in the weak links. This procedure pinpointed the temperature and voltage at which the trilayers become superconducting and determined their critical current. Analyzing how this critical current changes in response to a magnetic field for various applied voltages gave the kinetic inductance, which is inversely proportional to the critical current density. These measurements showed that the kinetic inductance can be tuned by altering the field applied via the electrodes and that it can reach 150 nanohenries per square (the units used to quantify thin-film kinetic inductance), 2 orders of magnitude larger than that of commonly used superconductors.

Although trilayer graphene is likely to be harder to scale up than those other materials, the researchers say that it may complement currently available elements and lead to novel superconducting circuits.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Freezing light? Italian scientists froze fastest thing in universe, here’s how

In a rare occurrence, physics made it possible to control the fastest travelling element - light. Italian scientists have managed to freeze the light, as per reports. A recent study published in a British weekly journal reportedly revealed that light can exhibit ‘ supersolid behavior ’ a unique state of matter that flows without friction while retaining a solid-like structure. The research, led by Antonio Gianfate from CNR Nanotec and Davide Nigro from the University of Pavia, marks a significant step in understanding supersolidity in light. The scientists described their findings as “just the beginning” of this exploration, as per reports. In what can be termed as ‘manipulating photons under controlled quantum conditions ’, the scientists demonstrated that light, too, can exhibit this behaviour. (A photon is a bundle of electromagnetic energy which is massless, and travel at the speed of light) How did scientists freeze light? As we know, freezing involves lowering a liquid’s tempera...
