First comprehensive characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films

If there's one thing we humans are good at, it's producing heat: significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, ...

Physicists find a new way to represent π

While investigating how string theory can be used to explain certain physical phenomena, scientists at the Indian Institute of Science (IISc) have stumbled upon on a new series representation for the irrational number π. ...

Researchers unveil the dynamical nature of emergent magnetic monopoles in real magnets for the first time

Magnetic monopoles are elementary particles with isolated magnetic charges in three dimensions. In other words, they behave as isolated north or south poles of a magnet. Magnetic monopoles have attracted continuous research ...

Study reports successful synthesis of centimeter-sized single crystals

A spin liquid is a special state of matter that arises in certain magnetic materials at very low temperatures. Despite its name, it doesn't have anything to do with liquids in the everyday sense. Normally, in a magnet, these ...

The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal

In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction.

Spectral evidence found for Dirac spinons in a kagome lattice antiferromagnet

A new study, published in a recent issue of Nature Physics, sheds light on the long-anticipated emergence of quasiparticles, akin to the famous Dirac particles obeying the relativistic Dirac equation. These quasiparticles, ...

Physicists discover new way to make strange metal

By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff's star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange metal. ...

Large Hadron Collider experiment zeroes in on magnetic monopoles

The late physicist Joseph Polchinski once said the existence of magnetic monopoles is "one of the safest bets that one can make about physics not yet seen." In its quest for these particles, which have a magnetic charge and ...

Beyond equilibrium: Scientists investigate Floquet Fermi liquids

Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in ...

Physicists discover a novel quantum state in an elemental solid

Physicists have observed a novel quantum effect termed "hybrid topology" in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation ...
