The spontaneous emergence of 1D superconducting stripes at a 2D interface in an oxide heterostructure
Unconventional superconducting states are states of superconductivity rooted in physical processes that do not conform with the conventional theory of superconductivity, namely Bardeen, Cooper and Schrieffer (BCS) theory. These states are characterized by close...
Study unveils a new family of quantum anomalous Hall insulators
In recent years, physicists and material scientists have identified various new materials marked by interesting properties and quantum effects. These materials could prove highly valuable both as platforms to study quantum effects and for the development of new...
A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations
Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying systems comprised of several strongly...
Using mode-locked lasers to realize and study non-Hermitian topological physics
Mode-locked lasers are advanced lasers that produce very short pulses of light, with durations ranging from femtoseconds to picoseconds. These lasers are widely used to study ultrafast and nonlinear optical phenomena, but they have also proved useful for various...
Study outlines spectroscopic signatures of fractionalization in octupolar quantum spin ice
Quantum spin liquids are fascinating quantum systems that have recently attracted significant research attention. These systems are characterized by a strong competition between interactions, which prevents the establishment of a long-range magnetic order, such as...
An approach to design high-power lithium sulfur batteries
Lithium–sulfur (Li–S) batteries are a promising alternative to lithium–ion batteries (LiBs), the most common rechargeable battery technology. As sulfur is abundant on Earth, these batteries could be cheaper and more environmentally friendly than LiBs, while also...
Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013.
Evidence of phonon chirality from impurity scattering in the antiferromagnetic insulator strontium iridium oxide
The thermal hall effect (THE) is a physical phenomenon characterized by tiny transverse temperature differences occurring in a material when a thermal current passes through it and a perpendicular magnetic field is applied to it. This effect has been observed in a...
Researchers offer theoretical description of topological water wave structures
Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices and skyrmions, have attracted significant...
