Twisted bilayer graphene (TBG) has garnered significant attention due to its unique electronic properties, especially when the two graphene layers are misaligned by a specific “magic” angle. This misalignment leads to the formation of moiré patterns, resulting in flat electronic bands that enhance electron interactions and give rise to phenomena such as superconductivity and insulating […]
Wandering black holes, a class of black holes that are not anchored to the centres of galaxies, are a fascinating yet elusive aspect of our universe. These black holes are not formed by the typical processes that create stellar black holes, which occur when massive stars run out of fuel and collapse under their own […]
In a recent research, Jonathan D’Emidio and Anders W. Sandvik studied a property of quantum systems called Rényi entanglement entropy (EE) in a specific two-dimensional quantum spin model known as the J-Q model . This model is significant because it describes a type of deconfined quantum criticality , which occurs at a phase transition between […]
Spintronics is a field of technology that focuses on using the spin of electrons—an intrinsic property that can be thought of as a tiny magnetic moment—to store and process information. This concept is based on the fact that electrons, in addition to carrying electric charge, also have a “spin,” which can be oriented in different […]
Scientists seeking better methods for controlling the quantum interactions between light and matter demonstrated a novel way to use light to give electrons a spinning kick. The results of their experiment show that a light beam can reliably transfer orbital angular momentum to itinerant electrons in graphene. Having tight control over the way that light […]
In certain materials, when we apply an electric field (it could be that of light) that vibrates at a certain frequency, it can create a direct current, a steady flow of electrical charge. This current is special because its strength depends on the square of the electric field’s strength. This phenomenon is called “shift current.” […]
Numerous proteins in the cell withstand mechanical loads while performing their function. This is especially significant for cell-surface proteins located in the extracellular matrix, which are essential for the communication between cells in the extracellular milieu. Reacting to mechanical force through conformational changes is crucial for these cell-surface proteins, translating a physical signal into an […]
The term FGK star designates a star the spectrum of which makes it either an F-type star (yellow-white, a bit hotter than then Sun ), a G-type star (yellow, similar to the Sun), or a K-type star (orange, a bit cooler than the Sun). FGK stars come in a variety of sizes but segregating them […]
A new review article stresses out the necessity of the integration of new generation post-quantum cryptography protocols to industrial and critical infrastructures environments. The exponential development of communication technologies in the late 20th century and, specially, in the early 21 st century has resulted in a contemporary society that exists in a hyperconnected world. In […]
A gauge theory is any number of quantum field theories put forward to explain fundamental interactions. In these theories the interactions between particles can be explained by the exchange of particles such as gluons, photons, and W and Z bosons. A gauge theory involves a symmetry group for the fields and potentials (the gauge group) […]
