How humans across cultures and historical periods conceptualize relationships
Throughout the course of their lives, humans are known to establish and navigate an intricate web of social relationships, ranging from friendships to family bonds, romances, acquaintances, professional relationships and, today, online interactions. Over the past...
Thermopower-based technique can detect fractional quantum Hall states
If one side of a conducting or semiconducting material is heated while the other remains cool, charge carriers move from the hot side to the cold side, generating an electrical voltage known as thermopower.
The first comprehensive characterization of unconventional superconductivity arising from multipolar moments
Superconductivity is a quantum phenomenon, observed in some materials, that entails the ability to conduct electricity with no resistance below a critical temperature. Over the past few years, physicists and material scientists have been trying to identify materials...
Study uncovers origin of the large neutron-capture cross section in ⁸⁸Zr using new methodology
Studies that explore how the denser sections of atoms, known as atomic nuclei, interact with neutrons (i.e., particles with no electric charge) can have valuable implications both for the understanding of these atoms' underlying physics and for the development of...
AMoRE experiment sets new limits on neutrinoless double beta decay of ¹⁰⁰Mo
In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as neutrinoless double beta (0νββ) decay. This is a rare process that entails the simultaneous decay of two neutrons in a nucleus into two protons,...
An experimental test of the nonlocal energy alteration between two quantum memories
Quantum technologies operate by leveraging various quantum mechanical effects, including entanglement. Entanglement occurs when two or more particles share correlated states even if they are distant.
Wireless terahertz cryogenic interconnect minimizes heat-to-information transfer in quantum processors
Quantum computers, devices that process information leveraging quantum mechanical effects, could outperform classical computers in some complex optimization and computational tasks. However, before these systems can be adopted on a large-scale, some technical...
Thermomajorization theory provides new framework for quantifying mysterious Mpemba effect
The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when they are warm or colder. This effect was observed in various systems, including water, which sometimes freezes faster when it is hot than when it...
The first observation of amplified spontaneous emission from electron-hole plasma in 2D semiconductors
Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by excited particles, due to photons of the same frequency triggering further emissions. This phenomenon is central to the functioning of various...
