A recent study found that the Hubbard model failed to accurately predict the behavior of a simplified one-dimensional cuprate system. According to scientists at SLAC, this suggests the model is unlikely to fully account for high-temperature superconductivity in two-dimensional cuprates.
Superconductivity, the phenomenon where certain materials can conduct electricity without any energy loss, holds great potential for revolutionary technologies, from ultra-efficient power grids to cutting-edge quantum devices.
A recent study published in Physical Review Letters.
A mysterious menagerie of quantum states — once purely theoretical — has been brought to life by researchers at Columbia using twisted molybdenum ditelluride.
These newly observed states, some never seen before, hint at the possibility of topological quantum computers that don’t require magnetic fields, overcoming a major obstacle in the field. By employing a highly sensitive optical technique, scientists have not only identified a range of exotic quantum states but also demonstrated a new experimental approach that may transform the way we study quantum matter.
Working with the Quantum Statistical Physics (PQS) group, Dengis developed a protocol for rapidly generating NOON states. “These states, which look like miniature versions of Schrödinger’s famous cat, are quantum superpositions,” he explains. “They are of major interest for technologies such as ultra-precise quantum sensors or quantum computers.”
The obstacle of time
The main challenge? Manufacturing these states normally takes far too long. We’re talking tens of minutes or more, which often exceeds the lifetime of the experiment. The cause? An energy bottleneck, a “sharp bend” in the system’s evolution that forces it to slow down.
A demonstration of Bell-operator correlations in a 73-qubit quantum processor provides a benchmark for studying quantum nonlocality in complex systems that goes beyond standard measurements of entanglement.
IN A NUTSHELL 🚀 A new propulsion technology claims to revolutionize space travel by generating thrust without expelling propellant, challenging established physical laws. 📚 The concept echoes the controversial EmDrive, which failed scientific validation, highlighting the need for rigorous testing of bold claims. 🌟 Charles Buhler and his team, including experts from NASA and Blue
Two tiny aluminum drumheads. A temperature colder than space. And a secret experiment that’s changing everything we thought we knew about reality. In this video, we reveal the mind-blowing story behind the Quantum Drum Experiment — where scientists pushed the limits of the Heisenberg Uncertainty Principle and opened a portal to a new era of quantum measurement. With fog swirling in a cryogenic chamber, these drums don’t just make sound — they bend the rules of the universe.

“Metaphysical Experiments: Physics and the Invention of the Universe” by Bjørn Ekeberg Book Link: https://amzn.to/4imNNk5
“Metaphysical Experiments, Physics and the Invention of the Universe,” explores the intricate relationship between physics and metaphysics, arguing that fundamental metaphysical assumptions profoundly shape scientific inquiry, particularly in cosmology. The author examines historical developments from Galileo and Newton to modern cosmology and particle physics, highlighting how theoretical frameworks and experimental practices are intertwined with philosophical commitments about the nature of reality. The text critiques the uncritical acceptance of mathematical universality in contemporary physics, suggesting that cosmology’s reliance on hypological and metalogical reasoning reveals a deep-seated faith rather than pure empirical validation. Ultimately, the book questions the limits and implications of a science that strives for universal mathematical truth while potentially overlooking its own inherent complexities and metaphysical underpinnings. Chapter summaries: - Cosmology in the Cave: This chapter examines the Large Hadron Collider (LHC) in Geneva to explore the metaphysics involved in the pursuit of a “Theory of Everything” linking subatomic physics to cosmology. - Of God and Nature: This chapter delves into the seventeenth century to analyze the invention of the universe as a concept alongside the first telescope, considering the roles of Galileo, Descartes, and Spinoza. - Probability and Proliferation: This chapter investigates the nineteenth-century shift in physics with the rise of probabilistic reasoning and the scientific invention of the particle, focusing on figures like Maxwell and Planck. - Metaphysics with a Big Bang: This chapter discusses the twentieth-century emergence of scientific cosmology and the big bang theory, shaped by large-scale science projects and the ideas of Einstein and Hawking. - Conclusion: This final section questions the significance of large-scale experiments like the JWST as metaphysical explorations and reflects on our contemporary scientific relationship with the cosmos.
A new theory proposes gravity isn’t a fundamental force but emerges from quantum electromagnetic interactions, potentially reshaping our view of spacetime itself.
