Physicists at the University of Bonn and the University of Kaiserslautern-Landau (RPTU) have created a one-dimensional gas out of light. This has enabled them to test theoretical predictions about the transition into this exotic state of matter for the first time. The method used in the experiment by the researchers could be used for examining quantum effects. The results have been published in the journal “Nature Physics.”

Now MIT physicists have directly observed edge states in a cloud of ultracold atoms. For the first time, the team has captured images of atoms flowing along a boundary without resistance, even as obstacles are placed in their path. The results, which appear today in Nature Physics, could help physicists manipulate electrons to flow without friction in materials that could enable super-efficient, lossless transmission of energy and data.

In recent theoretical research, Ge and collaborators Jiru Liu and M. Suhail Zubairy, members of the Institute for Quantum Science and Engineering at Texas A&M University, explored the relationship between the two fundamental resources to quantum physics. They established a single way to quantify the two properties, defining a mathematical description of each. Their paper, “Classical-Nonclassical Polarity of Gaussian States,” was published in the prestigious Physical Review Letters.

Researchers from Skoltech, Universitat Politècnica de València, Institute of Spectroscopy of RAS, University of Warsaw, and University of Iceland have demonstrated the spontaneous formation and synchronization of multiple quantum vortices in optically excited semiconductor microcavities.

Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics? A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

ICFO leads the first experimental demonstration of a deep subwavelength topological edge state within a nanophotonic system, a turnover in the field of topological Nanophotonics.

Atomic clocks have been used for decades – but now, even greater precision has become possible: TU Wien (Vienna) and JILA/NIST are presenting the world's first nuclear clock.

Scientists at EPFL, the Helmholtz-Zentrum Berlin and Freie Universität Berlin have uncovered intriguing insights into the magnetic properties of a complex material that dances on the edge of quantum spin liquid behavior. The discovery could have far-reaching implications for our understanding of quantum materials and their potential technological applications.

Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because they have recently been found to host novel fascinating unobserved physical phenomena and exotic phases of matter.

In a recent study published in Physical Review Letters, Dr. Manik Banik from the S. N. Bose National Centre for Basic Sciences, an autonomous institute of the Department of Science and Technology, along with collaborators from the Indian Statistical Institute Kolkata, A B N Seal College Cooch Behar, and the University of Hong Kong, demonstrated that a universal standard for measuring quantum nonlocality is impossible.
