Generation of many-body Bell correlated states in optical lattices

OPTOlogic researchers from ICFO, in collaboration with the University of Warsaw and the Institute of Physics, Polish Academy of Sciences, show how to generate many-body Bell correlated states using ultracold quantum gases in optical lattices.  Quantum correlations are a fundamental aspect of quantum mechanics. They refer to the correlations between the outcomes of measurements performed […]

Abelian-Higgs mechanism in 1+1 dimension

A team of researchers uncovers hidden gems lurking behind the Abelian-Higgs model in one spatial dimension and time. While universal fault-tolerant quantum computing with error correction remains elusive, the future belongs to special-purpose quantum computers, i.e. quantum simulators. Although there are no rigorous proofs, the physics community strongly believes that quantum simulators have already led […]

Topological Quantum Critical Points in the Extended Bose Hubbard Model

  Exploring Topological Quantum Critical Points A recent study published in Physical Review Letters predicted the existence of a new state of matter: quantum critical points with topological properties occurring in the paradigmatic strongly-correlated extended Bose-Hubbard model. Condensed Matter Physics and Topological Phases Condensed matter physics deals with systems of many interacting particles which can […]

A scientific competition assesses methods for anomalous diffusion

The study analyzes the results of a community effort and determines that machine learning greatly improves the estimation of the properties of diffusing particles. Since Albert Einstein provided a theoretical foundation for Robert Brown’s observation of the erratic or unpredictable movement of microscopic particles suspended within pollen grains, significant new findings that deviate quite a […]

Lighting it up: fast material manipulation through a laser

Researchers from the Physical Chemistry Department of the Fritz Haber Institute and the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg have found out that ultrafast switches in material properties can be prompted by laser pulses – and why. This knowledge may enable new transistor concepts. Advancing Transistor Technology with Light Making the speed of […]
