Scientists Just Discovered a Strange Material That Breaks the Rules of Physics
A team led by UChicago Pritzker Molecular Engineering has discovered materials that defy convention, shrinking when heated and expanding under pressure, marking a breakthrough in fundamental science. What expands when crushed, shrinks when…

Electromagnetic response in dipole superfluids
Magnetic-dipole superfluid
We first focus on the magnetic-dipole superfluids under external electric field. We assume that bosons with a constant magnetic moment μ = μez form a Bose-Einstein condensate, where ez is a unit vector along the…

QKD protected fiber-based infrastructure for time dissemination
Encrypted WR-PTP
We consider QKD and WR-PTP transmission in the end-to-end infrastructure that connects IQB nodes in INRiM and Thales Alenia Space Italy (TASI) premises, both in Rome. INRiM is the Alice (A) node, while Bob (B) node is in TASI. A…

Causal network inference based on cross-validation predictability
Causality detection based on cross-validation predictability
The causality from CVP method is a statistical concept based on cross-validation prediction of observed data. Assuming two variables \(X\) and \(Y\) are observed in m samples, we…

Zero-field Hall effect emerging from a non-Fermi liquid in a collinear antiferromagnet V1/3NbS2
Single crystal growth
The V1/3NbS2 single crystals were synthesized by the chemical vapor transport method using iodine as the transport agent. We first obtained polycrystalline samples by heating stoichiometric amounts of high-purity vanadium…

Hilbert space fragmentation at the origin of disorder-free localization in the lattice Schwinger model
The dynamical phase diagram of the lattice Schwinger model
The Schwinger model describes quantum electrodynamics on a one-dimensional (1D) lattice96. In the Wilson formulation1, the model describes the coupling between matter fields that reside on…

Spin-valley coupling enhanced high-TC ferromagnetism in a non-van der Waals monolayer Cr2Se3 on graphene
Fabrication and characterization of ML Cr2Se3
First, we present fabrication and characterization of a ML Cr2Se3 film. Since Cr chalcogenides are stabilized with a few different chemical compositions such as CrSe2 (12…
