Quantum Simulation: First Signs of Stripe Formation
Quantum Simulation: First Signs of Stripe Formation
In a new study, researchers from the MCQST, the Max Planck Institute of Quantum Optics and the LMU under the lead of Timon Hilker demonstrated evidence of stripe formation, i.e. extended structures in the density pattern, in a cold-atom Fermi-Hubbard system. By using a quantum gas microscope and a special mixed-dimensional geometry, they were able to observe unique higher-order correlations in spin and charge densities related to those seen in some high-temperature superconducting materials.

In a cold-atom Fermi Hubbard model, researchers observed extended and attractive correlations between hole dopants and indications of stripes that are associated with superconductivity, opening up novel insights into the behaviour of exotic quantum phases.
Simulating the Quantum World: Purdue Researchers Get Cold With ‘Quantum Coarsening’
Simulating the Quantum World: Purdue Researchers Get Cold With ‘Quantum Coarsening’
Using supercold environments and a quantum computer, Purdue researchers examined the evolution of a network of Ising spins in the presence of a transverse field. Much like ripples on water, the wave moves across the surface, but the water molecules move up and down, perpendicular to the wave's direction. This type of computational discovery is challenging with conventional or even supercomputers. This discovery, led by Arnab Banerjee, an assistant professor at Purdue University's Department of Physics and Astronomy, has been published in Nature Communications.

POSTECH and Japan’s NIMS Identify Edge Dependence of Electron Transport in Bilayer Graphene
Electron transport in bilayer graphene exhibits a pronounced dependence on edge states and a nonlocal transport mechanism, according to a recent study led by Professor Gil-Ho Lee and Ph.D. candidate Hyeon-Woo Jeong of POSTECH’s Department of Physics, in collaboration with Dr. Kenji Watanabe and Dr. Takashi Taniguchi at Japan’s National Institute for Materials Science (NIMS). The findings were published in the international nanotechnology journal Nano Letters.
