Science Daily August 23, 2023 Quantum magnets provide a powerful platform to explore complex quantum many-body phenomena. One example is triplon excitations, exotic many-body modes emerging from propagating singlet-triplet transitions. Researchers in Finland engineered a minimal quantum magnet from organic molecules and demonstrated the emergence of dispersive triplon modes in one- and two-dimensional assemblies probed with scanning tunneling microscopy and spectroscopy. According to the researchers their results provide the first demonstration of dispersive triplon excitations from a real-space measurement… read more. TECHNICAL ARTICLE

Nanowerk November 26, 2021 Using Floquet engineering researchers in Germany created a Rydberg states in an ultracold atomic gas. By applying a sequence of spin manipulations, they changed the symmetry properties of the Hamiltonian modifying the relaxation behavior of the total spin. According to the researchers engineering a wide range of Hamiltonians opens vast opportunities for implementing quantum simulation of nonequilibrium dynamics in a single experimental setting. The studies are an important step towards a better understanding of basic processes in complex quantum systems…read more. TECHNICAL ARTICLE
