Research team finds that the twisted bilayer transition metal dichalcogenide WSe₂ enables the realization of exotic correlated phenomena, including high-Tc superconductivity and correlated insulators, in a controlled manner and without the geometrical restriction found in twisted bilayer graphene. more

Laser light with a broad colour spectrum turns the insulating quasi two-dimensional material La₂CuO₄ (LCO) into a three-dimensional metal. The research, now published in PNAS, reveals that specific vibrations of the crystal lattice are involved in this metallization process. more

Two young researchers from the MPSD’s Theory Department have been chosen for Marie Sklodowska-Curie Research Fellowships. Franco Bonafé and Jin Zhang came to the MPSD in 2019. Their proposals competed with nearly 10.000  applications for the prestigious fellowships. more

The Berry curvature - an important property of quantum materials - can be imaged with chiral light. An international research team has predicted the outcomes of photoelectron spectroscopy experiments and showed that the resulting images reveal information about the microscopic structure of electronic wavefunctions inside atomically thin, two-dimensional materials.  more

Researchers reveal that the possibilities created by stacking two sheets of atomically thin material atop each other at a twist are even greater than expected. Their work provides new insights into the question how a correlated system crosses over from two dimensions to one. more
