Local thermodynamic measurements of a twisted transition metal dichalcogenide heterostructure reveal competition between unconventional charge order and Hofstadter states. This results from the presence of both flat and dispersive electronic bands, whose energetic ordering can be experimentally tuned.
A trilayer copper oxide superconductor, which exhibits the highest superconducting critical temperature as a function of the number of copper–oxygen planes, is shown to have unusual doped hole distribution and interaction between the planes.
The interplay between flat and dispersive bands in moiré materials has not yet been examined in detail. Now, the phase diagram of a transition metal dichalcogenide bilayer shows correlated states arising from both types of band.
Wrinkling of cell nuclei is associated with disease. During development, the nucleus behaves like a sheet of paper and the wrinkling amplitude can be manipulated without changing its pattern.
Hubbard excitons are elusive quasiparticles that are predicted to form in strongly correlated insulators. Detecting their internal structure and dynamics clarifies the involvement of spin fluctuations in their binding and recombination processes.
Measurements of the electronic structure of a trilayer cuprate superconductor suggest that its high critical temperature is explained by the different doping levels of the layers. The combination of underdoped inner layer and overdoped outer layers supports superconductivity.
Hole and particle-like quasiparticles of a Mott insulator can pair into excitonic bound states. Now, time-resolved measurements of Sr2IrO4 show signs of an excitonic fluid forming from a photo-excited population of quasiparticles.
Phonons that carry a large magnetic moment may be helpful for creating spintronic devices. Now this phenomenon is observed in an antiferromagnet and is enhanced by the critical fluctuations associated with a phase transition.
Claims of a room-temperature, ambient-pressure superconductor recently kicked up a storm on social media. As the dust settles, we take stock of what this experience can teach us.
Originally invented to improve cornering techniques in race driving, speed traps contribute to road safety. Robert Wynands introduces us to tools of traffic metrology.
Quantum computers may help to solve classically intractable problems, such as simulating non-equilibrium dissipative quantum systems. The critical dynamics of a dissipative quantum model has now been probed on a trapped-ion quantum computer.
The liquid-crystal-like order of cells in epithelial tissues aids rearrangements, but there is disagreement over the dominant liquid crystal phase. Now, a unified approach reveals that two distinct symmetries dominate at different scales.
Cells in a tissue layer arrange themselves in orientationally ordered structures. Now two types of liquid crystalline order have been shown to coexist, with nematic order dominating large length scales and hexatic order dominating small length scales.
Cooper pairs that form with finite centre-of-mass momentum are rare. Now there is evidence that this can happen below the Pauli limit in a bilayer material.
