Mapping the metal-insulator phase diagram by algebraically fast-forwarding dynamics on a cloud quantum computer
Thomas Steckmann, Trevor Keen, Efekan Kökcü +3
Dynamical mean-field theory (DMFT) maps the local Green's function of the Hubbard model to that of the Anderson impurity model and thus gives an approximate solution of the Hubbard…

Quantum fluctuations of charge order induce phonon softening in a superconducting cuprate
H. Y. Huang, A. Singh, C. Y. Mou +13
Quantum phase transitions play an important role in shaping the phase diagram of high-temperature cuprate superconductors. These cuprates possess intertwined orders which interact…

Flatband-Induced Itinerant Ferromagnetism in RbCoSe
Jianwei Huang, Zhicai Wang, Hongsheng Pang +8
CoSe (=K,Rb,Cs) is a homologue of the iron-based superconductor, FeSe. From a comprehensive study of RbCoSe via measurements of magnetization, tran…
