Band structure picture for topology in strongly correlated systems with the ghost Gutzwiller ansatz
Ivan Pasqua, Antonio Maria Tagliente, Gabriele Bellomia +3
Understanding the interplay between electronic correlations and band topology remains a central challenge in condensed matter physics, primarily hindered by a language mismatch pro…
Microscopic Theory of Superionic Phase Transitions: Nonadiabatic Dynamics and Many-Body Effects
Jiaming Hu, Zhichao Guo, Jingyi Liang +1
Superionic phase transitions have attracted extensive interest for decades due to their promising applications and rich underlying physics. In particular, complicated many-body eff…
Correlated charge order intertwined with time-reversal symmetry-breaking nodal superconductivity in the dual flat band kagome superconductor CeRuSi
O. Gerguri, P. Krà l, M. Spitaler +19
Kagome materials provide a powerful platform for exploring how flat electronic bands promote symmetry-breaking quantum states, yet studies have so far focused mainly on kagome-deri…
Impact of electronic correlations on the superconductivity of high-pressure CeH
Siyu Chen, Yao Wei, Bartomeu Monserrat +2
Rare-earth superhydrides have attracted considerable attention because of their high critical superconducting temperature under extreme pressures. They are known to have localized…
Pressure-induced trans-proximate correlation in LaNiO and possible routes to enhance its superconductivity
Ruoshi Jiang, Zhiyu Fan, Bartomeu Monserrat +1
We report an unexpected trans-proximate interlayer correlation (stronger correlation between disjoint layers than the adjacent ones) in the high-pressure phase of the recently disc…
Charge order through crystallization of Frenkel excitons: realization in kagome metals
Ruoshi Jiang, Bartomeu Monserrat, Wei Ku
Charge order is a widely observed and representative example of spontaneous broken symmetries in quantum states of matter. Owing to the large intra-atomic Coulomb energy, the charg…
