Amplified response of cavity-coupled quantum-critical systems
Shouvik Sur, Yiming Wang, Mounica Mahankali +2
A quantum critical point develops when matter undergoes a continuous transformation between distinct ground states at absolute zero. It hosts pronounced quantum fluctuations, which…
Weyl nodes in CeRuSn studied by dynamical mean-field theory
Jorūnas Dobilas, Martin Brass, Frank T. Ebel +2
The heavy fermion compound CeRuSn was recently shown to exhibit a spontaneous nonlinear Hall effect, indicating its topological nature. This is consistent with the lack of…
Tracking flat bands via phonon-mediated interband scattering
Fabian Garmroudi, Jennifer Coulter, Xinlin Yan +7
Flat-band (FB) systems offer a fertile platform for realizing exotic correlated and topological phases, yet central challenges remain in tuning FBs towards the Fermi level $E_\text…
Suppression of shot noise at a Kondo destruction quantum critical point
Yiming Wang, Shouvik Sur, Fang Xie +4
Strange metal behavior has been observed in an expanding list of quantum materials, with heavy fermion metals serving as a prototype setting. Among the intriguing questions is the…
Crystal field excitations in rattling clathrate CeBaAuSi
Michelangelo Tagliavini, Federico Mazza, Xinlin Yan +6
We investigate the local crystal-field environment of cerium in the clathrate compound CeBaAuSi (Ce-BAS) using resonant inelastic x-ray scattering (RIXS) and magneti…
Correlated flat-band physics in a bilayer kagome metal based on compact molecular orbitals
Mounica Mahankali, Fang Xie, Yuan Fang +11
Flat bands, when located close to the Fermi energy, can considerably enhance the influence of electron correlations on the low energy physics in kagome and other frustrated-lattice…
