Quantum Fisher information of magnetic quantum phase transition on Kondo lattice
Yuan Fang, Lei Chen, Mounica Mahankali +4
Strange metals exemplify highly collective quantum many-body systems that call for new means of characterization, and there is considerable potential for quantum information approa…
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…
Resolving the Kagome Origin of the Strange Metallicity in NiIn
Jean C. Souza, Moshe Haim, Ambikesh Gupta +15
Strong correlations promote singular properties such as strange metallicity, which shows considerable commonality across quantum materials platforms. Understanding the mechanism fo…
Spectral singularity enhances transverse spin
Mounica Mahankali, Sudipta Saha, Nirmalya Ghosh +1
We study the transverse spin and the Belinfante spin momentum in a gain-loss balanced waveguide, known to be one of the first and most studied examples of -symmetric…
