Efficient Berry Phase Calculation via Adaptive Variational Quantum Computing Approach
Martin Mootz, Yong-Xin Yao
We present an adaptive variational quantum algorithm to estimate the Berry phase accumulated by a nondegenerate ground state under cyclic, adiabatic evolution of a time-dependent H…

Emergence of flat bands and ferromagnetic fluctuations via orbital-selective electron correlations in Mn-based kagome metal
Subhasis Samanta, Hwiwoo Park, Chanhyeon Lee +6
Kagome lattice has been actively studied for the possible realization of frustration-induced two-dimensional flat bands and a number of correlation-induced phases. Currently, the s…
