The Kondo Cloud in a 1D Nanowire
Joseph Kleinhenz, Igor Krivenko, Guy Cohen +1
A recent experiment [Nature 579, 210--213 (2020)] probed the extent of the Kondo cloud in 1D by measuring the effect of electrostatic perturbations applied a distance away from…
Unconventional Hund Metal in a Weak Itinerant Ferromagnet
Xiang Chen, Igor Krivenko, Matthew B. Stone +6
The physics of weak itinerant ferromagnets is challenging due to their small magnetic moments and the ambiguous role of local interactions governing their electronic properties, ma…
Dynamics of Kondo voltage splitting after a quantum quench
Igor Krivenko, Joseph Kleinhenz, Guy Cohen +1
We analyze the time-dependent formation of the spectral function of an Anderson impurity model in the Kondo regime within a numerically exact real-time quantum Monte Carlo framewor…
: Implementation of the Stochastic Optimization Method for Analytic Continuation
Igor Krivenko, Malte Harland
We present the analytic continuation package, an efficient implementation of the Stochastic Optimization Method proposed by A. Mishchenko et al [Phys.…
Quantum spin fluctuations and evolution of electronic structure in cuprates
E. A. Stepanov, L. Peters, I. S. Krivenko +3
Correlation effects in CuO layers give rise to a complicated landscape of collective excitations in high-T cuprates. Their description requires an accurate account fo…
Chebyshev polynomial representation of imaginary time response functions
Emanuel Gull, Sergei Iskakov, Igor Krivenko +2
Problems of finite-temperature quantum statistical mechanics can be formulated in terms of imaginary (Euclidean) -time Green's functions and self-energies. In the context of realis…
