Valley-controlled chiral magnetism in transition metal dichalcogenide monolayers
Igor S. Krivenko, Vladimir N. Mantsevich, Dmitry S. Smirnov
We put forward the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in transition metal dichalcogenide monolayers as a tool to create and control a chiral magnetic texture. We show…
Proximity effects of chiral magnetization on transition metal dichalcogenides monolayers
Vladimir N. Mantsevich, Igor S. Krivenko, Dmitry S. Smirnov
We consider the proximity effects of a commensurate chiral Néel magnetic structure on the transport and optical properties of a transition metal dichalcogenide monola…
Inchworm quasi Monte Carlo for quantum impurities
Hugo U. R. Strand, Joseph Kleinhenz, Igor Krivenko
The inchworm expansion is a promising approach to solving strongly correlated quantum impurity models due to its reduction of the sign problem in real and imaginary time. However,…
libcommute/pycommute: A quantum operator algebra domain-specific language and exact diagonalization toolkit
Igor Krivenko
I present libcommute, a C++11/14/17 template library that implements a domain-specific language for easy manipulating of polynomial operators used in the quantum many-body theory,…
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…
Dynamic Control of Nonequilibrium Metal-Insulator Transitions
Joseph Kleinhenz, Igor Krivenko, Guy Cohen +1
We demonstrate a first order metal-insulator phase transition in the repulsive, fully frustrated, single-band Hubbard model as a function of the coupling to a fermion bath. Time de…
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…

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…
