Variational theory of angulons and their rotational spectroscopy
Zhongda Zeng, Enderalp Yakaboylu, Mikhail Lemeshko +2
The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations of a many-body bath, can be used to describe an impurity rotating in a fluid or solid environment.…
Dissipative dynamics of an impurity with spin-orbit coupling
Areg Ghazaryan, Alberto Cappellaro, Mikhail Lemeshko +1
Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling (SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose and interpret qu…
Topological charges of periodically kicked molecules
Volker Karle, Areg Ghazaryan, Mikhail Lemeshko
We show that the simplest of existing molecules -- closed-shell diatomics not interacting with one another -- host topological charges when driven by periodic far-off-resonant lase…
Effective model for studying optical properties of lead-halide perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
We use general symmetry-based arguments to construct an effective model suitable for studying optical properties of lead-halide perovskites. To build the model, we identify an atom…
Diagrammatic Monte Carlo for electronic correlation in molecules: high-order many-body perturbation theory with low scaling
G. Bighin, Q. P. Ho, M. Lemeshko +1
We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams, we sample th…
Spin-Electric Coupling in Lead Halide Perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
Lead-halide perovskites enjoy a number of remarkable optoelectronic properties. To explain their origin, it is necessary to study how electromagnetic fields interact with these sys…
