The fate of the Kondo cloud in a superconductor
Cătălin Paşcu Moca, Ireneusz Weymann, Miklós Antal Werner +1
Magnetic impurities embedded in a metal are screened by the Kondo effect, signaled by the formation of an extended correlation cloud, the so-called Kondo or screening cloud. In a s…
Quantum Quench and Charge Oscillations in the SU(3) Hubbard Model: a Test of Time Evolving Block Decimation with general non-Abelian Symmetries
Miklós Antal Werner, Cătălin Paşcu Moca, Örs Legeza +1
We introduce the notion of non-Abelian tensors, and use them to construct a general non-Abelian time evolving block decimation (NA-TEBD) scheme that uses an arbitrary number of Abe…
Vaporization dynamics of a dissipative quantum liquid
Ádám Bácsi, Catalin Pascu Moca, Gergely Zaránd +1
We investigate the stability of a Luttinger liquid, upon suddenly coupling it to a dissipative environment. Within the Lindblad equation, the environment couples to local currents…
Magnetic noise spectroscopy as a probe of local electronic correlations in two-dimensional systems
Kartiek Agarwal, Richard Schmidt, Bertrand Halperin +4
We develop the theoretical framework for calculating magnetic noise from conducting two-dimensional (2D) materials. We describe how local measurements of this noise can directly pr…
Floquet topological phases coupled to environments and the induced photocurrent
Szabolcs Vajna, Baruch Horovitz, Balázs Dóra +1
We consider the fate of a helical edge state of a spin Hall insulator and its topological transition in presence of a circularly polarized light when coupled to various forms of en…
Generalized Gibbs ensemble and work statistics of a quenched Luttinger liquid
Balázs Dóra, Ádám Bácsi, Gergely Zaránd
We analyze the probability distribution function (PDF) of work done on a Luttinger liquid for an arbitrary finite duration interaction quench and show that it can be described in t…
Fluctuation-exchange approximation theory of the non-equilibrium singlet-triplet transition
Bertalan Horváth, Bence Lazarovits, Gergely Zaránd
As a continuation of a previous work [B. Horváth et al., Phys. Rev. B {\bf 82}, 165129 (2010)], here we extend the so-called Fluctuation Exchange Approximation (FLEX) to study the…
Non-equilibrium transport theory of the singlet-triplet transition: perturbative approach
Bertalan Horváth, Bence Lazarovits, Gergely Zaránd
We use a simple iterative perturbation theory to study the singlet-triplet (ST) transition in lateral and vertical quantum dots, modeled by the non-equilibrium two-level Anderson m…
Perturbative theory of the non-equilibrium singlet-triplet transition
B. Horvath, B. Lazarovits, G. Zarand
We study equilibrium and non-equilibrium properties of a two-level quantum dot close to the singlet-triplet transition. We treat the on-site Coulomb interaction and Hund's rule cou…
Failure of mean-field approach in out-of-equilibrium Anderson model
Bertalan Horváth, Bence Lazarovits, Olivier Sauret +1
To explore the limitations of the mean field approximation, frequently used in \textit{ab initio} molecular electronics calculations, we study an out-of-equilibrium Anderson impuri…
