Simulating Lindbladian evolution with non-abelian symmetries: Ballistic front propagation in the Hubbard model with a localized loss
Cătălin Paşcu Moca, Miklós Antal Werner, Örs Legeza +3
We develop a non-Abelian time evolving block decimation (NA-TEBD) approach to study of open systems governed by Lindbladian time evolution, while exploiting an arbitrary number of…
Towards large-scale restricted active space calculations inspired by the Schmidt decomposition
Gergely Barcza, Miklós Antal Werner, Gergely Zaránd +4
We present an alternative, memory-efficient, Schmidt decomposition-based description of the inherently bipartite restricted active space (RAS) scheme, which can be implemented effo…
Bloch oscillations and the lack of the decay of the false vacuum in a one-dimensional quantum spin chain
O. Pomponio, M. A. Werner, G. Zarand +1
We consider the decay of the false vacuum, realised within a quantum quench into an anti-confining regime of the Ising spin chain with a magnetic field opposite to the initial magn…
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…
