In unregelmäßigen Abständen finden am MPQ Seminare statt. Diese werden von den Wissenschaftlern der einzelnen Abteilungen organisiert.
Der Veranstaltungsort wird mit dem jeweiligen Seminar bekannt gegeben.
In two dimensions, Projected Entangled-Pair States (PEPS) are elegant many-body wavefunctions which capture efficiently the quantum entanglement of ground states of local quantum spin Hamiltonians.

Trapped ions are a promising candidate system to realize a scalable quantum computer. We present a modular quantum computing architecture comprised of a chain of 171Yb+ ions with individual Raman beam addressing and individual readout.

Recently we have predicted a new quasiparticle - the angulon - which is formed when a quantum impurity (such as an electron, atom, or molecule) exchanges its orbital angular momentum with a many-particle environment (such as lattice phonons or a Fermi sea).

In this presentation I will focus on discussing the interplay of Coulomb interactions and weak disorder in atomically thin two-dimensional semiconductors.
