Seminare

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.

High-Fidelity Hot Gates for Generic Spin-Resonator Systems (Dr. M. Schütz)

We propose and analyze a high-fidelity hot gate for generic spin-resonator systems which allows for coherent spin-spin coupling, in the presence of a thermally populated resonator mode. [mehr]

Decoding Protocols for Classical Communication on Quantum Channels (M. Rosati)

I discuss the transmission of classical information via quantum carriers with focus on the decoding stage. [mehr]

DMRG with Subspace Expansion on Symmetry-Protected Tensor Networks (C. Hubig)

The Density Matrix Renormalisation Group when applied to matrix-product states is the method of choice for ground-state search on one-dimensional systems and still highly competitive even in unfavourable circumstances, such as critical systems and higher dimensions. [mehr]

Efficient representation of fully many-body localized systems using tensor networks (Dr. T. Wahl)

Many-body localization (MBL) is currently an intensely studied topic and characterized by the fact that certain strongly disordered systems fail to thermalize. For sufficiently strong disorder in one dimension, all eigenstates of MBL systems fulfill the area law of entanglement. [mehr]

Majorana quasi-particles from angular momentum conservation (Dr. F. Iemini)

We show how angular momentum conservation can stabilise a quasi-topological phase of matter supporting Majorana qausi-particles as edge modes. [mehr]
