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.
Gastgeber: MPQ, Theory Division
If a polarization excess is injected in many-spin quantum system which is initially in a high-temperature equilibrium, then this “excitation” would spread all over as consequence of spin-spin interactions. [mehr]
Quantum correlations are strongly enhanced near quantum critical points, which opens attractive prospects for applications such as quantum-enhanced metrology. [mehr]
“We propose to use Quantum Hall edge channels in order to generate long-range entanglement between spatially separated spin qubits. Since the entanglement is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.” [mehr]
A 3-mode optomechanical system (e.g., with two electromagnetic fields coupled to a single mode of a mechanical resonator) is a key element of hybrid quantum systems. [mehr]
Several types of quantum-dot spin valves were recently realized. For such systems, we have analyzed the efficient transfer of angular momentum into the nuclear bath and the detection of nuclear-spin coherence through transport signatures. [mehr]
