Quantum spin Hall effect in III-V semiconductors at elevated temperatures: advancing topological electronics
Manuel Meyer, Jonas Baumbach, Sergey Krishtopenko +13
The quantum spin Hall effect (QSHE), a hallmark of topological insulators, enables dissipationless, spin-polarized edge transport and has been predicted in various two-dimensional…
Breathing chromium spinels: a showcase for a variety of pyrochlore Heisenberg Hamiltonians
Pratyay Ghosh, Yasir Iqbal, Tobias Müller +6
We address the long-standing problem of the microscopic origin of the richly diverse phenomena in the chromium breathing pyrochlore material family. Combining electronic structure…
Quantum paramagnetism and helimagnetic orders in the Heisenberg model on the body centered cubic lattice
Pratyay Ghosh, Tobias Müller, Francesco Parisen Toldin +5
We investigate the spin Heisenberg model on the body centered cubic lattice in the presence of ferromagnetic and antiferromagnetic nearest-neighbor , second-neighbor…
Tomonaga-Luttinger liquid in the edge channels of a quantum spin Hall insulator
R. Stühler, F. Reis, T. Müller +5
Topological quantum matter is characterized by non-trivial global invariants of the bulk which induce gapless electronic states at its boundaries. A case in point are two-dimension…
Photon-Photon Entanglement with a Single Trapped Atom
B. Weber, H. P. Specht, T. Mueller +4
An experiment is performed where a single rubidium atom trapped within a high-finesse optical cavity emits two independently triggered entangled photons. The entanglement is mediat…
