Tensor networks for Lattice Gauge Theories and Atomic Quantum Simulation
E. Rico, T. Pichler, M. Dalmonte +2
We show that gauge invariant quantum link models, Abelian and non-Abelian, can be exactly described in terms of tensor networks states. Quantum link models represent an ideal bridg…
Manifestation of charged and strained graphene layers in the Raman response of graphite intercalation compounds
J. C. Chacon-Torres, L. Wirtz, T. Pichler
We present detailed multi frequency resonant Raman measurements of potassium graphite intercalation compounds (GICs). From a well controlled and consecutive in-situ intercalation a…
Observation of conduction electron spin resonance in boron doped diamond
Péter Szirmai, Gábor Fábián, János Koltai +7
We observe the electron spin resonance of conduction electrons in boron doped (6400 ppm) superconducting diamond (Tc =3.8 K). We clearly identify the benchmarks of conduction elect…
Noise-resistant optimal spin squeezing via quantum control
T. Pichler, T. Caneva, S. Montangero +2
Entangled atomic states, such as spin squeezed states, represent a promising resource for a new generation of quantum sensors and atomic clocks. We demonstrate that optimal control…
Challenging the nature of low energy plasmon excitations in CaC using electron energy-loss spectroscopy
Friedrich Roth, Andreas König, Christian Kramberger +3
The nature of low energy plasmon excitations plays an important role in understanding the low energy electronic properties and coupling mechanism of different superconducting compo…
