Modified spin-wave theory with ordering vector optimization II: Spatially anisotropic triangular lattice and model with Heisenberg interactions
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We study the ground state phases of the Heisenberg quantum antiferromagnet on the spatially anisotropic triangular lattice and on the square lattice with up to next-next-ne…
Scalable Architecture for a Room Temperature Solid-State Quantum Information Processor
Norman Y. Yao, Liang Jiang, Alexey V. Gorshkov +4
The realization of a scalable quantum information processor has emerged over the past decade as one of the central challenges at the interface of fundamental science and engineerin…
Microwave guiding of electrons on a chip
Johannes Hoffrogge, Roman Fröhlich, Mark A. Kasevich +1
Electrons travelling in free space have allowed to explore fundamental physics like the wave nature of matter, the Aharonov-Bohm and the Hanbury Brown-Twiss effect. Complementarily…
Creating exotic condensates via quantum-phase-revival dynamics in engineered lattice potentials
M. Buchhold, U. Bissbort, S. Will +1
In the field of ultracold atoms in optical lattices a plethora of phenomena governed by the hopping energy and the interaction energy have been studied in recent years. How…
Trapping ions with lasers
Cecilia Cormick, Tobias Schaetz, Giovanna Morigi
This work theoretically addresses the trapping an ionized atom with a single valence electron by means of lasers, analyzing qualitatively and quantitatively the consequences of the…

We study the properties of a mobile hole in the model on the square lattice by means of variational Monte Carlo simulations based on the entangled-plaquette ansatz. Our energ…
Optomechanical coupling in a two-dimensional photonic crystal defect cavity
Emanuel Gavartin, Remy Braive, Isabelle Sagnes +4
Periodically structured materials can sustain both optical and mechanical modes. Here we investigate and observe experimentally the optomechanical properties of a conventional two-…
Entanglement distillation by dissipation and continuous quantum repeaters
Karl Gerd H. Vollbrecht, Christine A. Muschik, J. Ignacio Cirac
Even though entanglement is very vulnerable to interactions with the environment, it can be created by purely dissipative processes. Yet, the attainable degree of entanglement is p…
Coherent Interaction of a Single Fermion with a Small Bosonic Field
Sebastian Will, Thorsten Best, Simon Braun +2
We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival s…
Optomechanical sideband cooling of a micromechanical oscillator close to the quantum ground state
Remi Riviere, Samuel Deleglise, Stefan Weis +4
Cooling a mesoscopic mechanical oscillator to its quantum ground state is elementary for the preparation and control of low entropy quantum states of large scale objects. Here, we…
Controlling the quantum stereodynamics of ultracold bimolecular reactions
M. H. G. de Miranda, A. Chotia, B. Neyenhuis +6
Chemical reaction rates often depend strongly on stereodynamics, namely the orientation and movement of molecules in three-dimensional space. An ultracold molecular gas, with a tem…
