Reduced density matrix and entanglement Hamiltonian for a free real scalar field on an interval
Mikhail A. Baranov
An exact result for the reduced density matrix on a finite interval for a dimensional free real scalar field in the ground state is presented. In the massless case, the Willi…
Rotons and their damping in elongated dipolar Bose-Einstein condensates
S. I. Matveenko, M. S. Bahovadinov, M. A. Baranov +1
We discuss finite temperature damping of rotons in elongated Bose-condensed dipolar gases, which are in the Thomas-Fermi regime in the tightly confined directions. The presence of…
Probing infinite many-body quantum systems with finite-size quantum simulators
Viacheslav Kuzmin, Torsten V. Zache, Christian Kokail +4
Experimental studies of synthetic quantum matter are necessarily restricted to approximate ground states prepared on finite-size quantum simulators. In general, this limits their r…
Topological phonons in arrays of ultracold dipolar particles
Marco Di Liberto, Andreas Kruckenhauser, Peter Zoller +1
The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to…
Monitoring Quantum Simulators via Quantum Non-Demolition Couplings to Atomic Clock Qubits
Denis V. Vasilyev, Andrey Grankin, Mikhail A. Baranov +2
We discuss monitoring the time evolution of an analog quantum simulator via a quantum non-demolition (QND) coupling to an auxiliary `clock' qubit. The QND variable of interest is t…
High-energy Bragg scattering measurements of a dipolar supersolid
D. Petter, A. Patscheider, G. Natale +9
We present an experimental and theoretical study of the high-energy excitation spectra of a dipolar supersolid. Using Bragg spectroscopy, we study the scattering response of the sy…
