Quasiparticle spectra of supersolid lattice gases at near-resonant Rydberg-dressing
Andreas Geißler, Ulf Bissbort, Walter Hofstetter
One of the major challenges in realizing a strongly interacting lattice gas using Rydberg states is the occurrence of avalanche loss processes. As these are directly proportional t…
Oscillation and decay of particle current due to a quench and dephasing in an interacting fermionic system
Kenny Choo, Ulf Bissbort, Dario Poletti
We study the response of a particle current to dissipative dephasing in an interacting, few-body fermionic lattice system. The particles are prepared in the ground state in presenc…
Selective decoupling and Hamiltonian engineering in dipolar spin networks
Ashok Ajoy, Ulf Bissbort, Dario Poletti +1
We present a protocol to selectively decouple, recouple, and engineer effective couplings in mesoscopic dipolar spin networks. In particular, we develop a versatile protocol that r…
Converting heat into directed transport on a tilted lattice
Colin Teo, Ulf Bissbort, Dario Poletti
We present a self-contained engine, which is made of one or more two-level systems, each of which is coupled to a single bath, as well as to a common load composed of a particle on…
Minimal motor for powering particle motion from spin imbalance
Ulf Bissbort, Colin Teo, Chu Guo +3
We introduce a minimalistic quantum motor for coupled energy and particle transport. The system is composed of two spins, each coupled to a different bath and to a particle which c…
Operator-based derivation of phonon modes and characterization of correlations for trapped ions at zero and finite temperature
Ulf Bissbort, Walter Hofstetter, Dario Poletti
We present a self-contained operator-based approach to derive the spectrum of trapped ions. This approach provides the complete normal form of the low energy quadratic Hamiltonian…
