Squeezing-enhanced measurement sensitivity in a cavity optomechanical system
Hugo Kerdoncuff, Ulrich B. Hoff, Glen I. Harris +2
We determine the theoretical limits to squeezing-enhanced measurement sensitivity of mechanical motion in a cavity optomechanical system. The motion of a mechanical resonator is tr…
Generic Construction of Efficient Matrix Product Operators
C. Hubig, I. P. McCulloch, U. Schollwöck
Matrix Product Operators (MPOs) are at the heart of the second-generation Density Matrix Renormalisation Group (DMRG) algorithm formulated in Matrix Product State language. We firs…
Ultrafine Entanglement Witnessing
Farid Shahandeh, Martin Ringbauer, Juan C. Loredo +1
Entanglement witnesses are invaluable for efficient quantum entanglement certification without the need for expensive quantum state tomography. Yet, standard entanglement witnessin…
Prethermalization and Persistent Order in the Absence of a Thermal Phase Transition
Jad C. Halimeh, Valentin Zauner-Stauber, Ian P. McCulloch +3
We numerically study the dynamics after a parameter quench in the one-dimensional transverse-field Ising model with long-range interactions ( with distance ), for…
Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field
S. Greschner, M. Piraud, F. Heidrich-Meisner +3
We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting…
Dephasing-assisted Gain and Loss in Mesoscopic Quantum Systems
Clemens Müller, Thomas M. Stace
Motivated by recent experiments, we analyse the phonon-assisted steady-state gain of a microwave field driving a double quantum-dot in a resonator. We apply the results of our comp…
