Local Hamiltonians for one-dimensional critical models
Dillip K. Nandy, N. S. Srivatsa, Anne E. B. Nielsen
Conformal field theory has turned out to be a powerful tool to derive interesting lattice models with analytical ground states. Here, we investigate a class of critical, one-dimens…
Quantum and Nonlinear Optics in Strongly Interacting Atomic Ensembles
Callum R. Murray, Thomas Pohl
Coupling light to ensembles of strongly interacting particles has emerged as a promising route toward achieving few photon nonlinearities. One specific way to implement this kind o…
Probing and characterizing the growth of a crystal of ultracold bosons and light
Stefan Ostermann, Francesco Piazza, Helmut Ritsch
The non-linear coupled particle light dynamics of an ultracold gas in the field of two independent counter-propagating laser beams can lead to the dynamical formation of a self-ord…
Controllable quantum scars in semiconductor quantum dots
J. Keski-Rahkonen, P. J. J. Luukko, L. Kaplan +2
Quantum scars are enhancements of quantum probability density along classical periodic orbits. We study the recently discovered phenomenon of strong, perturbation-induced quantum s…
Including temperature in a wavefunction description of the dynamics of the quantum Rabi model
Michael Werther, Frank Grossmann
We present a wavefunction methodology to account for finite temperature initial conditions in the quantum Rabi model. The approach is based on the Davydov-Ansatz together with a st…
Quantum steering with positive operator valued measures
H. Chau Nguyen, Antony Milne, Thanh Vu +1
We address the problem of quantum nonlocality with positive operator valued measures (POVM) in the context of Einstein-Podolsky-Rosen quantum steering. We show that, given a candid…
