Quench Dynamics and Orthogonality Catastrophe of Bose Polarons
S. I. Mistakidis, G. C. Katsimiga, G. M. Koutentakis +2
We monitor the correlated quench induced dynamical dressing of a spinor impurity repulsively interacting with a Bose-Einstein condensate. Inspecting the temporal evolution of the s…
Optimal conditions for spatial adiabatic passage of a Bose-Einstein condensate
Juan Luis Rubio, Verònica Ahufinger, Thomas Busch +1
We investigate spatial adiabatic passage of a Bose-Einstein condensate in a triple well potential within the three-mode approximation. By rewriting the dynamics in the so-called ti…
Spontaneous emission of a sodium Rydberg atom close to an optical nanofibre
E Stourm, Y Zhang, M Lepers +5
We report on numerical calculations of the spontaneous emission rate of a Rydberg-excited sodium atom in the vicinity of an optical nanofibre. In particular, we study how this rate…
Switching quantum reference frames in the N-body problem and the absence of global relational perspectives
Augustin Vanrietvelde, Philipp A. Hoehn, Flaminia Giacomini
Given the importance of quantum reference frames (QRFs) to both quantum and gravitational physics, it is pertinent to develop a systematic method for switching between the descript…
Force of light on a two-level atom near an ultrathin optical fiber
Fam Le Kien, D F Kornovan, S Sahar S Hejazi +4
We study the force of light on a two-level atom near an ultrathin optical fiber using the mode function method and the Green tensor technique. We show that the total force consists…
Adiabatic preparation of squeezed states of oscillators and large spin systems coupled to a two-level system
Jiabao Chen, Denis Konstantinov, Klaus Mølmer
We study a single two-level system coupled resonantly to an oscillator mode or a large spin. By adiabatically turning on a linear driving term on the oscillator or the spin, the ei…
Entanglement in spatial adiabatic processes for interacting atoms
Albert Benseny, Irina Reshodko, Thomas Busch
We study the dynamics of the non-classical correlations for few atom systems in the presence of strong interactions for a number of recently developed adiabatic state preparation p…
Properties of the (Un)Complexity of Subsystems
Henry Stoltenberg
I investigate some properties of proposed definitions for subsystem/mixed state complexity and uncomplexity. A very strong dependence arises on the density matrix's degeneracy whic…
Topological states in the Kronig-Penney model with arbitrary scattering potentials
Irina Reshodko, Albert Benseny, Judit Romhányi +1
We use an exact solution to the fundamental finite Kronig-Penney model with arbitrary positions and strengths of scattering sites to show that this iconic model can possess topolog…
Fast control of interactions in an ultracold two atom system: Managing correlations and irreversibility
Thomás Fogarty, Lewis Ruks, Jing Li +1
We design and explore a shortcut to adiabaticity (STA) for changing the interaction strength between two ultracold, harmonically trapped bosons. Starting from initially uncorrelate…
The impact of classical control electronics on qubit fidelity
Jeroen P. G. van Dijk, Erika Kawakami, Raymond N. Schouten +5
Quantum processors rely on classical electronic controllers to manipulate and read out the quantum state. As the performance of the quantum processor improves, non-idealities in th…
Chiral force of guided light on an atom
Fam Le Kien, S. Sahar S. Hejazi, Viet Giang Truong +2
We calculate the force of a near-resonant guided light field of an ultrathin optical fiber on a two-level atom. We show that, if the atomic dipole rotates in the meridional plane,…
Loop-gap Microwave Resonator for Hybrid Quantum Systems
Jason Ball, Yu Yamashiro, Hitoshi Sumiya +5
We designed a loop-gap microwave resonator for applications of spin-based hybrid quantum systems, and tested it with impurity spins in diamond. Strong coupling with ensembles of ni…
