Annabelle is a finalist for the Debbie Jin Prize

It's always great news that one of our own is nominated for a major prize: in this case, Annabelle Bohrdt is a finalist for the 2022 APS Debbie Jin Prize. She will give an invited talk at the special DAMOP Thesis Prize session in Orlando, FL. We're ecstatic.

She has also won the Friedrich Hirzebruch Doctoral Prize 2022 for her dissertation "Probing strongly correlated many-body systems with quantum simulation". The prize announcement is here: https://www.studienstiftung.de/auszeichnungen/promotionspreise/preistrae....

Former (and recent) ITAMP Fellow publishes a book about “quantum steampunk”

Recent ITAMP Fellow Nicole Yunger Halpern is publishing a book for the general public about her research: Quantum Steampunk: The Physics of Yesterday’s Tomorrow, coming out in March 2022. Steampunk is an artistic and literary genre that features futuristic technologies in Victorian settings. This genre is coming to life in a growing field that combines quantum information science, which underlies cutting-edge technologies, with thermodynamics, the Victorian science of energy. Quantum Steampunk explores this intersection’s background, landscape, and opportunities.

Triangular Gross-Pitaevskii breathers and Damski-Chandrasekhar shock waves

The recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and the high-density zero-temperature triangular free-fermionic clouds, both trapped harmonically, perfectly explains the former phenomenon but leaves uninterpreted the nature of the initial (t=0) singularity. This singularity is a density discontinuity that leads, in the bosonic case, to an infinite force at the cloud edge. The map itself becomes invalid at time t=T/4. Here, we first map -- using the scale invariance of the problem -- the trapped motion to an untrapped one. Then we show that in the new representation, the solution [arXiv:2011.01415] becomes, along a ray in the direction normal to one of the three edges of the initial cloud, a freely propagating one-dimensional shock wave of a class proposed by Damski in [Phys. Rev. A 69, 043610 (2004)]. There, for a broad class of initial conditions, the one-dimensional hydrodynamic equations can be mapped to the inviscid Burgers' equation, a nonlinear transport equation. More specifically, under the Damski map, the t=0 singularity of the original problem becomes, verbatim, the initial condition for the wave catastrophe solution found by Chandrasekhar in 1943 [Ballistic Research Laboratory Report No. 423 (1943)]. At t=T/8, our interpretation ceases to exist: at this instance, all three effectively one-dimensional shock waves emanating from each of the three sides of the initial triangle collide at the origin, and the 2D-1D correspondence between the solution of [arXiv:2011.01415] and the Damski-Chandrasekhar shock wave becomes invalid.

New tools in the atom array toolbox: Dual species arrays and telecom operation

Reconfigurable arrays of neutral atoms are an exciting new platform to study quantum many-body phenomena and quantum information protocols. Their excellent coherence combined with programmable Rydberg interactions have led to intriguing observations such as quantum phase transitions, the discovery of quantum many-body scars, and the recent realization of a topological spin liquid phase.

Here, I will introduce new methods for controlling and measuring atom arrays that could open up new directions in quantum state control, quantum feedback and many-body physics. First, I will present our progress towards a dual species atomic array in which the second atomic species can be used to measure and control the primary species. This will lead to the possibility of performing quantum nondemolition measurements and new ways of engineering large, entangled states on these arrays. Furthermore, prospects of studying open systems with engineered environments will be discussed.

An alternative, hybrid approach for engineering interactions and scaling these quantum systems is the coupling of atoms to nanophotonic structures in which photons mediate interactions between atoms. Such a system can function as the building block of a large-scale quantum network. In this context, I will present quantum network node architectures that are capable of long-distance entanglement distribution at telecom wavelengths.
