  • Author(s): Nicola Mayer, Serguei Patchkovskii, Felipe Morales, Misha Ivanov, and Olga Smirnova Atoms are usually thought of as achiral objects. However, one can construct superpositions of atomic states that are chiral [1]. Here, we show how to excite such superpositions with tailored light fields both in the weak-field and strong-field regimes, using realistic laser parameters. First, we use… [Phys. Rev.

  • Author(s): Marijn P. Man, Gerrit C. Groenenboom, and Tijs Karman Ultracold molecules undergo “sticky collisions” that result in loss even for chemically nonreactive molecules. Sticking times can be enhanced by orders of magnitude by interactions that lead to nonconservation of nuclear spin or total angular momentum. We present a quantitative theory of the require… [Phys. Rev. Lett. 129, 243401] Published Tue Dec 06, 2022
  • Author(s): Keisuke Fujii, Masaru Hongo, and Tilman Enss We investigate the long-range behavior of the induced Casimir interaction between two spinless heavy impurities, or polarons, in superfluid cold atomic gases. With the help of effective field theory (EFT) of a Galilean invariant superfluid, we show that the induced impurity-impurity potential at lon… [Phys. Rev.

  • Author(s): Francesco Petiziol and André Eckardt Considering the example of superconducting circuits, we show how Floquet engineering can be combined with reservoir engineering for the controlled preparation of target states. Floquet engineering refers to the control of a quantum system by means of time-periodic forcing, typically in the high-freq… [Phys. Rev. Lett. 129, 233601] Published Wed Nov 30, 2022
  • Author(s): Xavier Barcons Planas, Andrés Ordóñez, Maciej Lewenstein, and Andrew S. Maxwell Ultrafast imaging of molecular chirality is a key step toward the dream of imaging and interpreting electronic dynamics in complex and biologically relevant molecules. Here, we propose a new ultrafast chiral phenomenon exploiting recent advances in electron optics allowing access to the orbital angu… [Phys. Rev. Lett. 129, 233201] Published Tue Nov 29...
  • Author(s): Zongping Gong, Miguel Bello, Daniel Malz, and Flore K. Kunst Both non-Hermitian systems and the behavior of emitters coupled to structured baths have been studied intensely in recent years. Here, we study the interplay of these paradigmatic settings. In a series of examples, we show that a single quantum emitter coupled to a non-Hermitian bath displays a numb… [Phys. Rev. Lett. 129, 223601] Published Wed Nov 23, 2022
  • Author(s): Yuki Miyazawa, Ryotaro Inoue, Hiroki Matsui, Gyohei Nomura, and Mikio Kozuma A Bose-Einstein condensate of europium atoms provides a new experimental platform for studying quantum spin interactions. [Phys. Rev. Lett. 129, 223401] Published Tue Nov 22, 2022
