Abstract
We evaluate the realization of a novel geometry of a guided atom interferometer based on a high-temperature superconducting microstructure. The interferometer-type structure is obtained with a guiding potential realized by two current carrying superconducting wires in combination with a closed superconducting loop sustaining a persistent current. We present the layout and realization of our superconducting atom chip. By employing simulations, we discuss the critical parameters of the interferometer guide in particular near the splitting regions of the matter waves. Based on measurements of the relevant chip properties, we discuss the application of a compact and reliable on-chip atom interferometer.
Highlights
Superconductor technology combined with atom optical systems will allow a new generation of fundamental experiments and novel applications possibly reaching to the pairing of quantum solid-state devices with neutral atoms on the quantum mechanical level [1, 2]
We present the experimental design of a ceramic-based high-temperature superconductor (HTS) atom interferometer chip structure using a persistent current loop to overcome limitations which normal conductors face
This working temperature can be generated by using liquid nitrogen as the coolant. This is a significant technical advantage compared to non-HTS materials where the critical temperature can only be achieved with liquid helium. This means the requirements for the cryogenic setup become much less stringent by using HTSs which is an important factor in the complex experimental setup of a typical ultra-cold atom experiment
Summary
Superconductor technology combined with atom optical systems will allow a new generation of fundamental experiments and novel applications possibly reaching to the pairing of quantum solid-state devices with neutral atoms on the quantum mechanical level [1, 2]. Microstructured surface trapping and manipulation devices, so-called ‘atom chips’ [3, 4], have proven their great capability and flexibility in the field of ultra-cold atom experiments over the last few years These elements which allow the generation of steep trapping potentials use current carrying wires [5] or permanent magnetic structures [6] as well as micro-optical devices [7]. With the traditional atom chips based on metallic conductors at room temperature a symmetric closed Mach–Zehnder interferometer-type guiding structure has not been realized. We present the experimental design of a ceramic-based high-temperature superconductor (HTS) atom interferometer chip structure using a persistent current loop to overcome limitations which normal conductors face.
