All-microwave and low-cost Lamb shift engineering for a fixed frequency multi-level superconducting qubit

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Gary A. Steele, , , | Summary: It is known that the electromagnetic vacuum is responsible for the Lamb shift, which is a crucial phenomenon in quantum electrodynamics (QED). In circuit QED, the readout or bus resonators that are dispersively coupled can result in […]

Critical properties of the Majorana chain with competing interactions

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We study critical properties of a Majorana chain in the presence of two competing interactions of the shortest possible range. The obtained phase diagram is very rich and contains nine different phases, including three floating, two Ising, and four gapped […]

Single-test evaluation of directional elastic properties of anisotropic structured materials

Kavli Affiliate: Chiara Daraio | First 5 Authors: Jagannadh Boddapati, Moritz Flaschel, Siddhant Kumar, Laura De Lorenzis, Chiara Daraio | Summary: When the elastic properties of structured materials become direction-dependent, the number of their descriptors increases. For example, in two-dimensions, the anisotropic behavior of materials is described by up to 6 independent elastic stiffness parameters, […]
