Coherent Contributions to Population Dynamics in a Semiconductor Microcavity
J. Paul, H. Rose, E. Swagel +3
Multidimensional coherent spectroscopy (MDCS) is used to separate coherent and incoherent many-body contributions to the population-time dynamics in a GaAs-based semiconductor micr…
Estimating disorder and its adverse effects in semiconductor Majorana nanowires
Seongjin Ahn, Haining Pan, Benjamin Woods +2
We use the available transport measurements in the literature to develop a dataset for the likely amount of disorder in semiconductor (InAs and InSb) materials which are used in fa…
Delocalized states in three-terminal superconductor-semiconductor nanowire devices
P. Yu, B. D. Woods, J. Chen +4
We fabricate three-terminal hybrid devices with a nanowire segment proximitized by a superconductor, and with two tunnel probe contacts on either side of that segment. We perform s…
Enhanced topological superconductivity in spatially modulated planar Josephson junctions
Purna P. Paudel, Trey Cole, Benjamin D. Woods +1
We propose a semiconductor-superconductor hybrid device for realizing topological superconductivity and Majorana zero modes consisting of a planar Josephson junction structure with…
Partially-separated Majorana modes in a disordered medium
Chuanchang Zeng, Gargee Sharma, Sumanta Tewari +1
Focusing on the implications of recent experiments on Majorana zero modes in semiconductor-superconductor (SM-SC) heterostructures, we critically examine the quantization of the ze…
Charge impurity effects in hybrid Majorana nanowires
Benjamin D. Woods, Sankar Das Sarma, Tudor D. Stanescu
We address an outstanding problem that represents a critical roadblock in the development of the Majorana-based topological qubit using semiconductor-superconductor hybrid structur…
