Controlled finite momentum pairing and spatially varying order parameter in proximitized HgTe quantum wells
Hart, Sean; Ren, Hechen; Kosowsky, Michael Steven; Ben-Shach, Gilad; Leubner, Philipp; Brune, Christopher; Buhmann, Hartmut; Molenkamp, Laurens; Halperin, Bertrand I.; Yacoby, Amir (Springer Nature, 2016)Conventional s-wave superconductivity is understood to arise from singlet pairing of electrons with opposite Fermi momenta, forming Cooper pairs whose net momentum is zero[1]. Several recent studies have focused on structures ... -
Detecting Majorana modes in one-dimensional wires by charge sensing
Ben-Shach, Gilad; Haim, Arbel; Appelbaum, Ian; Oreg, Yuval; Yacoby, Amir; Halperin, Bertrand I. (American Physical Society (APS), 2015)The electron number parity of the ground state of a semiconductor nanowire proximity coupled to a bulk superconductor can alternate between the quantized values ±1 if parameters such as the wire length L, the chemical ... -
Detecting Non-Abelian Anyons by Charging Spectroscopy
Ben-Shach, Gilad; Laumann, Chris; Neder, I.; Yacoby, Amir; Halperin, Bertrand I. (American Physical Society (APS), 2013)Observation of non-Abelian statistics for the \(e/4\) quasiparticles in the \(\nu =\frac{5}{2}\) fractional quantum Hall state remains an outstanding experimental problem. The non-Abelian statistics are linked to the ... -
Theoretical Considerations for Experiments to Create and Detect Localised Majorana Modes in Electronic Systems
Ben-Shach, Gilad (2015-01-06)This thesis presents our work on building a bridge between the theoretical proposals for the condensed matter realisation of peculiar localised excitations, known as Majorana modes, and experiments to search for them. The ...
