In situ tuning of dynamical Coulomb blockade on Andreev bound states in hybrid nanowire devices
Shan Zhang, Zhichuan Wang, Dong Pan +14
Electron interactions in quantum devices can exhibit intriguing phenomena. One example is assembling an electronic device in series with an on-chip resistor. The quantum laws of el…
Measuring statistics-induced entanglement entropy with a Hong-Ou-Mandel interferometer
Gu Zhang, Changki Hong, Tomer Alkalay +4
Despite its ubiquity in quantum computation and quantum information, a universally applicable definition of quantum entanglement remains elusive. The challenge is further accentuat…
Theoretical proposal to obtain strong Majorana evidence from scanning tunneling spectroscopy of a vortex with a dissipative environment
Gu Zhang, Chuang Li, Geng Li +4
It is predicted that a vortex in a topological superconductor contains a Majorana zero mode (MZM). The confirmative Majorana signature, i.e., the quantized conductance, ho…
Viscous flow through a finite-width slit: Boundary conditions and dissipation
Daniil Asafov, Valentin Kachorovskii, Konstantin Tikhonov +1
We study the hydrodynamic viscous electronic transport in a two-dimensional sample separated into two semi-infinite planes by a one-dimensional infinite barrier. The semi-infinite…
Recent progress on Majorana in semiconductor-superconductor heterostructures--Engineering and detection
Zhan Cao, Shumeng Chen, Gu Zhang +1
Majorana zero modes (MZMs) are exotic excitations (in condensed matter systems) that have potential applications in topological quantum computation. Though MZMs have been predicted…
Probing electron-hole weights of an Andreev bound state by transient currents
Zhan Cao, Gu Zhang, Hao Zhang +4
Andreev bound states (ABSs) are localized quantum states that contain both electron and hole components. They ubiquitously reside in inhomogeneous superconducting systems. Followin…
Plateau regions for zero-bias peaks within 5% of the quantized conductance value
Zhaoyu Wang, Huading Song, Dong Pan +13
Probing an isolated Majorana zero mode is predicted to reveal a tunneling conductance quantized at at zero temperature. Experimentally, a zero-bias peak (ZBP) is expected…
Large Andreev bound state zero bias peaks in a weakly dissipative environment
Zhichuan Wang, Shan Zhang, Dong Pan +14
We study Andreev bound states in hybrid InAs-Al nanowire devices. The energy of these states can be tuned to zero by gate voltage or magnetic field, revealing large zero bias peaks…
Double Fu-teleportation and anomalous Coulomb blockade in a Majorana-hosted superconducting island
Yiru Hao, Gu Zhang, Donghao Liu +1
We study the temperature dependence of Coulomb Blockade peak conductance based on a Majorana-hosted superconducting island. In the low-temperature regime, we discover a coherent do…
