Some questions concerning Majorana fermions in 2D ( p + ip $\text{p}+\text{ip}$ ) Fermi superfluids

open access: yesQuantum Frontiers, 2022
Most of the discussion in the literature of the Majorana fermions (M.F.’s) believed to exist in so-called 2D p + ip $\text{p}+\text{ip}$ Fermi superfluids, and in particular of their possible application in topological quantum computing (TQC) has ...

The boundaries and twist defects of the color code and their applications to topological quantum computation [PDF]

open access: yesQuantum, 2018
The color code is both an interesting example of an exactly solved topologically ordered phase of matter and also among the most promising candidate models to realize fault-tolerant quantum computation with minimal resource overhead. The contributions of

High spin-Chern-number insulator in α-antimonene with a hidden topological phase [PDF]

open access: yes2D Materials, 2022
For a time-reversal symmetric system, the quantum spin Hall phase is assumed to be the same as the Z2 topological insulator phase in the existing literature.

Determination of topological edge quantum numbers of fractional quantum Hall phases

open access: yes, 2022
To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream ($N_d$) and upstream ($N_u$) edge modes, it is pivotal to study quantized transport both in the presence and absence of edge mode equilibration.

Stacking-dependent topological quantum states in bilayer Mn_{2}Cl_{3}Br_{3}

open access: yesPhysical Review Research, 2023
Stacking-dependent physics is emerging as a fascinating research topic for two-dimensional materials. A variety of novel properties can be achieved by layer stacking according to different modes.

Piezoelectricity and topological quantum phase transitions in two-dimensional spin-orbit coupled crystals with time-reversal symmetry [PDF]

open access: yesNature Communications, 2019
Finding new physical responses that signal topological quantum phase transitions is of both theoretical and experimental importance. Here, we demonstrate that the piezoelectric response can change discontinuously across a topological quantum phase ...

Observing Topological Invariants Using Quantum Walks in Superconducting Circuits

open access: yesPhysical Review X, 2017
The direct measurement of topological invariants in both engineered and naturally occurring quantum materials is a key step in classifying quantum phases of matter.

3D quantum Hall effect in a topological nodal-ring semimetal

open access: yesQuantum Frontiers, 2023
A quantized Hall conductance (not conductivity) in three dimensions has been searched for more than 30 years. Here we explore it in 3D topological nodal-ring semimetals, by employing a minimal model describing the essential physics.

Joint entanglement of topology and polarization enables error-protected quantum registers

open access: yesNew Journal of Physics, 2018
Linear-optical systems can implement photonic quantum walks that simulate systems with nontrivial topological properties. Here, such photonic walks are used to jointly entangle polarization and winding number.
