Robust Transport Signatures of Topological Superconductivity in Topological Insulator Nanowires [PDF]

Physical Review Letters, 2014
Finding a clear signature of topological superconductivity in transport experiments remains an outstanding challenge. In this work, we propose exploiting the unique properties of three-dimensional topological insulator nanowires to generate a normal-superconductor junction in the single-mode regime where an exactly quantized $2e^2/h$ zero-bias ...

Effect of topological length on bound state signatures in a topological nanowire

Physical Review B, 2023
Majorana bound states (MBS) at the end of nanowires have been proposed as one of the most important candidate for the topological qubits. However, similar tunneling conductance features for both the MBS and Andreev bound states (ABS) have turned out to be a major obstacle in the verification of the presence of MBS in semiconductor-superconductor ...

Alexander polynomials and signatures of some high-dimensional knots [PDF]

arXiv, 2022
We give necessary and sufficient conditions for an integer to be the signature of a (4q-1)-knot in the (4q+1)-sphere with a given square-free Alexander polynomial.

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer

Molecular Oncology, EarlyView.
We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

A model of quantum gravity with emergent spacetime

Journal of High Energy Physics, 2020
We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical. The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites. In the limit

Entanglement spectrum crossings reveal non-Hermitian dynamical topology

Physical Review Research, 2021
The development of non-Hermitian topological band theory has led to observations of novel topological phenomena in effectively classical, driven, and dissipative systems. However, for open quantum many-body systems, the absence of a ground state presents

Secure Application of MIoT: Privacy-Preserving Solution for Online English Education Platforms

Applied Sciences, 2023
With the increasing demand for higher-quality services, online English education platforms have gained significant attention. However, practical application of the Mobile Internet of Things (MIoT) still faces various challenges, including communication ...

Strongly invertible knots, invariant surfaces, and the Atiyah-Singer signature theorem [PDF]

arXiv, 2021
We use the G-signature theorem to define an invariant of strongly invertible knots analogous to the knot signature.

Signature for the Shape of the Universe [PDF]

Int.J.Mod.Phys. D9 (2000) 687-696, 2001
If the universe has a nontrivial shape (topology) the sky may show multiple correlated images of cosmic objects. These correlations can be couched in terms of distance correlations. We propose a statistical quantity which can be used to reveal the topological signature of any Robertson-Walker (RW) spacetime with nontrivial topology.

Signatures of topology in quantum quench dynamics and their interrelation [PDF]

Physical Review Research, 2020
Motivated by recent experimental progress in the study of quantum systems far from equilibrium, we investigate the relation between several dynamical signatures of topology in the coherent time-evolution after a quantum quench. Specifically, we study the conditions for the appearance of entanglement spectrum crossings, dynamical quantum phase ...
