Unravelling quantum chaos using persistent homology
Harvey Cao, Daniel Leykam, Dimitris G. Angelakis
Topological data analysis is a powerful framework for extracting useful topological information from complex datasets. Recent work has shown its application for the dynamical analy…
Pseudospin-2 in photonic chiral borophene
Philip Menz, Haissam Hanafi, Daniel Leykam +2
Pseudospin is an angular momentum degree of freedom introduced in analogy to the real electron spin in the effective massless Dirac-like equation used to describe wave evolution at…
Computing Electronic Correlation Energies using Linear Depth Quantum Circuits
Chong Hian Chee, Adrian M. Mak, Daniel Leykam +2
Efficient computation of molecular energies is an exciting application of quantum computing for quantum chemistry, but current noisy intermediate-scale quantum (NISQ) devices can o…
Photonic quantum Hall effects
Daniel Leykam, Daria Smirnova
This article reviews the development of photonic analogues of quantum Hall effects, which have given rise to broad interest in topological phenomena in photonic systems over the pa…
Topological data analysis and machine learning
Daniel Leykam, Dimitris G. Angelakis
Topological data analysis refers to approaches for systematically and reliably computing abstract ``shapes'' of complex data sets. There are various applications of topological dat…
Boosting Topological Zero Modes Using Elastomer Waveguide Arrays
Angelina Frank, Daniel Leykam, Daria A. Smirnova +2
We employ the Su-Schrieffer-Heeger model in elastic polymer waveguide arrays to design and realize travelling topologically protected modes. The observed delocalization of the opti…
Persistent homology analysis of a generalized Aubry-André-Harper model
Yu He, Shiqi Xia, Dimitris G. Angelakis +3
Observing critical phases in lattice models is challenging due to the need to analyze the finite time or size scaling of observables. We study how the computational topology techni…
Anomalous single-mode lasing induced by nonlinearity and the non-Hermitian skin effect
B. F. Zhu, Q. Wang, D. Leykam +3
Single-mode operation is a desirable but elusive property for lasers operating at high pump powers. Typically, single-mode lasing is attainable close to threshold, but increasing t…
