Simulating Condensed Matter Physics on Quantum Hardware
Ruizhe Shen, Tianqi Chen, Tommy Tai +3
Quantum hardware platforms are getting increasingly sophisticated in their ability to simulate condensed matter, including but not limited to strongly-correlated, topological, and…
Interacting non-Hermitian edge and cluster bursts on a digital quantum processor
Jin Ming Koh, Wen-Tan Xue, Tommy Tai +2
A lossy quantum system harboring the non-Hermitian skin effect can in certain conditions exhibit anomalously high loss at the boundaries of the system compared to the bulk, a pheno…
Observation of higher-order topological states on a quantum computer
Jin Ming Koh, Tommy Tai, Ching Hua Lee
Programmable quantum simulators such as superconducting quantum processors and ultracold atomic lattices represent rapidly developing emergent technology that may one day qualitati…
Topological Non-Hermitian skin effect
Rijia Lin, Tommy Tai, Mengjie Yang +2
This article reviews recent developments in the non-Hermitian skin effect (NHSE), particularly on its rich interplay with topology. The review starts off with a pedagogical introdu…
Tailoring Zero-Field Magnetic Skyrmions in Chiral Multilayers by a Duet of Interlayer Exchange Couplings
Xiaoye Chen, Tommy Tai, Hui Ru Tan +4
Magnetic skyrmions have emerged as promising elements for encoding information towards biomimetic computing applications due to their pseudoparticle nature and efficient coupling t…
Simulation of interaction-induced chiral topological dynamics on a digital quantum computer
Jin Ming Koh, Tommy Tai, Ching Hua Lee
Chiral edge states are highly sought-after as paradigmatic topological states relevant to both quantum information processing and dissipationless electron transport. Using supercon…
Zoology of non-Hermitian spectra and their graph topology
Tommy Tai, Ching Hua Lee
We uncover the very rich graph topology of generic bounded non-Hermitian spectra, distinct from the topology of conventional band invariants and complex spectral winding. The graph…
Designing non-Hermitian real spectra through electrostatics
Russell Yang, Jun Wei Tan, Tommy Tai +4
Non-hermiticity presents a vast newly opened territory that harbors new physics and applications such as lasing and sensing. However, only non-Hermitian systems with real eigenener…
Stabilizing multiple topological fermions on a quantum computer
Jin Ming Koh, Tommy Tai, Yong Han Phee +2
In classical and single-particle settings, non-trivial band topology always gives rise to robust boundary modes. For quantum many-body systems, however, multiple topological fermio…
Anisotropic non-linear optical response of nodal loop materials
Tommy Tai, Ching Hua Lee
Nodal line semimetals have lately aroused much experimental and theoretical interest, with their gap closing along unconventional trajectories in the 3D Brillouin zone. These traje…
Enhanced higher harmonic generation from nodal topology
Ching Hua Lee, Han Hoe Yap, Tommy Tai +3
Among topological materials, nodal loop semimetals (NLSMs) are arguably the most topologically sophisticated, with their valence and conduction bands intersecting along arbitrarily…
Tidal surface states as fingerprints of non-Hermitian nodal knot metals
Xiao Zhang, Guangjie Li, Yuhan Liu +3
Non-Hermitian nodal knot metals (NKMs) contains intricate complex-valued energy bands gives rise to knotted exceptional loops and new topological surface states. We introduce a for…
