An Improved Parameterization Procedure for NDDO-Descendant Semiempirical Methods
Adrian Wee Wen Ong, Steve Yueran Cao, Leong Chuan Kwek
MNDO-based semiempirical methods in quantum chemistry have found widespread application in the modelling of large and complex systems. A method for the analytic evaluation of first…
Digital Quantum Simulation of the Spin-Boson Model under Open System Dynamics
Andreas Burger, Leong Chuan Kwek, Dario Poletti
Digital quantum computers have the potential to simulate complex quantum systems. The spin-boson model is one of such systems, used in disparate physical domains. Importantly, in a…
Dicke superradiance requires interactions beyond nearest-neighbors
Wai-Keong Mok, Ana Asenjo-Garcia, Tze Chien Sum +1
Photon-mediated interactions within an excited ensemble of emitters can result in Dicke superradiance, where the emission rate is greatly enhanced, manifesting as a high-intensity…
Oscillating bound states in non-Markovian photonic lattices
Kian Hwee Lim, Wai-Keong Mok, Leong-Chuan Kwek
It is known that the superposition of two bound states in the continuum (BIC) leads to the phenomenon of an oscillating bound state, where excitations mediated by the continuum mod…
Symmetry-protected topological corner modes in a periodically driven interacting spin lattice
Kelvin Koor, Raditya Weda Bomantara, Leong Chuan Kwek
Periodic driving has the longstanding reputation for generating exotic phases of matter with no static counterparts. This work explores the interplay among periodic driving, intera…
Certifying Temporal Correlations
Harshank Shrotriya, Leong-Chuan Kwek, Kishor Bharti
Self-testing has been established as a major approach for quantum device certification based on experimental statistics under minimal assumptions. However, despite more than 20 yea…
