Photonic quantum simulations of coupled -symmetric Hamiltonians
Nicola Maraviglia, Patrick Yard, Ross Wakefield +9
Parity-time () symmetric Hamiltonians are generally non-Hermitian and give rise to exotic behaviour in quantum systems at exceptional points, where eigenvectors coalesce. The r…
Connecting active and passive -symmetric Floquet modulation models
Andrew K. Harter, Yogesh N. Joglekar
Open systems with gain, loss, or both, described by non-Hermitian Hamiltonians, have been a research frontier for the past decade. In particular, such Hamiltonians which possess pa…
Real Edge Modes in a Floquet-modulated -symmetric SSH model
Andrew K. Harter, Naomichi Hatano
Non-Hermitian Hamiltonians provide a simple picture for analyzing systems with natural or induced gain and loss; however, in general, such Hamiltonians feature complex energies and…
Passive -symmetry breaking transitions without exceptional points in dissipative photonic systems
Yogesh N. Joglekar, Andrew K. Harter
Over the past decade, parity-time ()-symmetric Hamiltonians have been experimentally realized in classical, optical settings with balanced gain and loss, or in quantu…
Observation of slowly decaying eigenmodes without exceptional points in Floquet, dissipative, synthetic circuits
Roberto de J. León-Montiel, Mario A. Quiroz-Juárez, Jorge L. Domínguez-Juárez +4
We report the first experimental observation of multiple transitions showing the emergence and disappearance of slowly decaying eigenmodes in a dissipative, Floquet electronic syst…
Fragile aspects of topological transition in lossy and parity-time symmetric quantum walks
Andrew K. Harter, Avadh Saxena, Yogesh N. Joglekar
Quantum walks often provide telling insights about the structure of the system on which they are performed. In PT-symmetric and lossy dimer lattices, the topological properties of…
