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…
Topological and nonlinearity-induced thermalization in a PT-symmetric split-Langevin bath
Andrew K. Harter, Donald J. Priour, Daniel Sweeney +2
Open classical systems with balanced, separated gain and loss, called PT-symmetric systems, have been extensively studied over the past decade. Here, we investigate the properties…
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…
Time invariant -product and phase locking in -symmetric lattice models
Yogesh N. Joglekar, Franck Assogba Onanga, Andrew K. Harter
Over the past decade, non-Hermitian, -symmetric Hamiltonians have been investigated as candidates for both, a fundamental, unitary, quantum theory, and open systems w…
Observation of parity-time symmetry breaking transitions in a dissipative Floquet system of ultracold atoms
Jiaming Li, Andrew K. Harter, Ji Liu +3
Open physical systems with balanced loss and gain, described by non-Hermitian parity-time () reflection symmetric Hamiltonians, exhibit a transition which could engen…
Veiled symmetry of disordered Parity-Time lattices: protected PT-threshold and the fate of localization
Andrew K. Harter, Franck A. Onanga, Yogesh N. Joglekar
Open, non-equilibrium systems with balanced gain and loss, known as parity-time ()-symmetric systems, exhibit properties that are absent in closed, isolated systems.…
Sublattice signatures of transitions in a -symmetric dimer lattice
Andrew K. Harter, Yogesh N. Joglekar
Lattice models with non-hermitian, parity and time-reversal () symmetric Hamiltonians, realized most readily in coupled optical systems, have been intensely studied i…
-breaking threshold in spatially asymmetric Aubry-Andre Harper models: hidden symmetry and topological states
Andrew K. Harter, Tony E. Lee, Yogesh N. Joglekar
Aubry-Andre Harper (AAH) lattice models, characterized by reflection-asymmetric, sinusoidally varying nearest-neighbor tunneling profile, are well-known for their topological prope…
