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…

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…

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…
