Emulation of Self-Consistent Non-Hermitian Quantum Formalisms
Mario Gonzalez, Karin Sim, R. Chitra
Standard quantum mechanics predicts the non-conservation of state norms and probability when the fundamental requirement of the Hermiticity of the Hamiltonian is relaxed. Biorthogo…
Observables in non-Hermitian systems: A methodological comparison
Karin Sim, Nicolò Defenu, Paolo Molignini +1
Despite acute interest in the dynamics of non-Hermitian systems, there is a lack of consensus in the mathematical formulation of non-Hermitian quantum mechanics in the community. D…
Quantum Metric Unveils Defect Freezing in Non-Hermitian Systems
Karin Sim, Nicolò Defenu, Paolo Molignini +1
Non-Hermiticity in quantum Hamiltonians leads to nonunitary time evolution and possibly complex energy eigenvalues, which can lead to a rich phenomenology with no Hermitian counter…
Quench dynamics and scaling laws in topological nodal loop semimetals
Karin Sim, R. Chitra, Paolo Molignini
We employ quench dynamics as an effective tool to probe different universality classes of topological phase transitions. Specifically, we study a model encompassing both Dirac-like…
