Steady states and oscillation modes of two driven dissipative oscillators with non-Hermitian coupling
Sahel Ashhab, Aakanksha Sud, Shunsuke Fukami
We analyze the dynamics of two harmonic oscillators with nonlinear, non-Hermitian coupling between them. Specifically, we consider a synthetic antiferromagnet composed of two ferro…
Entangling Power and Symmetries in the Quantum Rabi Model
Ian Low, Jens Koch, Sahel Ashhab
The paper studies how the time‑averaged entangling power can detect both explicit and hidden symmetries in the quantum Rabi model, focusing on the Jaynes‑Cummings limit and the asy…
Physically motivated decompositions of single-qutrit gates
Aryan Iliat, Mark Byrd, Sahel Ashhab +1
Although only two quantum states of a physical system are often used to encode quantum information in the form of qubits, many levels can in principle be used to obtain qudits and…
Fractional squeezing: spectra and dynamics from generalized squeezing Hamiltonian with fractional orders
Sahel Ashhab
We generalize the generalized-squeezing problem to include fractional values of the squeezing order . This approach allows us to determine the locations of critical points at wh…
Is the most random pattern random? Maximizing localization in a two-dimensional lattice with engineered disorder
Morgan Berkane, Sahel Ashhab
We investigate localization in two models: a single particle in a two-dimensional square lattice described by the tight binding Hamiltonian, and a two-dimensional square qubit latt…
Computational and physical complexity of synthesizing random multi-qudit quantum states and unitary operators
Sahel Ashhab, Bora Basyildiz
We analyze the complexity of synthesizing random states and unitary operators in a multi-qudit system in two paradigms. In one case, we consider the situation in which we manipulat…
