Attempt to find the hidden symmetry in the asymmetric quantum Rabi model
S. Ashhab
It has been observed that the asymmetric quantum Rabi model (QRM), which does not possess any obvious symmetry, exhibits energy level crossings, which are often associated with sym…
Order in the ground state of a simple cubic dipole lattice in an external field
S. Ashhab, M. Carignano, M. E. Madjet
Motivated by the presence of a lattice of rotating molecular dipoles in the high temperature phase of methylammonium lead iodide, we investigate the ground state of a simple cubic…
Spectrum of the Dicke model in a superconducting qubit-oscillator system
S. Ashhab, Y. Matsuzaki, K. Kakuyanagi +4
We calculate the transmission spectrum of a superconducting circuit realization of the Dicke model and identify spectroscopic features that can serve as signatures of the superradi…
Quantum Simulation of Resonant Transitions for Solving the Eigen-problem of an Effective Water Hamiltonian
Zhaokai Li, Xiaomei Liu, Hefeng Wang +5
It is difficult to calculate the energy levels and eigenstates of a large physical system on a classical computer because of the exponentially growing size of the Hilbert space. In…
