A Study of Modifications to Quantum Mechanics
… as a minimum length scale. Both harmonic and anharmonic oscillators are studied in this framework with normalizable, positive energy eigenstates found in both cases. The quantum uncertainty relations and classical counterparts to these states are discussed. Creating modified quantum theories …

The (Semi-)Classical Vibrational Echo
… in time for a thermal ensemble of noninteracting anharmonic oscillators. We have interpreted the dephasing and rephasing of the vibrational echo experiment in terms of a classical picture which also identifies the classical analogs of quantum mechanical double-sided Feynman diagrams. We have …

Optimizing coherence and anharmonicity of superconducting qubit
… superconducting qubits are designed to be anharmonic oscillators, which is achieved using one or more Josephson junctions, a nonlinear superconducting element. One of the main challenges in developing quantum computers is minimizing the decoherence caused by environmental noise. Decoherence …

Nonlinear dynamics and chaos in multidimensional disordered Hamiltonian systems
… the disordered Klein-Gordon (DKG) lattice of anharmonic oscillators and the disordered discrete nonlinear Schr¨odinger (DDNLS) equation, mainly in one spatial dimension suggest that nonlinearity eventually destroys AL. This leads to an infinite diffusive spreading of initially localized wave …
