Symmetries of the squeeze-driven Kerr oscillator
Francesco Iachello, Rodrigo G. Cortiñas, Francisco Pérez-Bernal +1
We study the symmetries of the static effective Hamiltonian of a driven superconducting nonlinear oscillator, the so-called squeeze-driven Kerr Hamiltonian, and discover a remarkab…
Driving superconducting qubits into chaos
Jorge Chávez-Carlos, Miguel A. Prado Reynoso, Ignacio García-Mata +4
Kerr parametric oscillators are potential building blocks for fault-tolerant quantum computers. They can stabilize Kerr-cat qubits, which offer advantages toward the encoding and m…
Quantum tunneling and level crossings in the squeeze-driven Kerr oscillator
Miguel A. Prado Reynoso, D. J. Nader, Jorge Chávez-Carlos +6
The quasi-energy spectrum recently measured in experiments with a squeeze-driven superconducting Kerr oscillator showed good agreement with the energy spectrum of its corresponding…
Spectral kissing and its dynamical consequences in the squeeze-driven Kerr oscillator
Jorge Chávez-Carlos, Talía L. M. Lezama, Rodrigo G. Cortiñas +5
Transmon qubits are the predominant element in circuit-based quantum information processing, such as existing quantum computers, due to their controllability and ease of engineerin…
Characterizing the Lipkin-Meshkov-Glick excited spectrum through the quantum coherence spectrum
Qian Wang, Francisco Pérez-Bernal
Excited-state quantum phase transitions extend the quantum phase transition concept beyond the ground state and offer insights into the complex behavior of quantum systems. In the…
Excited-State Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
Jamil Khalouf-Rivera, Juan Gamito, Francisco Pérez-Bernal +2
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclus…
Excited-State Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model I: Static Aspects
Juan Gamito, Jamil Khalouf-Rivera, J. Miguel Arias +2
The basic Lipkin-Meshkov-Glick model displays a second order ground state quantum phase transition and an excited state quantum phase transition (ESQPT). The inclusion of an anharm…
Self-averaging in many-body quantum systems out of equilibrium: Chaotic systems
Mauro Schiulaz, E. Jonathan Torres-Herrera, Francisco Pérez-Bernal +1
Despite its importance to experiments, numerical simulations, and the development of theoretical models, self-averaging in many-body quantum systems out of equilibrium remains unde…
