First and second quantized digital quantum simulations of bosonic systems
Mathias Mikkelsen, Hubert Okadome Valencia
We compare the basic resource requirements for first and second quantized bosonic mappings in a system consisting of particles in modes. In addition to the standard binary…
Entanglement-enhanced correlation propagation in the one-dimensional SU() Fermi-Hubbard model
Mathias Mikkelsen, Ippei Danshita
We investigate the dynamics of correlation propagation in the one-dimensional Fermi-Hubbard model with SU() symmetry when the repulsive-interaction strength is quenched from a l…
Quantum-selected configuration interaction with time-evolved state
Mathias Mikkelsen, Yuya O. Nakagawa
Quantum-selected configuration interaction (QSCI) utilizes an input quantum state on a quantum device to select important bases (electron configurations in quantum chemistry) that…
Relation between the noise correlations and the spin structure factor for Mott-insulating states in SU Hubbard models
Mathias Mikkelsen, Ippei Danshita
It is well established that the noise correlations measured by time-of-flight imaging in cold-atom experiments, which correspond to the density-density correlations in the momentum…
Quantum chaos in interacting Bose-Bose mixtures
Tran Duong Anh-Tai, Mathias Mikkelsen, Thomas Busch +1
The appearance of chaotic quantum dynamics significantly depends on the symmetry properties of the system, and in cold atomic systems many of these can be experimentally controlled…
Threshold photoproduction of neutral pions off protons in nuclear model with explicit mesons
D. V. Fedorov, M. Mikkelsen
We apply the nuclear model with explicit mesons to photoproduction of neutral pions off protons at the threshold. In this model the nucleons do not interact with each other via a p…
Resonant superfluidity in the Rabi-coupled spin-dependent Fermi-Hubbard model
Mathias Mikkelsen, Ryui Kaneko, Daichi Kagamihara +1
We investigate the ground-state phase diagram of the one-dimensional attractive Fermi-Hubbard model with spin-dependent hoppings and an on-site Rabi coupling using the density matr…
Static and dynamic phases of a Tonks-Girardeau gas in an optical lattice
Mathias Mikkelsen, Thomás Fogarty, Thomas Busch
We investigate the properties of a Tonks-Girardeau gas in the presence of a one-dimensional lattice potential. Such a system is known to exhibit a pinning transition when the latti…
Universal three-body physics in ultracold KRb mixtures
L. J. Wacker, N. B. Jørgensen, D. Birkmose +5
Ultracold atomic gases have recently become a driving force in few-body physics due to the observation of the Efimov effect. While initially observed in equal mass systems, one exp…
Analytic expression for three-body recombination rates into deep dimers
D. V. Fedorov, M. Mikkelsen, A. S. Jensen +1
We investigate three-body recombination rates into deep dimers in cold atomic gases with large scattering length within hyper-spherical adiabatic zero-range approach. We derive clo…
Three-body recombination of two-component cold atomic gases into deep dimers in an optical model
M. Mikkelsen, A. S. Jensen, D. V. Fedorov +1
We consider three-body recombination into deep dimers in a mass-imbalanced two-component atomic gas. We use an optical model where a phenomenological imaginary potential is added t…
