2019-05-05 | Dipole coupling of a tunable hole double quantum dot in germanium hut wire to a microwave resonator | The germanium (Ge) hut wire system has strong spin-orbit coupling, a long
coherence time due to a very large heavy-light hole splitting, and the
advantage of site-controlled large-scale hut wire positioning. These properties
make the Ge hut wire a promising candidate for the realization of strong
coupling of spin to su... | 1905.01586v2 |
2020-06-15 | Derivative couplings in gravitational production in the early universe | Gravitational particle production in the early universe is due to the

2019-06-03 | Dispersive readout of a weakly coupled qubit via the parity-time-symmetric phase transition | For some cavity-quantum-electrodynamics systems, such as a single electron
spin coupled to a passive cavity, it is challenging to reach the
strong-coupling regime. In such a weak-coupling regime, the conventional
dispersive readout technique cannot be used to resolve the quantum states of
the spin. Here we propose an i... | 1906.00765v1 |

safe parallel i... | 2008.12662v4 |
2020-10-11 | Measurement of Higgs-boson self-coupling with single-Higgs and double-Higgs production channels | The trilinear self-coupling can be measured directly using the
Higgs-boson-pair production cross section, or indirectly through the

2020-11-18 | How important are the residual nonadiabatic couplings for an accurate simulation of nonadiabatic quantum dynamics in a quasidiabatic representation? | Diabatization of the molecular Hamiltonian is a standard approach to removing
the singularities of nonadiabatic couplings at conical intersections of
adiabatic potential energy surfaces. In general, it is impossible to eliminate
