Continuous Floquet theory in solid-state NMR

open access: yesThe Journal of Chemical Physics
This article presents the application of continuous Floquet theory in solid-state nuclear magnetic resonance (NMR). Continuous Floquet theory extends the traditional Floquet theory to non-continuous Hamiltonians, enabling the description of observable effects not fully captured by the traditional Floquet theory due to its requirement for a periodic ...

An Overview of Modeling, Stability, and Control of Flapping Robots [PDF]

open access: yesفناوری در مهندسی هوافضا, 2020
Flapping drones have been the focus of attention for various reasons, such as the ability to fly scilently at low speeds and also high maneuverability. This article describes the history of flapping robots and their importance in engineering and how to ...

Decoherence models for discrete-time quantum walks and their application to neutral atom experiments

open access: yesNew Journal of Physics, 2014
We discuss decoherence in discrete-time quantum walks in terms of a phenomenological model that distinguishes spin and spatial decoherence. We identify the dominating mechanisms that affect quantum-walk experiments realized with neutral atoms walking in ...

Using Floquet Theory in the Procedure for Investigation of the Motion Stability of a Rotor System Exhibiting Parametric and Self-Excited Vibration

open access: yesJournal of Mechanical Engineering, 2019
The computational procedure for investigation vibration stability of a flexible rotor consisting of an asymmetric shaft, one disc, and supported by ball bearings is developed in this work. Lagrange equations of the second kind were used for derivation of

Time-dependent Gutzwiller simulation of Floquet topological superconductivity

open access: yesCommunications Physics
Periodically driven systems provide a novel route to control the topology of quantum materials. In particular, Floquet theory allows an effective band description of periodically-driven systems through the Floquet Hamiltonian.

Unifying Floquet Theory of Longitudinal and Dispersive Readout

open access: yesPhysical Review Letters
We devise a Floquet theory of longitudinal and dispersive readout in circuit QED. By studying qubits coupled to cavity photons and driven at the resonance frequency of the cavity $ω_{\rm r}$, we establish a universal connection between the qubit AC Stark shift and the longitudinal and dispersive coupling to photons.

Influence of anisotropic support of tool for self-excited chatter in end-milling

open access: yesNihon Kikai Gakkai ronbunshu
In end milling, chatter vibration generated during processing becomes a problem in processing accuracy. Chatter vibration is classified into forced chatter and self-excited chatter depending on the cause of the vibration.

Walsh-Floquet theory of periodic kick drives

open access: yesPhysical Review Research
Periodic kick drives are ubiquitous in digital quantum control, computation, and simulation, and are instrumental in studies of chaos and thermalization for their efficient representation through discrete gates.

Floquet insulators and lattice fermions beyond naive time discretization

open access: yesPhysical Review Research
Periodically driven quantum systems known as Floquet insulators can host topologically protected bound states known as “π modes” that exhibit response at half the frequency of the drive. Such states can also appear in undriven lattice field theories when

Linear-response theory in Floquet systems

open access: yes
Nonequilibrium quantum physics greatly simplifies in the case of time-periodic Hamiltonians, since Floquet theory provides an analogue to Bloch's theorem in the time domain. Still, the formal properties of Floquet many-body theory remain underexplored.
