Invariant-based inverse engineering for balanced displacement of a cart-pole system
I. Lizuain, A. Tobalina, A. Rodriguez-Prieto
Adiabaticity is a key concept in physics, but its applications in mechanical and control engineering remain underexplored. Adiabatic invariants ensure robust dynamics under slow ch…
Energetically efficient, mediated mechanical system for precise control of hoisting operations
Mikel Palmero, Juan Gonzalo Muga, Ander Tobalina
We introduce a mechanical control system for energy efficient and robust hoisting crane operations. The control system efficiently translates the harmonic motion of a spring loaded…
Pulse sequence design for high field NMR with NV centers in dipolarly coupled samples
Carlos Munuera-Javaloy, Ander Tobalina, Jorge Casanova
Diamond-based quantum sensors have enabled high-resolution NMR spectroscopy at the microscale in scenarios where fast molecular motion averages out dipolar interactions among targe…

Iván Panadero, Hilario Espinós, Lucas Tsunaki +7
We model and experimentally demonstrate the full time-dependent counting statistics of photons emitted by a single nitrogen-vacancy (NV) center in diamond under non-resonant laser…
High-Resolution NMR Spectroscopy at Large Fields with Nitrogen Vacancy Centers
C. Munuera-Javaloy, A. Tobalina, J. Casanova
Ensembles of nitrogen-vacancy (NV) centers are used as sensors to detect NMR signals from micron-sized samples at room temperature. In this scenario, the regime of large magnetic f…

We inverse engineer fast rotations of a linear trap with two ions for a predetermined rotation angle and time, avoiding final excitation. Different approaches are analyzed and comp…
Invariant-based inverse engineering of time-dependent, coupled harmonic oscillators
A. Tobalina, E. Torrontegui, I. Lizuain +2
Two-dimensional systems with time-dependent controls admit a quadratic Hamiltonian modelling near potential minima. Independent, dynamical normal modes facilitate inverse Hamiltoni…

Cooling methods and particle slowers as well as accelerators are basic tools for fundamental research and applications in different fields and systems. We put forward a generic mec…

We present a control scheme for quantum systems coupled to a thermal bath. We demonstrate state-to-state control between two Gibbs states. This scheme can be used to accelerate the…

I. Lizuain, A. Tobalina, A. Rodriguez-Prieto +1
We set a shortcut-to-adiabaticity strategy to design the trolley motion in a double-pendulum bridge crane. The trajectories found guarantee payload transport without residual excit…
Vanishing efficiency of speeded-up quantum Otto engines
Ander Tobalina, Ion Lizuain, J. Gonzalo Muga
We assess the energy cost of shortcuts to adiabatic expansions or compressions of a harmonic oscillator, the power strokes of a quantum Otto engine. Difficulties to identify the co…

Energy consumption for ion transport in a segmented Paul trap
A. Tobalina, J. Alonso, J. G. Muga
There is recent interest in determining energy costs of shortcuts to adiabaticity (STA), but different definitions of "cost" have been used. We demonstrate the importance of taking…

Shortcuts to adiabaticity let a system reach the results of a slow adiabatic process in a shorter time. We propose to quantify the "energy cost" of the shortcut by the energy consu…
