Shortcuts to adiabaticity using flow fields

New Journal of Physics, 2017
A shortcut to adiabaticity is a recipe for generating adiabatic evolution at an arbitrary pace. Shortcuts have been developed for quantum, classical and (most recently) stochastic dynamics. A shortcut might involve a counterdiabatic (CD) Hamiltonian that

Note on cond-mat/0510119: Jarzynski equation for adiabatically stretched rotor [PDF]

arXiv, 2005
In a recent article (cond-mat/0510119) it has been argued that the Jarzynski equation is violated for adiabatic stretching processes of a three dimensional rotor system. Here we want to show that the reasoning is not correct. Rather, the Jarzynski equation is fulfilled for this adiabatically stretched rotor.

Adiabatic noise-induced escape rate for nonequilibrium open systems

, 1999
We consider the motion of an overdamped particle in a force field in presence of an external, adiabatic noise, without the restriction that the noise process is Gaussian or the stochastic process is Markovian.

Stable Pincer Gold(III)‐TADF Emitters with Extended Donor–Acceptor Separation for Efficient Vacuum‐Deposited OLEDs with Operational Lifetime (LT95) up to 3831 h at 1000 cd m−2

Advanced Science, EarlyView.
Novel pincer gold(III)‐TADF (thermally activated delayed fluorescence) emitters with extended π‐distances exhibit small singlet‐triplet energy gaps (ΔEST), efficient reverse intersystem crossing (RISC), enhanced radiative decay rates and improved excitons utilization, leading to efficient electroluminescence.

Adiabaticity of the ramping process of an ac dipole [PDF]

Physical Review Special Topics - Accelerators and Beams, 2005
ac dipoles in accelerators are used to excite coherent betatron oscillations at a drive frequency close to the tune. If the excitation amplitude is slowly increased to the desired value and slowly decreased back to zero there is no significant emittance growth.

Using Dopants as Agents to Probe Key Electronic Properties of Organic Semiconductors

Advanced Electronic Materials, EarlyView.
Dopants are typically used in organic electronics to enhance conductivity, but here their potential is demonstrated as probes for fundamental material properties. By integrating experimental data and multiscale simulations, it is shown how dopant ionization and conductivity measurements enable accurate extraction of ionization potential and Coulomb ...

The experimental realization of high-fidelity ‘shortcut-to-adiabaticity’ quantum gates in a superconducting Xmon qubit

New Journal of Physics, 2018
Based on a ‘shortcut-to-adiabaticity’ (STA) scheme, we theoretically design and experimentally realize a set of high-fidelity single-qubit quantum gates in a superconducting Xmon qubit system.

Universal Approach to Quantum Adiabaticity via Ancilla Cavity [PDF]

arXiv, 2018
A central challenge in the successful implementation of adiabatic quantum algorithms is to maintain the quantum adiabaticity during the entire evolution. However, the energy gap between the ground and the excited states of interacting many-body systems often decreases quickly with the number of qubits, and the quantum adiabaticity can be severely ...
