Abstract: The quantum battery capacity is introduced in this letter as a figure of merit that expresses the potential of a quantum system to store and supply energy. It is defined as the difference between the highest and the lowest energy that can be reached by means of the unitary evolution of the system. This function is closely connected to the ergotropy, but it does not depend on the temporary level of energy of the system. The capacity of a quantum battery can be directly linked with the entropy of the battery state, as well as with measures of coherence and entanglement.

Hyperbolic enhancement of a quantum battery [0.0]
We show how one can circumvent the problem of energy loss by proposing a quantum battery model. Namely, charging the battery quadratically with a short temporal pulse induces a hyperbolic enhancement in the stored energy. We show that when the driving is strong enough the useful work which can be extracted from the quantum battery, that is the ergotropy, is exactly equal to the stored energy.

Effect of the readout efficiency of quantum measurement on the system entanglement [44.99833362998488]
We quantify the entanglement for a particle on a 1d quantum random walk under inefficient monitoring. We find that the system's maximal mean entanglement at the measurement-induced quantum-to-classical crossover is in different ways by the measurement strength and inefficiency.

Coherence manipulation in asymmetry and thermodynamics [44.99833362998488]
In the classical regime, thermodynamic state transformations are governed by the free energy. In the quantum regime, coherence and free energy are two independent resources. We show that allowing along with a source of free energy allows us to amplify any quantum coherence present in the quantum state arbitrarily.

Thermodynamics of adiabatic quantum pumping in quantum dots [50.24983453990065]
We consider adiabatic quantum pumping through a resonant level model, a single-level quantum dot connected to two fermionic leads. We develop a self-contained thermodynamic description of this model accounting for the variation of the energy level of the dot and the tunnelling rates with the thermal baths.

Vacuum enhanced charging of a quantum battery [0.0]
We show how a purely quantum effect related to the vacuum of the electromagnetic field can enhance the charging of a quantum battery. In particular, we demonstrate how an anti-Jaynes Cummings interaction can be used to increase the stored energy of an effective two-level atom.

Measurement Induced Synthesis of Coherent Quantum Batteries [0.0]
We propose a conditional synthesis of $N$ independent two-level systems (TLS) with partial quantum coherence obtained from an environment to one coherent system. The measurement process acts here as a Maxwell demon synthesizing the coherent energy of individual TLS to one large coherent quantum battery.
