Phase-Locked Quantum Battery Charging via Dissipative Mode Selection
Borhan Ahmadi, Lei Du, André H. A. Malavazi +3
We investigate how dynamical instability and reservoir engineering can be harnessed to enhance the quality of quantum-battery charging in a bosonic two-mode system. We show that re…
Unequal Coherent Ergotropy at Equal Interferometric Visibility and Energy in Quantum-Controlled Interferometers
Tonipe Anuradha, André H. A. Malavazi, Borhan Ahmadi +2
The ergotropy, or unitarily extractable work, of a quantum system naturally splits into incoherent and coherent contributions, respectively set by population inversion and coherenc…
Charging Quantum Batteries with Chiral Squeezing
Borhan Ahmadi, André H. A. Malavazi, Janine Splettstoesser +2
We propose a quantum-battery charger based on a driven bosonic Kitaev chain (BKC), where chiral squeezing converts passive input fluctuations into ordered, non-passive battery stat…
Reservoir-Engineered Low-Threshold Quantum Energy Storage
Borhan Ahmadi, André H. A. Malavazi, Paweł Mazurek +2
Fast charging of quantum batteries requires amplification of the energy transferred to a storage mode without uncontrolled gain or phenomenological non-Hermitian dynamics. Inspired…
Charge-Preserving Operations in Quantum Batteries
André H. A. Malavazi, Borhan Ahmadi, Paweł Horodecki +1
Ergotropy provides a fundamental measure of the extractable work from a quantum system and, consequently, of the maximal useful energy, or charge, stored within it. Understanding h…
Revival and instabilities of entanglement in monitoring maps with indefinite causal order
Shahana Aziz, André H. A. Malavazi, Pedro R. Dieguez
In this proceeding, we revisit the discussion presented in Ref. [Commun Phys 7, 373 (2024)], which examines the behavior of a quantum switch involving two arbitrary quantum operati…
Fluctuation theorems with optical tweezers: theory and practice
Thalyta T. Martins, André H. A. Malavazi, Lucas P. Kamizaki +4
Fluctuation theorems, such as the Jarzynski equality and the Crooks relation, are effective tools connecting non-equilibrium work statistics and equilibrium free energy differences…
Two-time weak measurement protocol for ergotropy protection in open quantum batteries
André H. A. Malavazi, Rishav Sagar, Borhan Ahmadi +1
Quantum batteries are emerging as highly efficient energy storage devices that can exceed classical performance limits. Although there have been significant advancements in control…
Quantum switch instabilities with an open control
Otavio A. D. Molitor, André H. A. Malavazi, Roberto Dobal Baldijão +3
The superposition of causal order shows promise in various quantum technologies. However, the fragility of quantum systems arising from environmental interactions, leading to dissi…
Unveiling Detuning Effects for Heat-Current Control in Quantum Thermal Devices
André H. A. Malavazi, Borhan Ahmadi, Paweł Mazurek +1
Navigating the intricacies of thermal management at the quantum scale is a challenge in the pursuit of advanced nanoscale technologies. To this extent, theoretical frameworks intro…
Benchmark of the Schmiedl-Seifert optimal protocol with reduced dissipated work and fluctuations in optical tweezers
Thalyta Tavares Martins, André H. A. Malavazi, Lucas Prado Kamizaki +4
Finite-time thermodynamic transformations generally dissipate energy, as required by the Second Law, so identifying and investigating energetically optimal processes remain relevan…
