Over forty years of research towards the understanding of Quantum Brownian Motion -- the contributions of A. O. Caldeira
Marcus V. S. Bonança, Sebastian Deffner, Gert-Ludwig Ingold
This article presents a brief account of Amir O. Caldeira's contributions to the theory of quantum Brownian motion. Motivated by its importance, we outline the description of Brown…
Excess work in counterdiabatic driving
Lucas P. Kamizaki, Marcus V. S. Bonança
Many years have passed since the conception of the quintessential method of shortcut to adiabaticity known as counterdiabatic driving (or transitionless quantum driving). Yet, this…
Correcting noisy quantum gates with shortcuts to adiabaticity
Moallison F. Cavalcante, Bariş Çakmak, Marcus V. S. Bonança +1
Unitary quantum gates constitute the building blocks of Quantum Computing in the circuit paradigm. In this work, we engineer a locally driven two-qubit Hamiltonian whose instantane…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Emergence of states in a quantum impurity model
Moallison F. Cavalcante, Marcus V. S. Bonança, Eduardo Miranda +1
In the present work, we demonstrate the emergence of states in the long-time response of a locally perturbed many-body quantum impurity model. The emergence of the double-qubit…
Nano-welding of quantum spin- chains at minimal dissipation
Moallison F. Cavalcante, Marcus V. S. Bonança, Eduardo Miranda +1
We consider the optimal control of switching on a coupling term between two quantum many-body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junct…
Optimal finite-time processes in weakly driven overdamped Brownian motion
Pierre Nazé, Sebastian Deffner, Marcus V. S. Bonança
The complete physical understanding of the optimization of the thermodynamic work still is an important open problem in stochastic thermodynamics. We address this issue using the H…
Kibble-Zurek scaling from linear response theory
Pierre Nazé, Marcus V. S. Bonança, Sebastian Deffner
While quantum phase transitions share many characteristics with thermodynamic phase transitions, they are also markedly different as they occur at zero temperature. Hence, it is no…
Fluctuation theorem for irreversible entropy production in electrical conduction
Marcus V. S. Bonança, Sebastian Deffner
Linear, irreversible thermodynamics predicts that the entropy production rate can become negative. We demonstrate this prediction for metals under AC-driving whose conductivity is…
Negative entropy production rates in Drude-Sommerfeld metals
Marcus V. S. Bonança, Pierre Nazé, Sebastian Deffner
It is a commonly accepted creed that in typical situations the rate of entropy production is non-negative. We show that this assertion is not entirely correct if a time-dependent,…
Thermodynamic control -- an old paradigm with new applications
Sebastian Deffner, Marcus V. S. Bonança
Tremendous research efforts have been invested in exploring and designing so-called shortcuts to adiabaticity. These are finite-time processes that produce the same final states th…
Approaching Carnot efficiency at maximum power in linear response regime
Marcus V. S. Bonança
We construct an example of heat engine whose efficiency at maximum power breaks down the previously derived bounds in the linear response regime. Such example takes a classical har…
Relaxation in finite and isolated classical systems: an extension of Onsager's regression hypothesis
Marcus V. S. Bonança
In order to derive the reciprocity relations, Onsager formulated a relation between thermal equilibrium fluctuations and relaxation widely known as regression hypothesis. It is sho…
