First Law of Quantum Thermodynamics in a Driven Open Two-Level System
Adrián Juan-Delgado, Aurélia Chenu
Assigning the variations of internal energy into heat or work contributions is a challenging task due to the fact that these properties are trajectory dependent. A number of propos…
Thermofield dynamics: Quantum Chaos versus Decoherence
Zhenyu Xu, Aurelia Chenu, Tomaž Prosen +1
Quantum chaos imposes universal spectral signatures that govern the thermofield dynamics of a many-body system in isolation. The fidelity between the initial and time-evolving ther…
Superadiabatic thermalization of a quantum oscillator by engineered dephasing
L. Dupays, I. L. Egusquiza, A. del Campo +1
Fast nonadiabatic control protocols known as shortcuts to adiabaticity have found a plethora of applications, but their use has been severely limited to speeding up the dynamics of…
Shortcuts to Adiabaticity in Driven Open Quantum Systems: Balanced Gain and Loss and Non-Markovian Evolution
S. Alipour, A Chenu, A. T. Rezakhani +1
A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driv…
Two-level System coupled to Phonons: Full Analytical Solution
Aurélia Chenu, Shiue-Yuan Shiau, Monique Combescot
We propose an analytical procedure to fully solve a two-level system coupled to phonons. Instead of using the common formulation in terms of linear and quadratic system-phonon coup…
Extreme Decoherence and Quantum Chaos
Zhenyu Xu, Luis Pedro García-Pintos, Aurélia Chenu +1
We study the ultimate limits to the decoherence rate associated with dephasing processes. Fluctuating chaotic quantum systems are shown to exhibit extreme decoherence, with a rate…
