Probing quasiperiodic spectral accessibility with a finite-rate quantum Otto cycle
Shujie Cheng, Lucas C. Céleri, Norton G. de Almeida +2
Quasiperiodic systems combine sharply different spectral and localisation regimes with a dense hierarchy of dynamical time scales. We show that a finite-rate quantum Otto cycle can…
The Apparatus Strikes Back: Momentum Conservation and the Cost of Spatial Superpositions
Lucas C. Céleri, Diogo O. Soares-Pinto, Daniel A. Turolla Vanzella
Preparing massive particles in coherent spatial superpositions is a central objective of modern quantum science, motivated by applications ranging from fundamental tests of quantum…
Gauge-invariant thermodynamics of a finite-time quantum Otto engine
Midana Baial Sambú, Thiago R. de Oliveira, Lucas C. Céleri
We investigate a finite-time quantum Otto engine within the framework of gauge-invariant quantum thermodynamics, using the Lipkin-Meshkov-Glick model as the working medium. In this…
Quantum state texture of dynamical criticality
Lucas C. Céleri, Krissia Zawadzki, Ivan Medina +1
We investigate the role of quantum state texture in dynamical quantum phase transitions by establishing a direct connection between critical nonequilibrium dynamics and the recentl…
Every Little Thing Heat Does Is Magic
Rafael A. Macêdo, A. de Oliveira Junior, Naim E. Comar +4
How can one certify that an unknown quantum state possesses magic without resorting to full state tomography? We address this question by introducing two thermodynamic witnesses th…
Using spatiotemporal Born rule for testing macroscopic realism: some applications to the pseudo-density matrices and nonclassical temporal correlations
Naim Elias Comar, Lucas C. Céleri, Mia Stamatova +3
We show that, given an evolving quantum system and the quasiprobability distribution generated by the spatiotemporal generalization of the Born rule in pseudo density-matrices (PDM…
Gravitational decoherence of a composite particle: the interplay between gravitons and a classical Newtonian potential
Thiago H. Moreira, Lucas Chibebe Céleri
The fact that gravitational environments cannot be shielded (since gravity is universal) makes them of great theoretical interest to decoherence mechanisms and to the quantum-to-cl…
Geometry of restricted information: the case of quantum thermodynamics
Tiago Pernambuco, Lucas Chibebe Céleri
We formulate a geometric framework in which physical laws emerge from restricted access to microscopic information. Measurement constraints are modeled as a gauge symmetry acting o…
