Spin-Induced Fractal Time-Crystal-Like Dynamics and Non-Markovian Memory in the Bateman Dual Oscillator
Partha Nandi, Giuseppe Vitiello
Can a closed quantum system generate time-crystal-like nonequilibrium behavior, self-similar scaling structures, and non-Markovian memory without external driving or coupling to a…
Spin-Induced Non-Markovian Time-Crystal-Like Dynamics and Fractal Scaling in the Bateman Dual Oscillator
Partha Nandi, Giuseppe Vitiello
Can a closed quantum system generate persistent time-crystal-like dynamics without external driving? Within the Bateman dual oscillator framework, we show that the answer is affirm…
Probing mixing of photons and axion-like particles by geometric phase
A. Capolupo, G. Lambiase, G. Vitiello
We find that a geometric phase characterizes the phenomenon of mixing of photons with axion-like particles (ALPs). The laboratory observation of such a phase may provide a novel to…
Noncommutative spectral geometry, dissipation and the origin of quantization
Mairi Sakellariadou, Antonio Stabile, Giuseppe Vitiello
We present a physical interpretation of the doubling of the algebra, which is the basic ingredient of the noncommutative spectral geometry, developed by Connes and collaborators as…
Quantization, group contraction and zero point energy
M. Blasone, E. Celeghini, P. Jizba +1
We study algebraic structures underlying 't Hooft's construction relating classical systems with the quantum harmonic oscillator. The role of group contraction is discussed. We pro…
Quantization of scalar fields in curved background, deformed Hopf algebra and entanglement
A. Iorio, G. Lambiase, G. Vitiello
A suitable deformation of the Hopf algebra of the creation and annihilation operators for a complex scalar field, initially quantized in Minkowski space--time, induces the canonica…
