Probing the Quantum Nature of Gravity through Classical Diffusion
Oliviero Angeli, Sandro Donadi, Giovanni Di Bartolomeo +3
The question of whether gravity is fundamentally quantum remains one of the deepest open problems in modern physics. A recently explored approach consists of testing gravity's abil…
Doppler-induced tunable and shape-preserving frequency conversion of microwave wave packets
Felix Ahrens, Enrico Bogoni, Renato Mezzena +7
In superconducting electronics, the ability to control the frequency of microwave wave packets is crucial for several applications, such as the operation of superconducting quantum…
Cryogenic pressure sensing with an ultrafast Meissner-levitated microrotor
Joel K Jose, Andrea Marchese, Marion Cromb +5
Magnetically levitated spinning rotors are key elements in important technologies such as navigation by gyroscopes, energy storage by flywheels, ultra-high vacuum generation by tur…
Synthetic-lattice Bloch wave dynamics in a single-mode microwave resonator
F. Ahrens, N. Crescini, A. Irace +8
Frequency-based synthetic dimensions are a promising avenue for expanding the dimensionality of photonic systems. In this work, we show how a tilted synthetic lattice is naturally…
Observation of gyroscopic coupling in a non-spinning levitated ferromagnet
F. Ahrens, A. Vinante
A non-spinning permanent ferromagnet is predicted to behave as a gyroscope at sufficiently low frequencies, which can be seen as a manifestation of the Einstein-de Haas effect. Thi…
Creation of a black hole bomb instability in an electromagnetic system
Marion Cromb, Maria Chiara Braidotti, Andrea Vinante +2
The amplification and generation of electromagnetic radiation by a rotating metallic or lossy cylinder, first theorized by Zeldovich in the 1970s, is tightly connected to the conce…
