Measuring out quasi-local integrals of motion from entanglement
B. Lu, C. Bertoni, S. J. Thomson +1
Quasi-local integrals of motion are a key concept underpinning the modern understanding of many-body localisation, an intriguing phenomenon in which interactions and disorder come…
The Born-Oppenheimer Approach to the Matter-Gravity System and Unitarity
C. Bertoni, F. Finelli, G. Venturi
The Born-Oppenheimer approach to the matter-gravity system is illustrated and the unitary evolution for matter, in the absence of phenomena such as tunnelling or other instabilitie…
Local integrals of motion and the stability of many-body localisation in Wannier-Stark potentials
C. Bertoni, J. Eisert, A. Kshetrimayum +2
Many-body localisation in disordered systems in one spatial dimension is typically understood in terms of the existence of an extensive number of (quasi)-local integrals of motion…
Power Spectrum Analysis of the ESP Galaxy Redshift Survey
E. Carretti, C. Bertoni, A. Messina +2
We measure the power spectrum of the galaxy distribution in the ESO Slice Project (ESP) galaxy redshift survey. We develope a technique to describe the survey window function analy…
Semiclassical Gravity and Large Scale Structure
C. Bertoni, E. Carretti, F. Finelli +2
The possible cosmological effects of primordial fluctuation corrections to the evolution equation of matter obtained from the Wheeler--De Witt equation are explored. In particular,…
Adiabatic Invariants and Scalar Fields in a de Sitter Space-Time
C. Bertoni, F. Finelli, G. Venturi
The method of adiabatic invariants for time dependent Hamiltonians is applied to a massive scalar field in a de Sitter space-time. The scalar field ground state, its Fock space and…
