Typical thermalization of low-entanglement states
Christian Bertoni, Clara Wassner, Giacomo Guarnieri +1
Proving thermalization from the unitary evolution of a closed quantum system is one of the oldest questions that is still nowadays only partially resolved. Several efforts have led…
Shallow shadows: Expectation estimation using low-depth random Clifford circuits
Christian Bertoni, Jonas Haferkamp, Marcel Hinsche +3
We provide practical and powerful schemes for learning many properties of an unknown n-qubit quantum state using a sparing number of copies of the state. Specifically, we present a…
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…
Minimizing couplings in renormalization by preserving short-range mutual information
Christian Bertoni, Joseph M. Renes
The connections between renormalization in statistical mechanics and information theory are intuitively evident, but a satisfactory theoretical treatment remains elusive. Recently,…
Emergent statistical mechanics from properties of disordered random matrix product states
Jonas Haferkamp, Christian Bertoni, Ingo Roth +1
The study of generic properties of quantum states has led to an abundance of insightful results. A meaningful set of states that can be efficiently prepared in experiments are grou…
Entropic time-energy uncertainty relations: An algebraic approach
Christian Bertoni, Yuxiang Yang, Joseph M. Renes
We address entropic uncertainty relations between time and energy or, more precisely, between measurements of an observable and the displacement of the -generated evolut…
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…
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…
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…
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,…
