Measuring central charge on a universal quantum processor
Nazlı Uğur Köylüoğlu, Swarndeep Majumder, Mirko Amico +5
Central charge is a fundamental quantity in conformal field theories (CFT), and plays a crucial role in determining universality classes of critical points in two-dimensional syste…
Trace distance between fermionic Gaussian states from a truncation method
Jiaju Zhang, M. A. Rajabpour
In this paper, we propose a novel truncation method for determining the trace distance between two Gaussian states in fermionic systems. For two fermionic Gaussian states, characte…
Universal logarithmic correction to Rényi (Shannon) entropy in generic systems of critical quadratic fermions
Babak Tarighi, Reyhaneh Khasseh, M. N. Najafi +1
The Rényi (Shannon) entropy, i.e. , of the ground state of quantum systems in local bases normally show a volume-law behavior. For a subsystem of quantum chains at critic…
Subsystem distances between quasiparticle excited states
Jiaju Zhang, M. A. Rajabpour
We investigate the subsystem Schatten distance, trace distance and fidelity between the quasiparticle excited states of the free and the nearest-neighbor coupled fermionic and boso…
Entanglement of magnon excitations in spin chains
Jiaju Zhang, M. A. Rajabpour
We calculate exactly the entanglement content of magnon excited states in the integrable spin-1/2 XXX and XXZ chains in the scaling limit. In particular, we show that as far as the…
Exact full counting statistics for the staggered magnetization and the domain walls in the XY spin chain
Filiberto Ares, M. A. Rajabpour, Jacopo Viti
We calculate exactly cumulant generating functions (full counting statistics) for the transverse, staggered magnetization and the domain walls at zero temperature for a finite inte…
