Violations of Hyperscaling in Finite-Size Scaling above the Upper Critical Dimension [PDF]
EntropyWe consider how finite-size scaling (FSS) is modified above the upper critical dimension, du=4, due to hyperscaling violations, which in turn arise from a dangerous irrelevant variable.

Refined finite-size analysis of binary-modulation continuous-variable quantum key distribution [PDF]
Quantum, 2023 Recent studies showed the finite-size security of binary-modulation CV-QKD protocols against general attacks. However, they gave poor key-rate scaling against transmission distance.

Critical quantum thermometry and its feasibility in spin systems [PDF]
Quantum, 2022 In this work, we study temperature sensing with finite-sized strongly correlated systems exhibiting quantum phase transitions. We use the quantum Fisher information (QFI) approach to quantify the sensitivity in the temperature estimation, and apply a ...

Box scaling as a proxy of finite size correlations
Scientific Reports, 2021 The scaling of correlations as a function of size provides important hints to understand critical phenomena on a variety of systems. Its study in biological structures offers two challenges: usually they are not of infinite size, and, in the majority of ...

Finite-size scaling of the photon-blockade breakdown dissipative quantum phase transition [PDF]
Quantum, 2019 We prove that the observable telegraph signal accompanying the bistability in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings model is the finite-size precursor of what in the thermodynamic limit is a genuine first-order ...

Finite‐Size Scaling for the Permeability of Discrete Fracture Networks
Geophysical Research Letters, 2023 We formulate a finite‐size scaling hypothesis to predict the global permeability of fracture networks. To validate the hypothesis, numerous discrete fracture networks are generated, and the permeability is numerically calculated. Results suggest that the

Hydrodynamic finite-size scaling of the thermal conductivity in glasses
npj Computational Materials, 2023 In the past few years, the theory of thermal transport in amorphous solids has been substantially extended beyond the Allen-Feldman model. The resulting formulation, based on the Green-Kubo linear response or the Wigner-transport equation, bridges this ...

Anisotropic scaling of the two-dimensional Ising model I: the torus
SciPost Physics, 2019 We present detailed calculations for the partition function and the free energy of the finite two-dimensional square lattice Ising model with periodic and antiperiodic boundary conditions, variable aspect ratio, and anisotropic couplings, as well as ...

Relaxation dynamics of the toric code in contact with a thermal reservoir: Finite-size scaling in a low temperature regime [PDF]
, 2014 We present an analysis of the relaxation dynamics of finite-size topological qubits in contact with a thermal bath. Using a continuous-time Monte Carlo method, we explicitly compute the low-temperature nonequilibrium dynamics of the toric code on finite ...
