Mobility edge of the two-dimensional Bose-Hubbard model

Physical Review Research, 2020
We analyze the disorder-driven localization of the two-dimensional Bose-Hubbard model by evaluating the full low-energy quasiparticle spectrum via a recently developed fluctuation operator expansion method.

Phase transitions above the upper critical dimension

SciPost Physics Lecture Notes, 2022
These lecture notes provide an overview of the renormalization group (RG) as a successful framework to understand critical phenomena above the upper critical dimension $d_{\rm uc}$.

Finite-size scaling in the Kuramoto model [PDF]

Physical Review E, 2017
We investigate the scaling properties of the order parameter and the largest nonvanishing Lyapunov exponent for the fully locked state in the Kuramoto model with a finite number $N$ of oscillators. We show that, for any finite value of $N$, both quantities scale as $(K-K_L)^{1/2}$ with the coupling strength $K$ sufficiently close to the locking ...

Are critical finite-size scaling functions calculable from knowledge of an appropriate critical exponent?

, 1995
Critical finite-size scaling functions for the order parameter distribution of the two and three dimensional Ising model are investigated. Within a recently introduced classification theory of phase transitions, the universal part of the critical finite ...

Corrections to Finite Size Scaling in Percolation [PDF]

, 2003
A 1/L-expansion for percolation problems is proposed, where L is the lattice finite length. The square lattice with 27 different sizes L = 18, 22 ... 1594 is considered.

Finite-size scaling in two-dimensional superfluids [PDF]

Physical Review B, 1994
Using the $x-y$ model and a non-local updating scheme called cluster Monte Carlo, we calculate the superfluid density of a two dimensional superfluid on large-size square lattices $L \times L$ up to $400\times 400$. This technique allows us to approach temperatures close to the critical point, and by studying a wide range of $L$ values and applying ...

Finite-Size Scaling at the Jamming Transition [PDF]

, 2012
We present an analysis of finite-size effects in jammed packings of N soft, frictionless spheres at zero temperature. There is a 1/N correction to the discrete jump in the contact number at the transition so that jammed packings exist only above ...

Indentation size effects: A study via finite similitude scaling theory

Materials & Design
Indentation is a widely applied measurement technique that can be reasonably categorized as nondestructive for evaluating mechanical properties. It is practically attractive and favored because it is easy to use and quick to apply at relatively low cost.

Finite-size scaling of directed percolation in the steady state

, 2007
Recently, considerable progress has been made in understanding finite-size scaling in equilibrium systems. Here, we study finite-size scaling in non-equilibrium systems at the instance of directed percolation (DP), which has become the paradigm of non ...

Finite Size Scaling and ``perfect'' actions: the three dimensional Ising model [PDF]

, 1998
Using Finite-Size Scaling techniques, we numerically show that the first irrelevant operator of the lattice $\lambda\phi^4$ theory in three dimensions is (within errors) completely decoupled at $\lambda=1.0$.
