Lattice regularisation of a non-compact boundary conformal field theory
Non-compact Conformal Field Theories (CFTs) are central to several aspects of string theory and condensed matter physics. They are characterised, in...

Gauge invariant canonical symplectic algorithms for real-time lattice strong-field quantum electrodynamics
A class of high-order canonical symplectic structure-preserving geometric algorithms are developed for high-quality simulations of the quantized...

The loom for general fishnet CFTs
We propose a broad class of d -dimensional conformal field theories of SU( N ) adjoint scalar fields generalising the 4 d Fishnet CFT (FCFT) discovered...

Random walks in correlated diffusivity landscapes
AbstractIn recent years, several experiments have highlighted a new type of diffusion anomaly, which was called Brownian yet non-Gaussian diffusion....

Synthesized magnetic field of a sawtooth superradiance lattice in Bose–Einstein condensates
Ultracold atoms have become one of the most exciting platforms to synthesize novel condensed matter physics. Here we realize a sawtooth superradiance...

Stochastic normalizing flows as non-equilibrium transformations
Normalizing flows are a class of deep generative models that provide a promising route to sample lattice field theories more efficiently than...

Interplay Between Electron Correlations, Magnetic State, and Structural Confinement in LaNiO3 Ultrathin Films
We report a theoretical study of the effects of electron correlations and structural confinement on the electronic properties and magnetic state of...

Thickness dependence of superconductivity in FeSe films
Thin films of FeSe on substrates have attracted attention because of their unusually high-temperature (T c ) superconducting properties whose origins...

Quasi-particle interference of the van Hove singularity in Sr2RuO4
The single-layered ruthenate Sr 2 RuO 4 is one of the most enigmatic unconventional superconductors. While for many years it was thought to be the best...

Discrete Field Theory: Symmetries and Conservation Laws
We present a general algorithm constructing a discretization of a classical field theory from a Lagrangian. We prove a new discrete Noether theorem...

The Free-Fermion Eight-Vertex Model: Couplings, Bipartite Dimers and Z-Invariance
We study the eight-vertex model at its free-fermion point. We express a new “switching” symmetry of the model in several forms: partition functions,...
