Quantum simulation of ultracold atoms in optical lattice based on dynamical mean-field theory
Acta Physica Sinica, 2023 With the development of atomic cooling technology and optical lattice technology, the quantum system composed of optical lattice and ultracold atomic gas has become a powerful tool for quantum simulation. The purity and highly controllable nature of the optical lattice give it a strong regulatory capability.

Journal of High Energy Physics, 2018 A generic feature of string compactifications is the presence of many scalar fields, called moduli. Moduli are usually displaced from their post-inflationary minimum during inflation.

Monte Carlo simulation of SU(2) gauge theory with fermions on a four-dimensional lattice [PDF]
, 1982 After integration over the fermions in an SU(2) lattice gauge theory, the effective fermionic action may be expressed as a sum over all possible closed gauge field loops with corresponding weight factors. We approximate this sum and perform a Monte Carlo

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

INDICATIONS ON THE HIGGS BOSON MASS FROM LATTICE SIMULATIONS
, 2004 The 'triviality' of Φ44 has been traditionally interpreted within perturbation theory where the prediction for the Higgs boson mass depends on the magnitude of the ultraviolet cutoff A.

Advanced Engineering Materials, EarlyView.Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

Sampling in lattice field theory with flow-based generative models [PDF]
Quantum field theories can be non-perturbatively regularised by discretising the fields on a space-time lattice, and in many cases one can define a corresponding Euclidean theory with real, positive-definite path integral measure by rotating to imaginary

Calculation of the free energy of crystalline solids [PDF]
, 2013 The prediction of the packing of molecules into crystalline phases is a key step in understanding the properties of solids. Of particular interest is the phenomenon of polymorphism, which refers to the ability of one compound to form crystals with ...
