Advanced Engineering Materials, EarlyView.Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Affine toda field theories on a half-line [PDF]
, 1999 This thesis is primarily concerned with the reflection factors of affine Toda field theories on the half-line x ≤ 0. First, we consider the classical background configurations of low rank a,(^(1)) affine Toda theories with a boundary, constructed by the ...

Simulating quantum field theory in curved spacetime with quantum many-body systems
Physical Review Research, 2020 This paper proposes a new general framework to build a one-to-one correspondence between quantum field theories in static (1+1)-dimensional curved spacetime and quantum many-body systems.

Aspects of pseudoentropy in field theories
Physical Review Research, 2021 In this paper, we explore properties of pseudoentropy in quantum field theories and spin systems from several approaches. pseudoentropy is a generalization of entanglement entropy such that it depends on both an initial and final state and has a clear ...

Quantum field theories with fermions in the Schrödinger representation [PDF]
, 2000 This thesis is concerned with the Schrödinger representation of quantum field theory. We describe techniques for solving the Schrödinger equation which supplement the standard techniques of field theory.

EFT beyond the horizon:stochastic inflation and how primordial quantum fluctuations go classical [PDF]
, 2014 We identify the effective theory describing inflationary super-Hubble scales and show it to be a special case of effective field theories appropriate to open systems.

Duality between the Deconfined Quantum-Critical Point and the Bosonic Topological Transition
Physical Review X, 2017 Recently, significant progress has been made in (2+1)-dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be related by hidden dualities; i.e., seemingly different field theories may ...

A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.
