Relativistic BCS-BEC Crossover at Quark Level
EPJ Web of Conferences, 2010 The non-relativistic G0G formalism of BCS-BEC crossover at finite temperature is extended to relativistic fermion systems. The theory recovers the BCS mean field approximation at zero temperature and the non-relativistic results in a proper limit.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Interacting fermions in external fields, at finite temperature and non-zero density [PDF]
, 2023 In this thesis we investigate a certain class of low-dimensional fermionic quantum field theories with four-Fermi interactions. Such theories are commonly used as effective low-energy models for quantum chromodynamics, the theory of strong interactions ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Quadratic density response function of a two dimensional electron gas
Results in Physics, 2015 A retarded quadratic density response function of a two dimensional non-relativistic homogeneous electron gas at zero temperature is obtained in a closed-form written in terms of a non-analytic complex function.

Numerical computation for parallel plate thermoacoustic heat exchangers in standing wave oscillatory flow [PDF]
, 2011 A simplified computational method for studying the heat transfer characteristics of parallel plate thermoacoustic heat exchangers is presented. The model integrates the thermoacoustic equations of the standard linear theory into an energy balance-based ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
