Measuring the deviation from the superposition principle in interference experiments
New Journal of Physics, 2018 The Feynman path integral formalism has long been used for calculations of probability amplitudes. Over the last few years, it has been extensively used to theoretically demonstrate that the usual application of the superposition principle in slit based ...

Journal of High Energy Physics, 2018 We consider conformal defects with spins under the rotation group acting on the transverse directions. They are described in the embedding space formalism in a similar manner to spinning local operators, and their correlation functions with bulk and ...

Advanced Science, EarlyView.Phase‐resolved experiments and atomistic simulations reveal asynchronous ordering behaviors in a eutectic high‐entropy alloy during isothermal annealing. Distinct defect transport mechanisms are identified in coexisting B2 and BCC phases, showing that vacancy and interstitial mediated diffusion governs phase‐dependent thermal stability.

Elliptic symbol calculus: from elliptic polylogarithms to iterated integrals of Eisenstein series
Journal of High Energy Physics, 2018 We present a generalization of the symbol calculus from ordinary multiple polylogarithms to their elliptic counterparts. Our formalism is based on a special case of a coaction on large classes of periods that is applied in particular to elliptic ...

Path integral of topological defects in superfluids and superconductors [PDF]
openIn the first part of the thesis the student will study the finite-temperature path integral approach to superfluids and superconductors by analyzing different models involving bosons and fermions: Gross-Pitaevskii, Ginzburg-Landau and Bardeen-Cooper ...

Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor
Advanced Science, EarlyView.Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

A neural network wave formalism
, 2006 Using his path integral methodology, Feynman derived the constructs of quantum mechanics from the Lagrangian form of Newtonian mechanics. By employing a novel Lagrangian form of the canonical neural network equations, we derive analogously a complete ...

Advanced Science, EarlyView.Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Revisited apparent horizon entropy and GSL in modified gravity
European Physical Journal C: Particles and FieldsThis work presents a universal and revisited formalism for the entropy of the apparent horizon in modified gravity to investigate the validity of the Generalized Second Law (GSL) of thermodynamics.

A New Perspective on Path Integral Quantum Mechanics in Curved Space-Time
EPJ Web of Conferences, 2013 . A new approach to path integral quantum mechanics in curved space-time is presented for scalar particle propagation, expressed in terms of Lie transport and Fermi or Riemann normal co-ordinates to describe local curvature.
