Quantum field aspect of Unruh problem [PDF]
, 1999 It is shown using both conventional and algebraic approach to quantum field theory that it is impossible to perform quantization on Unruh modes in Minkowski spacetime.

On local boundary CFT and non-local CFT on the boundary
, 2004 The holographic relation between local boundary conformal quantum field theories (BCFT) and their non-local boundary restrictions is reviewed, and non-vacuum BCFT's, whose existence was conjectured previously, are constructed.Comment: 16 pages ...

Square Root Singularity in Boundary Reflection Matrix [PDF]
, 1996 Two-particle scattering amplitudes for integrable relativistic quantum field theory in 1+1 dimensions can normally have at most singularities of poles and zeros along the imaginary axis in the complex rapidity plane.

Four-point boundary connectivities in critical two-dimensional percolation from conformal invariance
Journal of High Energy Physics, 2018 We conjecture an exact form for an universal ratio of four-point cluster connectivities in the critical two-dimensional Q-color Potts model. We also provide analogous results for the limit Q → 1 that corresponds to percolation where the observable has a ...

Defect extremal surface as the holographic counterpart of Island formula
Journal of High Energy Physics, 2021 We propose defect extremal surface as the holographic counterpart of boundary quantum extremal surface. The defect extremal surface is defined by minimizing the Ryu-Takayanagi surface corrected by the defect theory.

Left-Right Entanglement Entropy of Boundary States
, 2014 We study entanglement entropy of boundary states in a free bosonic conformal field theory. A boundary state can be thought of as composed of a particular combination of left and right-moving modes of the two-dimensional conformal field theory.

Reflection Scattering Matrix of the Ising Model in a Random Boundary Magnetic Field [PDF]
, 1997 The physical properties induced by a quenched surface magnetic field in the Ising model are investigated by means of boundary quantum field theory in replica space. Exact boundary scattering amplitudes are proposed and used to study the averaged quenched

The reflection coefficient for minimal model conformal defects from perturbation theory
Journal of High Energy Physics, 2018 We consider a class of conformal defects in Virasoro minimal models that have been defined as fixed points of the renormalisation group and calculate the leading contribution to the reflection coefficient for these defects.

A Lorentzian inversion formula for defect CFT
Journal of High Energy Physics, 2020 We present a Lorentzian inversion formula valid for any defect CFT that extracts the bulk channel CFT data as an analytic function of the spin variable.

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation
