Hairy black holes in AdS with Robin boundary conditions [PDF]
Journal of High Energy Physics, 2023 Abstract We study hairy black holes in Einstein-Maxwell-complex scalar theory in four-dimensional asymptotically global anti-de Sitter (AdS) spacetime when the Robin boundary conditions are imposed on the scalar field. This setup is dual to the double trace deformation of strongly interacting field theory on R × S2 by charged ...

Logarithmic minimal models with Robin boundary conditions [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2016 We consider general logarithmic minimal models ${\cal LM}(p,p')$, with $p,p'$ coprime, on a strip of $N$ columns with the $(r,s)$ Robin boundary conditions introduced by Pearce, Rasmussen and Tipunin. The associated conformal boundary conditions are labelled by the Kac labels $r\in{\Bbb Z}$ and $s\in{\Bbb N}$.

An optimization problem in thermal insulation with Robin boundary conditions [PDF]
Communications in Partial Differential Equations, 2021 We study thermal insulating of a bounded body $ \subset \mathbb{R}^n$. Under a prescribed heat source $f\geq 0$, we consider a model of heat transfer between $ $ and the environment determined by convection; this corresponds, before insulation, to Robin boundary conditions. The body is then surrounded by a layer of insulating material of thickness of

Free boundary cluster with Robin condition on the transmission interface
Calculus of Variations and Partial Differential Equations, 2023 We formulate and study a variational two-phase free boundary problem with Robin condition on the interface between the two phases, and we prove existence and regularity of solutions in dimension ...

Equivalent Robin boundary conditions for acoustic and elastic media [PDF]
Mathematical Models and Methods in Applied Sciences, 2016 We present equivalent conditions and asymptotic models for a diffraction problem of acoustic and elastic waves. The mathematical problem is set with a Robin boundary condition. Elastic and acoustic waves propagate in a solid medium surrounded by a thin layer of fluid medium. Due to the thinness of the layer with respect to the wavelength, this problem

Straight Quantum Waveguide with Robin Boundary Conditions [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We investigate spectral properties of a quantum particle confined to an infinite straight planar strip by imposing Robin boundary conditions with variable coupling. Assuming that the coupling function tends to a constant at infinity, we localize the essential spectrum and derive a sufficient condition which guarantees the existence of bound states ...

Size estimates of unknown boundaries with a Robin-type condition [PDF]
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2017 We deal with the problem of determining an unknown part of the boundary of an electrical conductor that is inaccessible for external observation and where a corrosion process is going on. We obtain estimates of the size of this damaged region from above and below.

On the torsion function with Robin or Dirichlet boundary conditions
Journal of Functional Analysis, 2014 For $p\in (1,+\infty)$ and $b \in (0, +\infty]$ the $p$-torsion function with Robin boundary conditions associated to an arbitrary open set $\Om \subset \R^m$ satisfies formally the equation $- _p =1$ in $\Om$ and $|\nabla u|^{p-2} \frac{\partial u}{\partial n} + b|u|^{p-2} u =0$ on $\partial \Om$.

Boundary dynamics and multiple reflection expansion for Robin boundary conditions [PDF]
Physical Review D, 2002 In the presence of a boundary interaction, Neumann boundary conditions should be modified to contain a function S of the boundary fields: (\nabla_N +S) =0. Information on quantum boundary dynamics is then encoded in the $S$-dependent part of the effective action.
