Ultrafast generation and decay of a surface metal [PDF]
Nature Communications, 2021 AbstractBand bending at semiconductor surfaces induced by chemical doping or electric fields can create metallic surfaces with properties not found in the bulk, such as high electron mobility, magnetism or superconductivity. Optical generation of such metallic surfaces on ultrafast timescales would be appealing for high-speed electronics.

Magnetic Field Decay in Neutron Stars. Analysis of General Relativistic Effects [PDF]
, 2000 An analysis of the role of general relativistic effects on the decay of neutron star's magnetic field is presented. At first, a generalized induction equation on an arbitrary static background geometry has been derived and, secondly, by a combination of ...

General decay estimate for coupled plate problem with memory
Results in Applied Mathematics, 2022 This article considers a coupled system of non-linear plate equations with partially hinged boundary conditions. By assuming general conditions on the relaxation functions, we show that the associated energy functional satisfy a general decay estimate ...

Classical Loschmidt echo in chaotic many-body systems [PDF]
, 2005 General theoretic approach to classical Loschmidt echoes in chaotic systems with many degrees of freedom is developed. For perturbations which affect essentially all degrees of freedom we find a doubly exponential decay with the rate determined by the ...

Optical angular momentum: Multipole transitions and photonics [PDF]
, 2010 The premise that multipolar decay should produce photons uniquely imprinted with a measurably corresponding angular momentum is shown in general to be untrue.

General decay for a viscoelastic wave equation with strong time-dependent delay
Boundary Value Problems, 2017 A viscoelastic wave equation with strong damping and strong time-dependent delay in the internal feedback is considered. Under the assumption | μ 2 | < 1 − d μ 1 $|\mu_{2}|

Correlations, spectral gap, and entanglement in harmonic quantum systems on generic lattices
, 2006 We investigate the relationship between the gap between the energy of the ground state and the first excited state and the decay of correlation functions in harmonic lattice systems.

Temporal decay bounds in generalized heat conduction
Journal of Mathematical Analysis and Applications, 2004 The authors consider the generalized Maxwell-Cattaneo model for heat conduction in \(\mathbb R^N\) \((N = 2, 3)\). By using a suitable change of variable for the temperature \(T\) and exploiting the multiplier method, they establish an exponential decay bounds for \(T\), as well as its first partial derivatives, in the \(L_2(\Omega)\) norm.
