Title: Quantum Time-Dilation in Qubit Hypersurfaces

Abstract: The use of quantum spin systems to study the phenomenon of quantum time dilation leads to new insights into the quantum description of gravity. The basis of this description is the Page and Wootters mechanism, where entanglement between two quantum systems allows one to act as a clock for the other, influencing its time evolution. Intriguingly, when the clock system experiences a "gravitational-like interaction", the resulting time evolution can be described by a Time-Dilated Schrödinger equation. This equation includes a "redshift operator," a purely quantum effect that mimics gravitational time dilation. Here we discuss a novel, finite-dimensional framework in which a network of qubit systems can be used as a "global" clock for another non-interacting component of the universe. The result is the Time-Dilation induced Interaction Transfer (TiDIT) mechanism. TiDIT describes how time dilation due to the interaction of a qubit effectively changes the interaction between previously non-interacting parts of the universe. We will explore this concept with a practical example using two coupled qubits as a model for the quantum clock.

Speaker: Professor Jana Björn , Linköping University and OIST TSVP Visiting Scholar Title: The Dirichlet Problem and Boundary Regularity for Nonlinear Parabolic Equations

Abstract: As shown by Serrin in 1964, the growth at an isolated singularity of solutions to the elliptic equation div A(x, ∇u) = 0 in Rn (including p-harmonic functions with p > 1) is exactly determined by the dimension n and the parameter p associated with the equation. In this talk, I will discuss growth and integrability properties for p-harmonic Green functions and their gradients on weighted Rn, with a p-admissible weight, as well as on complete metric spaces equipped with a doubling measure supporting a p-Poincar´e inequality. In these situations, the dimension n is replaced by the local growth of the underlying measure near the isolated singularity, and the obtained growth and integrability exponents are sharp.

Abstract: The p-parabolic equation \[ \partial_t u = \Delta_p u := \dvg(|\nabla u|^{p-2}\nabla u) \] is a nonlinear cousin of the classical heat equation. As such, it offers both difficulties and advantages compared with the heat equation. In the talk, we consider the Perron method for solving the Dirichlet problem for the p-parabolic equation in general bounded domains in $R^{n+1}$. Compared to space-time cylinders, such domains allow the space domain to change in time. Of particular interest will be boundary regularity for such domains, i.e. whether solutions attain their boundary data in a continuous way. Relations between regular boundary points and barriers will be discussed, as well as some peculiar examples and surprising phenomena related to boundary regularity. Towards the end I will discuss the same type of questions for two other nonlinear cousins of the heat equation, the porous medium equation \[ \partial_t u = \dvg(u^m) \] and the so-called normalized p-parabolic equation \[ \partial_t u = |\nabla u|^{2-p}\Delta_p u. \] The talk is based on collaborations with Jana Bj\"orn (Link\"oping), Ugo Gianazza (Pavia), Mikko Parviainen (Jyv\"askyl\"a) and Juhana Siljander (Jyv\"askyl\"a).
