*Title: Thermalization of 2D Quantum Memories*
*Abstract: **The aim of a quantum memory is to protect an encoded quantum
state against errors for long periods of time. Quantum double models are a
class of 2D quantum memories proposed by Kitaev, in which the protection
from noise is due to the topological properties of the ground state
degeneracy.*
*Heuristic arguments have long pointed to a weakness of these models
against thermal noise processes. In this talk I will present a rigorous
estimate on the lifetime of these memories under a noise process modeled by
Davies generators which confirms these findings. This estimate is obtained
by proving that the spectral gap of the generator is lower bounded by a
positive constant uniformly in the system size.*
dear all
I am writing to announce the the call for a one-year post-doctoral
position at the Department of Mathematics, University of Pisa, about the
general topic of ``Analytical, probabilistic and statistical models with
application in natural and physical sciences'', funded by Università di
Pisa. This is a unique possibility to work with the Pisa probability
community:
https://www.dm.unipi.it/research/probability-and-mathematical-statistics/
The call for proposals is available at
https://bandi.unipi.it/public/Bandi/Detail/ed4975e8-cda2-46bf-ba28-e2b78b1d…

Dear Colleagues,
We would like to invite you to the following seminar that will take place on December 2nd at 11.00 in Padova.
The seminar will be held in person and online via the Zoom platform.

Title: Entropic turnpike estimates for the kinetic Schrödinger problem
Date and time: Friday, DECEMBER 2nd at 11.00
Place: room 2BC30 at the Department of Mathematics, University of Padova
Zoom link: https://unipd.zoom.us/j/86210155315
available also on the webpage https://www.math.unipd.it/~bianchi/seminari/
Abstract: The kinetic Schrödinger problem consists in finding the most likely evolution of a system of i.i.d. particles
driven by the underdamped Langevin dynamics, conditionally on their initial and final spatial configurations.
In this model each particle is described both by its position and velocity, but there is no a priori knowledge of the velocities
at the initial and final time. We will investigate the long-time behaviour of this kinetic system, proving that its most likely evolution
is exactly the one that spends most of the time exponentially close to the equilibrium configuration
(this property is commonly known in stochastic control theory as the turnpike property).
This short talk is based on a joint work with A. Chiarini, G. Conforti, Z. Ren.

Dear all,
I am delighted to announce the following Colloquium of The Department of
Mathematics and Applications
<https://www.matapp.unimib.it/it/eventi/colloquium-del-dipartimento-matemati…>,
University of Milano-Bicocca combined with the "Seminario Matematico e
Fisico di Milano <https://www.mate.polimi.it/smf/>”.
Speaker: Gady Kozma (Weizmann Institute of Science, Rehovot).
Title: Harmonic functions on groups.
Abstract: The classic Liouville theorem states that any bounded harmonic
function on Euclidean space is constant. The same holds for discretely
harmonic functions on a lattice. But what happens when the Euclidean
lattice is replaced by other graphs, in particular Cayley graphs of groups?
We will survey old and new results on relations between geometric and
algebraic properties of groups, harmonic functions and probability. Based
on joint work with various subsets of Itai Benjamini, Ariel Yadin, Hugo
Duminil-Copin, Gidi Amir and Maria Gerasimova.
The event will take place on November 30, 2022 at 14.30, in presence, Room
3014, 3rd floor of building U5, University of Milano-Bicocca, Via Roberto
Cozzi 55, 20125 Milano.
Light refreshments will be served after the talk.
Best regards,

Dear all,

Title: Affine Statistical Manifold: Finite State Space
Date and time: Monday 28 november at 2 pm
Place: room 508 at the Department of Mathematics, University of Genova
YouTube channel: 508dima
Abstract:
H. Weyl defines an affine space as a triple (M, V, ->), where V is a real vector space and M is a set with a binary external operation such that the parallelogram law holds. This notion was introduced in Relativity to derive simple notions of velocity and acceleration for curves in non-flat spaces. I have extended this setup to vector bundles to discuss the relevant affine geometries of the probability simplex. This type of study was called Information Geometry by S-i Amari. Especially, Amari and Nagaoka introduced a crucial notion of duality between mixture families and exponential families. J. Aitchinson developed a similar geometrical treatment of what he calls Statistics of Compositional Data. This affine setup is compatible but different with the metric set due to CR Rao and based on the observation that the Fisher information matrix of a statistical model defines a Riemannian metric on the probability simplex.
A previous lecture on similar topics is transcribed at http://www.j-npcs.org/online/vol2020/v23no2p221.pdf.
The present lecture is based on the material taken from https://arxiv.org/abs/2204.00917, https://www.mdpi.com/1099-4300/20/2/139, and https://arxiv.org/abs/1502.06718.<https://arxiv.org/abs/1502.06718>
The continuous case, not treated here, requires particular technical notions of differential geometry and functional analysis. See a summary at https://arxiv.org/abs/2210.07641
The seminar will be held in person and online via the YouTube channel: 508dima.
Best regards,
Fabio Rapallo
