quantum dynamics

Tensor networks are a modern mathematical language that allows for a compact and efficient description of many-body quantum states, where direct computation becomes impossible. This talk discusses how this approach helps to understand the structure of entanglement and the dynamics of systems with a large number of particles, as well as how it is used for the numerical solution of quantum mechanical problems. The main ideas underlying tensor networks, intuitive examples of how they work, and key directions of practical application — from modeling many-body quantum systems to describing states of light — will be presented. Special attention is given to how tensor methods unify theory, computation, and experiment, opening new possibilities for the study of quantum systems.

We have the pleasure of announcing the 56th Symposium on Mathematical Physics to be held at the Institute of Physics, Nicolaus Copernicus University in Toruń, on 13-15 June 2025. Please, consult our web page https://smp.fizyka.umk.pl/smp/smp56/ for the programme and registration details. We hope that you will find time
and interest to join us for the meeting.

The Nature is always changed dynamically even in quantum mechanics. Quantum walks, which are quantum-mechanical analogues of random walks, are promising toy models to understand quantum dynamics. Surprisingly, these models can be experimentally demonstrated in some physical models. This workshop will be open for interdisciplinary researchers from the theoretical and experimental sides on the discrete-time and continuous-time quantum walks, for examples, mathematics, physics, quantum information, and statistical mechanics.

The 71st Scottish Universities Summer School in Physics will be held at the University of Strathclyde 21st July to 2nd August 2015. The official website is sussp71.phys.strath.ac.uk

The last 25 years have seen a shift in the emphasis of fundamental quantum physics theory and experiments, from simply generating and measuring quantum systems towards the purposeful control and manipulation of their dynamics. The main drivers for this are the rapidly-developing fields related to quantum technologies. These include metrology and sensing, as well as quantum simulation and computation.

The development of technologies for the 21st century, coupled with fundamental scientific inquiry, is driving new theoretical and experimental research on control in quantum systems. Experience has shown that systematic use of quantum control theory leads to significant improvements in technologies ranging from magnetic resonance to prototype quantum computers. Compelling case studies of quantum control have been developed in wide-ranging fields such as chemistry, metrology, optical networking and computer science.
