Dear all, Can you let me and Rocío know whom of you needs a monitor or a 2nd monitor? Also, check what type of adapter your computer needs. Many laptops use HDMI, but some are different, and our more recent Lenovo towers use displayports. This is the one I have for my Lenovo PC: https://urldefense.com/v3/__https://www.hp.com/es-es/shop/product.aspx?id=9… Please remember to put Rocío in cc :) Rocío Sola <rosolaji(a)gmail.com> Best, JJ

Lola's new e-mail address
by lolaestevediaz＠correo.ugr.es 01 Oct '24

01 Oct '24

Hello! As I have now an official onsager e-mail account, I would like to start using it for work stuff. My new address is desteve(a)onsager.ugr.es. I'm still using the old UGR one as I'm going to be using it for the master (lolaestevediaz(a)correo.ugr.es) but, ideally, I will use it this year for that purpose only. Then, I would appreciate if you included me in the corresponding mailing lists as I'll be unsubscribing soon with the other account. Thank u very much ^^ Lola

Dear all; As you well know, we’re planning a big purchase with furniture and other items for the office. I’ve updated again the “Lista de la compra” file on Google Drive, but I will need you to check it again. Also, for those who asked for magnetic whiteboards, I’ll be so thankful if you add some links to examples, considering different prices. You will find everything here: https://docs.google.com/spreadsheets/d/186XSMqSwf2QU7rGvYkcfRRpoPpHhoks93HK… If you have any doubts or questions, don’t hesitate to contact me. Cheers, Rocío.

Protocolo para compras
by Juani Bermejo Vega 30 Sep '24

30 Sep '24

Dear all, I think we should make some sort of infogram to visualize what is the right way to book flights/hotel and pay conference fees for all employees of the group. Some simple graph. I am finishing the ICE9 bookings and the rules are just very confusing for different projects and depend on whether you pay with the credit card or by transfer. Please try to be careful booking stuff yourself. It is better to ask one of the PIs or Rocío to do the purchases in order to avoid getting a wrong invoice with the wrong data or we wont get reimbursed. Best, JJ

Reminder of seminar: Pseudospectral method for solving PDEs using Matrix Product States
by Daniel Manzano 26 Sep '24

26 Sep '24

El grupo de Termodinámica y Computación Cuántica les invita al siguiente seminario Fecha: Viernes 27/9/2024 Hora: 11:00 am Lugar: Laboratorio de Fïsica Computacional, Dept de Electromagnetismo y Física de al Materia, Planta Baja, Facultad de Ciencias (junto al péndulo gigante) Ponente: Paula García-Molina (Instituto de Física Fundamental - CSIC) Titulo: Pseudospectral method for solving PDEs using Matrix Product States (arXiv:2409.02916) Resumen: This research focuses on solving time-dependent partial differential equations (PDEs), in particular the time-dependent Schrödinger equation, using matrix product states (MPS). We propose an extension of Hermite Distributed Approximating Functionals (HDAF) to MPS, a highly accurate pseudospectral method for approximating functions of derivatives. Integrating HDAF into an MPS finite precision algebra, we test four types of quantum-inspired algorithms for time evolution: explicit Runge-Kutta methods, Crank-Nicolson method, explicitly restarted Arnoli iteration and split-step. The benchmark problem is the expansion of a particle in a quantum quench, characterized by a rapid increase in space requirements, where HDAF surpasses traditional finite difference methods in accuracy with a comparable cost. Moreover, the efficient HDAF approximation to the free propagator avoids the need for Fourier transforms in split-step methods, significantly enhancing their performance with an improved balance in cost and accuracy. Both approaches exhibit similar error scaling and run times compared to FFT vector methods; however, MPS offer an exponential advantage in memory, overcoming vector limitations to enable larger discretizations and expansions. Finally, the MPS HDAF split-step method successfully reproduces the physical behavior of a particle expansion in a double-well potential, demonstrating viability for actual research scenarios. El seminario es accesible para los estudiantes de grado, a los que recomendamos encarecidamente que asistan. Para aquellos que no puedan asistir, también hemos configurado una reunión de Google donde el seminario se transmitirá en vivo. https://meet.google.com/csb-snng-bmu También os recordamos a todos la página web del Seminario de Grupos, https://ic1.ugr.es/eventos/wp/qjc/ donde se publicarán anuncios pasados, presentes y futuros.
