No meetups yet for this event.

Nobody has organized an actual get-together around this one so far. This page is the listing — it may run across a range of dates, and there's no organizer and no set plan behind it.

Someone needs to create a real meetup with a date, time and placeand that could be you. It takes about a minute, and everyone who marked themselves interested in this event can find it once you publish.

Want to Create Your Own Meetup for this Event?

This event is a listing — the concert, festival or activity itself. A meetup is your own smaller plan to go to it with other people: your date, your time, your meeting place. “A few of us are going, come with us.”

You don’t need permission and you don’t take anything over — this event isn’t changed at all. The venue, address and details are copied across, so you only pick when and where to meet.

As its organizer you get real tools to plan the when, where & what:

  • 📅 Member Availability — see which days and times everyone says they're usually free, so you know when to hold it.
  • 🎯 Member Interests & Cities — see everyone's interests and locations, so you know where to meet and what to include.
  • 🗺 Member Map — visually shows where most members are concentrated.
  • 🏷️ Activities & Voting — lists the tags and lets members vote on what they want to do.
  • 💬 Event Chat — everyone can discuss plans, who's bringing what, and last-minute changes.
  • RSVPs — who's coming, how likely, guest counts, and what they're looking forward to.
  • 🔗 Many Ways to Share or Invite — get the word out and grow attendance.

Your meetup starts hidden and set to “Only My Contacts”, with no date, so nothing is announced until you're ready. Nobody is notified when you create it. Once you set a date and switch Go Live? to Yes, it appears for people who marked themselves interested in this event.

ℹ️ About This Event

The Department of Mathematical Sciences invites you to attend the Colloquium through the Visiting Professor's Program by Dr. Yingda Cheng.

Title: Structure-Preserving numerical method for Lindblad master equation

Abstract: In this talk, we consider numerical discretization for Lindblad master equation, which is a fundamental model for open quantum system. We design high order methods that are completely positive and trace preserving (CPTP). This is achieved by Lawson integrator or Nested Picard integrator. To deal with curse of dimensionality, we introduce tensor train compression schemes for computing systems with many qubits. This is joint research with D. Appelo, J. Hu and P. deMalstro.

Biography: Dr. Cheng is a professor in the Department of Mathematics at Virginia Tech, and affiliated faculty with the Computational Modeling and Data Analytics program at Virginia Tech. Her areas of research are scientific computing, applied mathematics, and data-driven modeling & computation. Her interests focus on using modern data-driven, reduced order modeling and classical numerical analysis as tools to simulate highly complex and high dimensional multi-scale phenomena arising from science and engineering. Dr. Cheng received her B.S. degree from the University of Science and Technology of China in 2003 and her PhD degree in Applied Mathematics from Brown University. She held a postdoc position at the University of Texas at Austin. She was also a faculty member at Michigan State University.
