Unraveling the Secrets of Quantum Chaos: A New Look at Subsystem ETH

December 20, 2025

The world of quantum physics is full of mysteries. One big mystery is how quantum systems that are super chaotic can still act like they're in a state of balance. Scientists have been trying to figure this out with something called the Eigenstate Thermalization Hypothesis, or ETH for short. Now, the

Exploring Quantum Systems: Steady States and Eigenstate Behavior

November 21, 2025

In the world of quantum physics, understanding how systems behave is crucial. One key idea is the Eigenstate Thermalization Hypothesis (ETH). It suggests that individual quantum states can represent the thermal properties of a system. But what about systems that are always changing, not in balance?

Quantum Systems: The Memory Effect

June 13, 2025

Quantum systems in the condensed phase often show complex behaviors. This is due to a memory effect called non-Markovianity. Unlike its simpler, memoryless counterpart, non-Markovianity makes these systems harder to understand. Many chemical systems have shown signs of this complex behavior through

The Resurrection of LSM Theorem in Open Quantum Systems

January 13, 2025

You know how the LSM theorem works in closed systems, right? It's like a rule that says certain spin chains can't have a single, non-degenerate ground state. But what happens when these systems aren't closed anymore? They interact with their environment, and things get a bit messy. Imagine you're l
