From now on I'm quoting this every time someone mentions the Bethe ansatz
@miniapeur Poisson. I see a lot of agreements - Poisson seems to model many of the processes that are associated in my mind with Zen Buddhism - raindrops on leaves, steps passing by the shop door, spikes of neurons firing, etc.

My hope is that these models will give new insights into thermal many-body physics, since they can both be implemented numerically and as quantum algorithms (with a bit of work).

It does not rely in the rotating wave approximation, it has quasi-local jump operators, and it has exact KMS detailed balance. This latter property was lacking in existing derivations e.g. https://t.co/Eh4lvWD78h

We develop a Markovian master equation in the Lindblad form that enables the efficient study of a wide range of open quantum many-body systems that would be inaccessible with existing methods. The...

This is essentially a particular case of the quantum Gibbs samplers that recently appeared https://t.co/HOK3kvEltw, and that many of us have ben focused on studying lately - with our derivation, we show that they indeed reproduce the natural weak coupling to a bath.

Preparing thermal and ground states is an essential quantum algorithmic task for quantum simulation. In this work, we construct the first efficiently implementable and exactly detailed-balanced...

New paper today! Very excited to announce we obtain, from first principles, a quantum master equation that both applies in the many-body regime and provably converges to the exact Gibbs state:

Starting from a microscopic description of weak system-bath interactions, we derive from first principles a quantum master equation that does not rely on the well-known rotating wave...

En este video, Matteo Scandi nos guía a través de uno de los debates más profundos de la física moderna: el conflicto entre realismo y mecánica cuántica. ¿Qué nos dice la mecánica cuántica sobre la realidad misma? 🔍 https://t.co/QWKh5MebHq

I will never understand why statisticians say “Type I error” and Type II error” when false positive and false negative are the same number of syllables and self-defining
Understanding Type I and Type II errors is the secret to unlocking the full potential of your statistical analysis. These errors are pivotal in hypothesis testing, where Type I errors represent false positives (incorrectly rejecting a true null hypothesis) and Type II errors

OH MY FUCKING GOD. YOUR ENTIRE BUSINESS RUNS ON MASSIVE AMOUNTS OF UNPAID LABOUR YOU HYPOCRITICAL SHITGIBBONS.
It can be hard to say no to service requests in academia. We sought advice on how to ensure researchers don’t get stuck doing unpaid labour https://t.co/SlEz9FKkTL
