Quantum physicist. Will apply Cauchy-Schwarz for food.

There was this term, “API science,’’ that people would use to be like: “We’re doing science on a product? This isn’t science, it’s not reproducible.”

Researchers in “natural language processing” tried to tame human language. Then came the transformer.

Wondering if I should learn what all this "quantum chemistry" is about

Few texts have had a bigger positive impact in my scientific thinking than the first couple of pages of this arxiv.org/abs/0804.0327
The large deviation approach to statistical mechanics
The theory of large deviations is concerned with the exponential decay of probabilities of large fluctuations in random systems. These probabilities are important in many fields of study, including st...

I'm curious to know if people have encountered papermills in physics, it seems to be a huge problem (great blog btw) forbetterscience.com/2025/11/17/t...

Fun fact: yesterday I gave an outreach talk and when presenting Shor's algorithm I had 24=6×2×2 as an example of prime factoring

This is a fantastic essay and I wonder how much if it directly translates into science (e.g. paper writing as opposed to paper reading these days) danioffline.substack.com/p/everyone-w...
everyone wants to be a DJ, no one wants to dance
This is not an essay about nightlife, not exclusively.

Completely abhorred by the correct spelling being "simulatability" and not "simulability".

The most interesting idea I've learnt this week: arxiv.org/abs/2311.10304

In a dissipative setting, if one takes the thermodynamic limit first and then the limit of zero dissipation, you are left with a Liouvillian gap related to the relaxation of the closed system dynamics
Liouvillian-gap analysis of open quantum many-body systems in the weak dissipation limit
Recent experiments have reported that novel physics emerge in open quantum many-body sys- tems due to an interplay of interactions and dissipation, which stimulate theoretical studies of the many-body...

I am very happy to announce that my first published article „Rapid Thermalization of Dissipative Many-Body Dynamics of Commuting Hamiltonians“ is now published in Communications in Mathematical Physics.

I feel honored and humbled to have been accepted in such a prestigious journal.
Rapid Thermalization of Dissipative Many-Body Dynamics of Commuting Hamiltonians - Communications in Mathematical Physics
Quantum systems typically reach thermal equilibrium rather quickly when coupled to a thermal environment. The usual way of bounding the speed of this process is by estimating the spectral gap of the d...

I have many opinions on scientific writing and one of them is that we should typically aim to do better than "closing a gap" in the literature

A bit overwhelmed by how hard it is to keep track of results I want to learn about

In a new work, we show both numerically and analytically how expectations values of long-range models are robust to imperfections in the underlying Hamiltonian arxiv.org/abs/2506.16451
Stability of thermal equilibrium in long-range quantum systems
Experimental realizations of spin models are irremediably prone to errors, which can propagate through the system corrupting experimental signals. We study how such errors affect the measurement of lo...

Is it normal in some areas to cite papers in talks as [senior author] et al.? I saw it done recently and it seems kinda bad

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: arxiv.org/abs/2505.20064
Thermalization in open many-body systems and KMS detailed balance
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 approximation. Th...
