Entanglement structure for finite system under dual-unitary dynamics
The dynamics of quantum many-body systems in the chaotic regime are of particular interest due to the associated phenomena of information scrambling and entanglement generation within the system. While these systems are typically intractable using traditional numerical methods, an effective framework can be implemented based on dual-unitary circuits which have emerged as a minimal model for maximally chaotic dynamics. In this work, we investigate how individual two-body operators influence the …

My good, how much I hate the internet and computers. I just wanna scream louder than I ever have at them, my good, I’m angry right now. All my life lost to a dumb-ass screen, brainwashed by the latest tech psyops on YouTube nobody asked for.
It’s like being trapped in a never-ending circus of clicks and scrolls, where the clowns are algorithms and the ringmaster is some faceless corporation laughing at how easy it is to fool us.
Computers and the internet promised freedom but del…

Two-site entanglement in the two-dimensional Hubbard model
The study of entanglement in strongly correlated electron systems typically requires knowledge of the reduced density matrix. Here, we apply the parquet dynamical vertex approximation to study the two-site reduced density matrix at varying distance, in the Hubbard model at weak coupling. This allows us to investigate the spatial structure of entanglement in dependence of interaction strength, electron filling, and temperature. We compare results from different entanglement measures, and benchma…

"I Said Things I Needed to Hear Myself": Peer Support as an Emotional, Organisational, and Sociotechnical Practice in Singapore
Peer support plays a vital role in expanding access to mental health care by providing empathetic, community-based support outside formal clinical systems. As digital platforms increasingly mediate such support, the design and impact of these technologies remain under-examined, particularly in Asian contexts. This paper presents findings from an interview study with 20 peer supporters in Singapore, who operate across diverse online, offline, and hybrid environments. Through a thematic analysis,…

From the BBC News website:
After a phone-call with Russia's Vladimir Putin last week, Trump said he was "not happy" that progress had not been made towards ending the war, and he has since complained that Putin's "very nice" attitude turned out to be meaningless.

How has #Trump gone 79 years without learning that people don’t always mean what they say? …

Ukraine to receive US Patriot air defence systems, says Trump
The US president says he will sell weapons to Nato, which would then give them to Ukraine.

Soon, I’ll be throwing away all my desktop computers as well, though I’m keeping my Lenovo Thinkpad around. I hate computers, yet I use them.
To me, computers are just junk nobody asked for. They’re glowing traps that keep us hooked, scrolling and clicking away our time for endless feeds. No matter the OS or hardware, it’s all distraction from reality.
Yes, Linux can free us and all that, and even the hardware can be part of that freedom. But the computers themselves remain a cir…

Saturable nonlinearity induced quantum correlations in optomechanics
We propose a scheme that induces quantum correlations in optomtomechanical systems. Our benchmark system consists of two optically coupled optical cavities which interact with a common mechanical resonator. The optical cavities host saturable nonlinearity which triggers either gain or losses in each cavity. Without these nonlinearities, there are no quantum correlations, i.e., entanglement and steering, generated in the system. By turning on the nonlinearities, gain and losses are switched on, …

AffectMachine-Pop: A controllable expert system for real-time pop music generation
Music is a powerful medium for influencing listeners' emotional states, and this capacity has driven a surge of research interest in AI-based affective music generation in recent years. Many existing systems, however, are a black box which are not directly controllable, thus making these systems less flexible and adaptive to users. We present \textit{AffectMachine-Pop}, an expert system capable of generating retro-pop music according to arousal and valence values, which can either be pre-determ…

Wigner's friend scenarios: on what to condition and how to verify the predictions
Wigner's friend experiment and its modern extensions display the ambiguity of the quantum mechanical description regarding the assignment of quantum states. While the friend applies the state-update rule to the system upon observing an outcome of her measurement in a quantum system, Wigner describes the friend's measurement as a unitary evolution, resulting in an entangled state for the composite system of the friend and the system. In this respect, Wigner is often referred to as a "superobserv…
