New paper! arxiv.org/abs/2607.26156 ⚛️🧪 We study disorder-free localisation (DFL) - an intriguing phenomenon where dynamical degrees of freedom become localised and frozen, in the absence of the strong disorder (such as a random on-site magnetic field) normally needed to induce this effect. 🧵

Figure 1. (a) Schematic of a Z2 lattice gauge theory and its mapping to an effective spin chain with n-level bond disorder.
Top: Z2 gauge fields coupled to matter, with static external “flavor” particles coupled to the matter. Middle: After gauge fixing
and eliminating matter fields (see Appendix A), the model maps to a mixed-field Ising chain with disordered couplings gj , whose
signs and magnitudes are set by the occupations of the flavor particles. Bottom: Introducing n-level ancilla
Sj+1/2 renders
the model translationally invariant, enabling efficient disorder averaging (see Sec. V). (b) Each n-level ancilla requires log2(n)
qubits, with consequences for experimental simulation of disordered models. (c) Schematic summary of the phase diagrams
obtained in this work as a function of longitudinal field h and coupling µ. For n = 2 the system remains chaotic throughout
with slow dynamics at large h, while for n>2 localized and fragmented regimes emerge at large µ and h respectively.

How do faithfully quantum simulate disorder-free localization in lattice gauge theories? What is the minimal number and structure of gauge fields required? Motivated by a recent Google Quantum AI experiment, we answer this question in our new paper: arxiv.org/abs/2607.26156 @theoryleeds.bsky.social

🚨New paper alert🚨 A hot liquid can freeze faster than a cold liquid, a counterintuitive phenomenon called the Mpemba effect. In our new paper, we argue that a quantum version of this effect is ubiquitous across a large variety of chaotic quantum systems. arxiv.org/abs/2505.17181

Our featured article for April 2025 Quantum electrodynamics on a 1D lattice can lead to localization of charges, in contrast to the thermalizing dynamics. This study identifies the origin of such non-thermal signatures and attribute it to the fracturing of the underlying Hilbert space. rdcu.be/el8h7

New paper 🚨 arxiv.org/abs/2503.10761 Can quantum properties of black holes be realized in condensed matter models? We show that a chiral spin-chain which naturally admits a black hole description, realizes the Hayden-Preskill quantum teleportation protocol and shows Hawking-like radiation!

The quantum description of a black hole predicts that quantum information hidden behind the event horizon can be teleported outside almost instantaneously. In this work, we demonstrate that a chiral s...
