UV Detection Tower Guide in Quarantine Zone: The Last Check

On Day 19, you’ll unlock the UV Detection Tower in Quarantine Zone: The Last Check. This tower helps you find hidden signs of infection. When activated, it floods the area with UV light, making any infection on your backpack or on a survivor visible.

![Yb atoms exhibit Kondo physics through a carefully engineered system where fermionic atoms in spin-1/2 states are selectively trapped - mobile in a ground band and localized in an excited band - creating an impurity interacting with a surrounding fermionic environment via both antiferromagnetic and potential interactions, effectively modeling [latex]Eq. (1)[/latex] and demonstrating how these interactions draw atoms either towards or away from the impurity site, as visualized by the wavefunction modulus.](https://arxiv.org/html/2601.11449v1/x1.png)
