Spontaneous Hawking Radiation from Dynamical Black-Hole Formation in Quantum Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We show that Hawking radiation spontaneously generated by dynamical black-hole formation can be realized in a local quantum spin model. Starting from the ground state corresponding…

Spin systems as quantum field theories in inflationary universe: A study with Unruh-DeWitt detectors
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We propose a method to probe the thermal properties of quantum field theory (QFT) in an inflationary universe simulated by spin systems. Our previous work (arXiv:2410.07587) has de…

Spin systems as quantum simulators of quantum field theories in curved spacetimes
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We demonstrate that a quantum field theory (QFT) in general two-dimensional curved spacetimes can be realized by a system of quantum spins or qubits. We consider a spin-1/2 model o…
