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…
Spacetime-Localized Response in Quantum Critical Spin Systems: Insights from Holography
Motoaki Bamba, Koji Hashimoto, Keiju Murata +2
According to the AdS/CFT correspondence, certain quantum many-body systems in -dimensions are equivalent to gravitational theories in -dimensional asymptotically AdS spac…
