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…
Operator dependence and robustness of spacetime-localized response in a quantum critical spin chain
Daichi Imagawa, Keiju Murata, Daisuke Yamamoto
We investigate the phenomenon of spacetime-localized response in a quantum critical spin system, with particular attention to how it depends on the spatial profile and operator con…
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…
Engineering of a Low-Entropy Quantum Simulator for Strongly Correlated Electrons Using SU()-Symmetric Cold Atom Mixtures
Daisuke Yamamoto, Katsuhiro Morita
An advanced cooling scheme, incorporating entropy engineering, is vital for isolated artificial quantum systems designed to emulate the low-temperature physics of strongly correlat…
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…
