Effective Hamiltonian description on monitored Majorana chains: correlated power-law hoppings and unconventional entanglement scaling
Ken Mochizuki, Hisanori Oshima, Ryusuke Hamazaki +1
We investigate the structures of effective Hamiltonians governing monitored dynamics of a one-dimensional Majorana chain through the Lyapunov spectral analysis. We focus on a gaple…
Clifford Ergotropy
Somnath Maity, Ryusuke Hamazaki
We discuss the interplay between thermodynamics and magic resources in closed quantum dynamics by introducing Clifford ergotropy, the amount of extractable energy under the restric…
Anomalous waiting-time distributions in postselection-free quantum many-body dynamics under continuous monitoring
Kazuki Yamamoto, Ryusuke Hamazaki
We investigate waiting-time distributions (WTDs) of quantum jumps in continuously monitored quantum many-body systems, whose unconditional dynamics lead to the trivial infinite-tem…
Quantum Many-Body Mpemba Effect through Resonances
Shion Yamashika, Ryusuke Hamazaki
Relaxation towards equilibrium is often assumed to be slower when a system starts farther from equilibrium, but this intuition fails in the Mpemba effect. Recent advances in contro…
Universal Family-Vicsek scaling in quantum gases far from equilibrium
Kiryang Kwon, Kazuya Fujimoto, Junhyeok Hur +6
Fluctuations in the growing surfaces of classical systems can exhibit universal scaling behavior, known as Family-Vicsek (FV) scaling. Although this phenomenon was originally disco…
Quantum Error Mitigation Simulates General Non-Hermitian Dynamics
Hiroki Kuji, Suguru Endo, Tetsuro Nikuni +2
While non-Hermitian Hamiltonians enable exotic dynamical phenomena, implementing their nonunitary time evolution on near-term quantum devices remains challenging. We propose a hard…
