Entanglement Generation and Decoherence in a Two-Qubit System Mediated by Relativistic Quantum Field
Yoshimasa Hidaka, Satoshi Iso, Kengo Shimada
Motivated by the Bose et al.-Matletto-Vedral (BMV) proposal for detecting quantum superposition of spacetime geometries, we study a toy model of a quantum entanglement generation b…
Emergent higher-form symmetry in Higgs phases with superfluidity
Yoshimasa Hidaka, Dan Kondo
We address emergent higher-form symmetry in Higgs phases with superfluidity. The emergent symmetry appears if a matter field is invariant under a transformation of a common subgrou…
Complementarity and causal propagation of decoherence by measurement in relativistic quantum field theories
Yoshimasa Hidaka, Satoshi Iso, Kengo Shimada
Entanglement generation by Newtonian gravitational potential between objects has been widely discussed to reveal the quantum nature of gravity. In this paper, we perform a quantum…
Angular Momentum Inheritance from the Schwinger Effect in (Chromo)electromagnetic Fields
Patrick Copinger, Yoshimasa Hidaka
The angular momentum of fermion pairs generated by the Schwinger effect is studied in homogeneous (chromo)electromagnetic fields, mimicking the early stages of a heavy-ion collisio…
Foundations and Applications of Quantum Kinetic Theory
Yoshimasa Hidaka, Shi Pu, Qun Wang +1
Many novel quantum phenomena emerge in non-equilibrium relativistic quantum matter under extreme conditions such as strong magnetic fields and rotations. The quantum kinetic theory…
