Internal cyclotron probe of the vertical polarizability of a surface-state electron on helium
Kirill Shulga
We study a surface-state electron on liquid helium in a tilted magnetic field. The tilt couples the cyclotron ladder to the vertical Rydberg-like subbands of the same electron and…
Charged-Lepton Koide Geometry from a Green-Dressed Compact Family Cycle
Kirill Shulga
Koide's charged-lepton relation suggests that is the natural family vector. We construct an effective compact-cycle realization in which this v…
Observation of individual vortex penetration in a coplanar superconducting resonator
Kirill Shulga, Shunsuke Nishimura, Pavel A. Volkov +7
We demonstrate the microwave signatures of individual Abrikosov-vortex penetration events in superconducting microwave resonators. resonators with a narrowed region near the…
Dissipative Stability and Dynamical Phase Transition in Two Driven Interacting Qubits
Kirill Shulga
We examine a two-qubit system influenced by a time-periodic external field while interacting with a Markovian bath. This scenario significantly impacts the temporal coherence chara…
Time molecules with periodically driven interacting qubits
K. V. Shulga, I. Vakulchyk, Y. Nakamura +2
We provide numerical evidence for a temporal quantum-mechanical interference phenomenon: time molecules (TM). A variety of such stroboscopic states are observed in the dynamics of…
