Canonical pairs in finite-dimensional Hilbert space
Ralph Adrian E. Farrales, Eric A. Galapon
A pair of Hermitian operators is canonical if they satisfy the canonical commutation relation. It has been believed that no such canonical pair exists in finite-dimensional Hilbert…
Controlled bit-flip of period-doubling and discrete time crystalline states in open systems
Roy D. Jara, Phatthamon Kongkhambut, Hans Keßler +2
In this work, we explore the robustness of a bit-flip operation against thermal and quantum noise for bits represented by the symmetry-broken pairs of the period-doubled (PD) state…
Characteristic time operators as quantum clocks
Ralph Adrian E. Farrales, Eric A. Galapon
We consider the characteristic time operator introduced in [E. A. Galapon, Proc. R. Soc. Lond. A, 458:2671 (2002)] which is bounded and self-adjoint. For a semibounded…
The role of conjugacy in the dynamics of time of arrival operators
Dean Alvin L. Pablico, John Jaykel P. Magadan, Carl Anthony L. Arguelles +1
The construction of time of arrival (TOA) operators canonically conjugate to the system Hamiltonian entails finding the solution of a specific second-order partial differential equ…
Observation of a phase transition from a continuous to a discrete time crystal
Phatthamon Kongkhambut, Jayson G. Cosme, Jim Skulte +4
Discrete (DTCs) and continuous time crystals (CTCs) are novel dynamical many-body states, that are characterized by robust self-sustained oscillations, emerging via spontaneous bre…
Theory of parametric resonance for discrete time crystals in fully-connected spin-cavity systems
Roy D. Jara, Dennis F. Salinel, Jayson G. Cosme
We pinpoint the conditions necessary for discrete time crystal (DTC) formation in fully connected spin-cavity systems from the perspective of parametric resonance by mapping these…
