The wave operator representation of quantum and classical dynamics
Gerard McCaul, Dmitry V. Zhdanov, Denys I. Bondar
The choice of mathematical representation when describing physical systems is of great consequence, and this choice is usually determined by the properties of the problem at hand.…
Joint quantum-classical Hamilton variation principle in the phase space
Dmitry V. Zhdanov, Denys I. Bondar
We show that the dynamics of a closed quantum system obeys the Hamilton variation principle. Even though quantum particles lack well-defined trajectories, their evolution in the Hu…
Quantum and semiclassical dynamics as fluid theories where gauge matters
Dmitry V. Zhdanov, Denys I. Bondar
The family of trajectories-based approximations employed in computational quantum physics and chemistry is very diverse. For instance, Bohmian and Heller's frozen Gaussian semiclas…
Comment on "Control landscapes are almost always trap free: a geometric assessment"
Dmitry V. Zhdanov
We analyze a recent claim that almost all closed, finite dimensional quantum systems have trap-free (i.e., free from local optima) landscapes (B. Russell et.al. J. Phys. A: Math. T…
Friction as a consistent quantum-mechanical concept
Dmitry V. Zhdanov, Denys I. Bondar, Tamar Seideman
A quantum analog of friction (understood as a completely positive, Markovian, translation-invariant and phenomenological model of dissipation) is known to be in odds with the detai…
Theory of quantum control landscapes: Overlooked hidden cracks
Dmitry V. Zhdanov
Why does controlling quantum phenomena appear easy to achieve? Why do effective quantum controls appear easy to find? Why is chemical synthesis and property optimization easier tha…
Structure of optimal policies in quantum control
Dmitry V. Zhdanov, Tamar Seideman
Using the Pontryagin maximum principle, the generic structure of optimal policies is deduced for typical quantum control tasks involving coherent lasers, magnetic fields and reserv…
No thermalization without correlations
Dmitry V. Zhdanov, Denys I. Bondar, Tamar Seideman
The proof of the long-standing conjecture is presented that Markovian quantum master equations are at odds with quantum thermodynamics under conventional assumptions of fluctuation…
Quantum friction: environment engineering perspectives
Dmitry V. Zhdanov, Denys I. Bondar, Tamar Seideman
We prove a generalization of the Lindblad's fundamental no-go result: A quantum system cannot be completely frozen and, in some cases, even thermalized via translationally invarian…
Non-conservative Forces via Quantum Reservoir Engineering
Shanon L. Vuglar, Dmitry V. Zhdanov, Renan Cabrera +3
A systematic approach is given for engineering dissipative environments that steer quantum wavepackets along desired trajectories. The methodology is demonstrated with several illu…
Quantum optimal environment engineering for efficient photoinduced charge separation
Dmitry V. Zhdanov, Tamar Seideman
The possibility to induce predetermined coherent quantum dynamics by controlling only the dissipative environmental parameters (such as temperature and pressure) is studied using t…
Role of control constraints in quantum optimal control
Dmitry V. Zhdanov, Tamar Seideman
The problems of optimizing the value of an arbitrary observable of the two-level system at both a fixed time and the shortest possible time is theoretically explored. Complete iden…
Wigner representation of the rotational dynamics of rigid tops
Dmitry V. Zhdanov, Tamar Seideman
We propose a methodology to design Wigner representations in phase spaces with nontrivial topology having evolution equations with desired mathematical properties. As an illustrati…
Wigner phase space distribution as a wave function
Denys I. Bondar, Renan Cabrera, Dmitry V. Zhdanov +1
We demonstrate that the Wigner function of a pure quantum state is a wave function in a specially tuned Dirac bra-ket formalism and argue that the Wigner function is in fact a prob…
