Restoring heat and particle flow in strongly coupled non-equilibrium devices
Noa Ludwin, Ohad Cremerman, Milan Šindelka +1
Under non-equilibrium conditions, energy/particle currents flow through a quantum system coupled to multiple baths. Although the fluxes increase in the weak coupling regime as the…
Spontaneous Emission from Electronic Metastable Resonance States
Amir Sivan, Milan Šindelka, Meir Orenstein +1
We demonstrate that calculating the spontaneous emission decay rate from metastable resonance states (states with finite lifetimes embedded in the continuum) requires considering t…
Equations of motion governing the dynamics of the exceptional points of parameterically dependent nonhermitian Hamiltonians
Milan Šindelka, Pavel Stránský, Pavel Cejnar
We study exceptional points (EPs) of a nonhermitian Hamiltonian whose parameters and . As the real control parameter is vari…
Violation of Detailed Balance in Quantum Open Systems
Robert Alicki, Milan Šindelka, David Gelbwaser-Klimovsky
We consider the dynamics of a quantum system immersed in a dilute gas at thermodynamics equilibrium using a quantum Markovian master equation derived by applying the low-density li…
Tuning quantum-classical correspondence of molecular systems in a cavity
Nimrod Moiseyev, Milan Sindelka
We show that the correspondence between quantum and classical mechanics can be tuned by varying the coupling strength between the cavity modes and an atom or a molecule. In the acc…
Continuum analogues of excited-state quantum phase transitions
Pavel Stránský, Milan Šindelka, Pavel Cejnar
Following our work [Phys. Rev. Lett. 125, 020401 (2020)], we discuss a semiclassical description of one-dimensional quantum tunneling through multibarrier potentials in terms of co…
Complex density of continuum states in resonant quantum tunneling
Pavel Stránský, Milan Šindelka, Michal Kloc +1
We introduce a complex-extended continuum level density and apply it to one-dimensional scattering problems involving tunneling through finite-range potentials. We show that the re…
Coalescence of two branch points in complex time marks the end of rapid adiabatic passage and the start of Rabi oscillations
Petra Ruth Kapralova-Zdanska, Milan Sindelka, Nimrod Moiseyev
We study theoretically the population transfer in two-level atoms driven by chirped lasers. It is known that in the Hermitian case, the rapid adiabatic passage (RAP) is stable for…
Excited State Quantum Phase Transitions Studied from a Non-Hermitian Perspective
Milan Šindelka, Lea F. Santos, Nimrod Moiseyev
A main distinguishing feature of non-Hermitian quantum mechanics is the presence of exceptional points (EPs). They correspond to the coalescence of two energy levels and their resp…
Strong impact of light induced conical intersections on the spectrum of diatomic molecules
Milan Sindelka, Nimrod Moiseyev, Lorenz S. Cederbaum
We show that dressing of diatomic molecules by running laser waves gives rise to conical intersections (CIs). Due to presence of such CIs, the rovibronic molecular motions are stro…
Theory of diatomic molecules in an external electromagnetic field from first quantum mechanical principles
Milan Sindelka, Nimrod Moiseyev
We study a general problem of the translational/rotational/vibrational/electronic dynamics of a diatomic molecule exposed to an interaction with an arbitrary external electromagnet…
Trapping of cold atoms by the quadrupole force
Nimrod Moiseyev, Milan Sindelka, Lorenz S. Cederbaum
Cold atoms are traditionally trapped by the dipole force in periodically spaced potential wells induced by the standing laser field. We derive here a theory beyond the conventional…
