Nuclear decay parameter oscillations as possible signal of quantum-mechanical nonlinearity and emergent gravity
S. N. Mayburov
Several experimental groups reported the evidence of multiple periodic modulations of nuclear decay constants which amplitudes are of the order .1% and periods of one year, 24 hour…
Damped Oscillator with delta-kicked frequency in probability representation of quantum mechanic
Vladimir N. Chernega, Olga V. Man'ko
We obtain the tomogram of squeezed correlated states of a quantum parametric damped oscillator in an explicit form. We study the damping within the framework of the Caldirola--Kana…
On collective Rabi splitting in nanolasers and nano-LEDs
Emil C. André, Igor E. Protsenko, Alexander V. Uskov +2
We analytically calculate the optical emission spectrum of nanolasers and nano-LEDs based on a model of many incoherently pumped two-level emitters in a cavity. At low pump rates w…
Geometry and Entanglement of Two-Qubit States in the Quantum Probabilistic Representation
Julio A. López-Saldívar, Octavio Castaños, Eduardo Nahmad-Achar +3
A new geometric representation of qubit and qutrit states based on probability simplexes is used to describe the separability and entanglement properties of density matrices of two…
Commutative Fuzzy Geometry and Quantum Particle Dynamics
S. N. Mayburov
Fuzzy geometry considered as the possible mathematical framework for reformulation of quantum-mechanical formalism in geometric terms. In this approach the states of massive partic…
New entropic inequalities for qudit(spin j=9/2)
V. I. Manko, T. Sabyrgaliyev
We consider information characteristics of single qudit state (spin j=9/2), such as von Neumann entropy, von Neumann mutual information. We review different mathematical properties…
Probability representation of quantum observable and quantum states
Vladimir N. Chernega, Olga V. Man'ko, Vladimir I. Man'ko
We introduce the probability distributions describing quantum observables in conventional quantum mechanics and clarify their relations to the tomographic probability distributions…
Normalized non-redundant vector tomographic portraits of spin states
Ya. A. Korennoy
Non-redundant and normalized four-component vector tomographic portrait fully describing the states of spin 1/2 quantum particles was introduced. Dequantizer and quantizer for such…
Darkness of two-mode squeezed light in Λ-type atomic system
E. S. Moiseev, Arina Tashchilina, S. A. Moiseev +1
We show that, under certain circumstances, an optical field in a two-mode squeezed vacuum (TMSV) state can propagate through a lossy atomic medium without degradation or evolution.…
Triangle geometry of the qubit state in the probability representation expressed in terms of the triada of Malevich's Squares
Vladimir N. Chernega, Olga V. Man'ko, Vladimir I. Man'ko
We map the density matrix of the qubit (spin-1/2) state associated with the Bloch sphere and given in the tomographic probability representation onto vertices of a triangle determi…
Center of mass tomography and Wigner function for multimode photon states
Ivan Dudinets, Vladimir Manko
Tomographic probability representation of multimode electromagnetic field states in the scheme of center-of-mass tomography is reviewed. Both connection of the field state Wigner f…
God plays coins or superposition principle for classical probabilities in quantum suprematism representation of qubit states
Vladimir N. Chernega, Olga V. Man'ko, Vladimir I. Man'ko
For three given probability distributions describing positions of three classical coins the quantum density matrix of spin- state is constructed and its matrix elements are as…
Entropic bounds between two thermal equilibrium states
Julio A. López-Saldívar, Octavio Castaños, Margarita A. Man'ko +1
The positivity conditions of the relative entropy between two thermal equilibrium states and are used to obtain upper and lower bounds for the subtraction of th…
