Notes on Real Quantum Mechanics in a Kahler Space
Irina Aref'eva, Igor Volovich
The necessity of complex numbers in quantum mechanics has long been debated. This paper develops a real Kahler space formulation of quantum mechanics [19], asserting equivalence to…
Black Brane/Bose Gase Duality and Third Law of Thermodynamics
Irina Aref'eva, Daniil Stepanenko, Igor Volovich
In the thermodynamics of black holes in asymptotically flat space, the third law of thermodynamics is violated, and entropy cannot be consistently modeled through conventional stat…
Revealing nonperturbative effects in the SYK model
Irina Aref'eva, Mikhail Khramtsov, Igor Volovich
We study the large saddle points of two SYK chains coupled by an interaction that is nonlocal in Euclidean time. We start from analytic treatment of the free case with an…
Evolution of the holographic entanglement entropy quantities for composite quantum systems
Irina Aref'eva, Oleg Inozemcev, Igor Volovich
Holographic entanglement entropy quantities for a three-party system are considered, namely tripartite information, total correlation and secrecy monotone. A holographic approach w…
Cauchy Problem on Non-globally Hyperbolic Spacetimes
I. Ya. Arefeva, T. Ishiwatari, I. V. Volovich
Solutions of the Cauchy problem for the wave equation on a non-globally hyperbolic spacetime, which contains closed timelike curves (time machines) are considered. It is proved, th…
On the Null Energy Condition and Cosmology
I. Ya. Aref'eva, I. V. Volovich
Field theories which violate the null energy condition (NEC) are of interest for the solution of the cosmological singularity problem and for models of cosmological dark energy wit…
