Temporal entanglement entropy as a probe of renormalization group flow

Journal of High Energy Physics
The recently introduced concept of timelike entanglement entropy has sparked a lot of interest. Unlike the traditional spacelike entanglement entropy, timelike entanglement entropy involves tracing over a timelike subsystem.

Appearance of branched motifs in the spectra of BCN type Polychronakos spin chains

Nuclear Physics B, 2020
As is well known, energy levels appearing in the highly degenerate spectra of the AN−1 type of Haldane-Shastry and Polychronakos spin chains can be classified through the motifs, which are characterized by some sequences of the binary digits like ‘0’ and

Novel Aspects of QCD in Leptoproduction

, 2004
I review several topics in electroproduction which test fundamental aspects of QCD. These include the role of final-state interactions in producing diffractive leptoproduction processes, the shadowing of nuclear structure functions, and target-spin ...

N-flation in supergravity

Physics Letters B, 2014
We have constructed a large field N-flation model in the supergravity framework. In this simple set-up, N fields collectively drive inflation where each field traverses sub-Planckian field values.

Quartetting in Nuclear Matter

, 2012
A general theory for the condensation of strongly bound quartets in infinite nuclear matter is presented. Critical temperatures for symmetric and asymmetric nuclear matter are evaluated.

Complexity in Economic and Social Systems: Cryptocurrency Market at around COVID-19

Entropy, 2020
Social systems are characterized by an enormous network of connections and factors that can influence the structure and dynamics of these systems. Among them the whole economical sphere of human activity seems to be the most interrelated and complex. All

Preconditioned flow as a solution to the hierarchical growth problem in the generalized Lefschetz thimble method

Journal of High Energy Physics
The generalized Lefschetz thimble method is a promising approach that attempts to solve the sign problem in Monte Carlo methods by deforming the integration contour using the flow equation.

Overview of Antikaon-Nuclear Theory and Phenomenology

, 2007
Experimental evidence for antikaon-nuclear quasibound states is briefly reviewed. Theoretical and phenomenological arguments for and against deep antikaon-nucleus potentials which might allow for narrow quasibound states are reviewed, with recent ...

Parallel theoretical study of the two components of the prompt fission neutrons: Dynamically released at scission and evaporated from fully accelerated fragments

EPJ Web of Conferences, 2017
Prompt fission neutrons (PFN) angular and energy distributions for the reaction 235U(nth,f) are calculated as a function of the mass asymmetry of the fission fragments using two extreme assumptions: 1) PFN are released during the neck rupture due to the ...
