A bstract We consider entanglement entropies of finite spatial intervals in Minkowski radiation baths coupled to the eternal black hole JT gravity, and related problem involving free fermion BCFT thermofield double state. show that non-monotonic entropy evolution precisely matches theory a high temperature limit, results have form expected for CFTs with quasiparticle description. Both exhibit r...

quadruped robots have unique capabilities for motion over uneven natural environments. this article presents a stable gait for a quadruped robot in such motions and discusses the inverse-dynamics control scheme to follow the planned gait. first, an explicit dynamics model will be developed using a novel constraint elimination method for an 18-dof quadruped robot. thereafter, an inverse-dynamics...

the determination of gyration radius is a strong research for configuration of a macromolecule. italso reflects molecular compactness shape. in this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. we studiedthe changes of these factors as a function of temperature for acetylcholine receptor protein in gasphase with n...

A bstract We expand on our results in [1] to present a broad new class of gravitational observables asymptotically Anti-de Sitter space living general codimension-zero regions the bulk spacetime. By taking distinct limits, these can reduce well-studied holographic complexity proposals, e.g., volume maximal slice and action or spacetime Wheeler-DeWitt patch. As with codimension-one family found ...

potassium channels allow potassium flux and are essential for the generation of electric current acrossexcitable membranes. potassium channels are also the targets of various intracellular controlmechanisms; such that the suboptimal regulation of channel function might be related to pathologicalconditions. realistic studies of ion current in biologic channels present a major challenge for compu...

In this work we analyze the nonequilibrium transport through a quantum impurity (quantum dot or molecule) attached to ferromagnetic leads by using hybrid numerical renormalization group-time-dependent density matrix group thermofield quench approach.For this, study bias dependence of differential conductance system, which shows finite zero-bias peak, characteristic Kondo resonance and reminisce...

A bstract We prove a recent conjecture by Harlow and Ooguri concerning universal formula for the charged density of states in QFT at high energies global symmetries associated with finite groups. An equivalent statement, based on entropic order parameter operators thermofield double state, was proven previous article Casini, Huerta, Pontello, present author. Here we describe how statement about...

We refine previous investigations on de Sitter space and extremal surfaces anchored at the future boundary $I^+$. Since such do not return, they require extra data or conditions in past (interior). In entirely Lorentzian spacetime, this leads to future-past timelike stretching between $I^\pm$. Apart from an overall $-i$ factor (relative spacelike $AdS$) their areas are real positive. With a no-...

We propose a measure of quantum state complexity defined by minimizing the spread wave-function over all choices basis. Our is controlled "survival amplitude" for to remain unchanged, and can be efficiently computed in theories with discrete spectra. For continuous Hamiltonian evolution, it generalizes Krylov operator states. apply our methods harmonic inverted oscillators, particles on group m...

We study some general properties of coupled quantum systems. consider simple interactions between two copies identical Hamiltonians such as the SYK model, Pauli spin chains with random magnetic field and harmonic oscillators. Such couplings make ground states close to thermofield double uncoupled Hamiltonians. For we push numerical computation further towards thermodynamic limit so that an extr...
