The role of imaginary companion in the life of only children: a qualitative study

BMC Psychiatry, 2023
Introduction An imaginary companion is an invisible or personified entity created by children for themselves. An imaginary companion typically serves as a companion to the child and plays a significant role in their life, especially for only children who

Multi-state quantum simulations via model-space quantum imaginary time evolution

npj Quantum Information, 2023
We introduce the framework of model space into quantum imaginary time evolution (QITE) to enable stable estimation of ground and excited states using a quantum computer. Model-space QITE (MSQITE) propagates a model space to the exact one by retaining its

The imaginary part of the gap function in color superconductivity [PDF]

, 2006
We clarify general properties of the energy gap regarding its functional dependence on the energy-momentum dictated by the invariance under a space inversion or a time reversal.

L’« histoire véritable de la planète Mars » 

Carnets, 2014
The definition of « foreigner » is unavoidably connected with the definition of « space ». The foreigner is a person who is, first of all, « strange » to a political space, to a physical space, our space.

Quasi-hermitian Quantum Mechanics in Phase Space [PDF]

, 2007
We investigate quasi-hermitian quantum mechanics in phase space using standard deformation quantization methods: Groenewold star products and Wigner transforms.

Big Bang, Blowup, and Modular Curves: Algebraic Geometry in Cosmology [PDF]

, 2014
We introduce some algebraic geometric models in cosmology related to the "boundaries" of space-time: Big Bang, Mixmaster Universe, Penrose's crossovers between aeons.

L’ambivalence de l’imaginaire du souterrain urbain

Géographie et Cultures, 2018
Underground spaces raise anxieties and fears that are linked to a highly unfavorable imagination. Our contribution aims to establish the major cardinals points of the imaginary of the deep-underground based on the French anthropology of the imaginaire ...

Maximizing the symmetry of Maxwell’s equations

Frontiers in Physics
Maxwell’s equations can be successfully extended to electromagnetic fields having three complex-valued components rather than their usual three real-valued components.

Closed Strings as Imaginary D-branes

, 2003
Sen has recently drawn attention to an exact time-dependent Boundary Conformal Field Theory with the space-time interpretation of brane creation and annihilation. An interesting limit of this BCFT is formally equivalent to an array of D-branes located in
