Spin-foams for all loop quantum gravity

- W. Kami'nski, M. Kisielowski, J. Lewandowski
- Physics
- 4 September 2009

The simplicial framework of Engle–Pereira–Rovelli–Livine spin-foam models is generalized to match the diffeomorphism invariant framework of loop quantum gravity. The simplicial spin-foams are… Expand

The flat FRW model in LQC: self-adjointness

- W. Kami'nski, J. Lewandowski
- Physics
- 19 September 2007

The flat Friedman?Robertson?Walker (FRW) model coupled to the massless scalar field according to the improved, background scale-independent version of Ashtekar, Paw?owski and Singh [1] is considered.… Expand

SL(2,C) Chern–Simons theory, a non-planar graph operator, and 4D quantum gravity with a cosmological constant: Semiclassical geometry

- Hal M. Haggard, M. Han, W. Kami'nski, A. Riello
- Physics, Mathematics
- 23 December 2014

Abstract We study the expectation value of a nonplanar Wilson graph operator in SL ( 2 , C ) Chern–Simons theory on S 3 . In particular we analyze its asymptotic behavior in the double-scaling limit… Expand

Quantum collapse rules from the maximum relative entropy principle

- F. Hellmann, W. Kami'nski, Ryszard Pawel Kostecki
- Mathematics, Physics
- 29 July 2014

We show that the von Neumann--Lueders collapse rules in quantum mechanics always select the unique state that maximises the quantum relative entropy with respect to the premeasurement state, subject… Expand

The EPRL intertwiners and corrected partition function

- W. Kami'nski, M. Kisielowski, J. Lewandowski
- Physics
- 3 December 2009

Do the SU(2) intertwiners parametrize the space of the Engle, Pereira, Rovelli, Livine (EPRL) solutions to the simplicity constraint? What is the complete form of the partition function written in… Expand

Operator spin foam models

- B. Bahr, F. Hellmann, W. Kami'nski, M. Kisielowski, J. Lewandowski
- Physics
- 22 October 2010

The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as the main tool. An… Expand

Complex Surface Diffusion Mechanisms of Cobalt Phthalocyanine Molecules on Ag(100).

- G. Antczak, W. Kami'nski, A. Sabik, C. Zaum, K. Morgenstern
- Chemistry, Medicine
- Journal of the American Chemical Society
- 19 November 2015

We used time-lapsed scanning tunneling microscopy between 43 and 50 K and density functional theory (DFT) to explore the basic surface diffusion steps of cobalt phthalocyanine (CoPc) molecules on the… Expand

Room temperature discrimination of adsorbed molecules and attachment sites on the Si(111)-7 × 7 surface using a qPlus sensor.

- Z. Majzik, B. Drevniok, W. Kami'nski, M. Ondráček, A. McLean, P. Jelínek
- Chemistry, Medicine
- ACS nano
- 5 March 2013

In this paper, we show that simultaneous noncontact atomic force microscopy (nc-AFM) and scanning tunneling microscopy (STM) is a powerful tool for molecular discrimination on the Si(111)-7 × 7… Expand

Mechanical Response and Energy-Dissipation Processes in Oligothiophene Monolayers Studied with First-Principles Simulations

- W. Kami'nski, R. P'erez
- Materials Science
- 28 July 2010

We present an extensive first-principles study of the interaction between a silicon oxide nanoasperity and a sexithiophene monolayer in order to investigate the individual molecular processes… Expand

Discretization independence implies non-locality in 4D discrete quantum gravity

- B. Dittrich, W. Kami'nski, Sebastian Steinhaus
- Physics
- 21 April 2014

The 4D Regge action is invariant under 5?1 and 4?2 Pachner moves, which define a subset of (local) changes of the triangulation. Given this fact, one might hope to find a local path integral measure… Expand
