Finding the ground state of a lattice gauge theory with fermionic tensor networks: a $2+1d$ $\mathbb{Z}_2$ demonstration [PDF]
Phys. Rev. D 107, 014505 (2023), 2022 Tensor network states, and in particular Projected Entangled Pair States (PEPS) have been a strong ansatz for the variational study of complicated quantum many-body systems, thanks to their built-in entanglement entropy area law. In this work, we use a special kind of PEPS - Gauged Gaussian Fermionic PEPS (GGFPEPS) to find the ground state of $2+1d ...

Journal of Experimental & Clinical Cancer Research, 2019 Background The transfer of whole mitochondria that occurs during cell contact has been found to support cancer progression. However, the regulatory role of mitochondria alone is difficult to elucidate due to the complex microenvironment.

PEP for HIV prevention: are we missing opportunities to reduce new infections?
Journal of the International AIDS Society, 2022 There is newfound optimism for global efforts to reduce the estimated 1.7 million new HIV infections still occurring every year with expanded pre-exposure prophylaxis (PrEP) access and newer biomedical prevention options on the horizon [1].

Proceedings of the National Academy of Sciences of the United States of America, 2006 Bacterial transport of many sugars, coupled to their phosphorylation, is carried out by the phosphoenolpyruvate (PEP):sugar phosphotransferase system and involves five phosphoryl group transfer reactions.

Biochemistry, 1991 The mannitol transport protein (EIImtl) carries out translocation with concomitant phosphorylation of mannitol from the periplasm to the cytoplasm, at the expense of phosphoenolpyruvate (PEP).

Twisted Injectivity in PEPS and the Classification of Quantum Phases [PDF]
Ann. Phys. 351, 447-476 (2014), 2013 We introduce a class of projected entangled pair states (PEPS) which is based on a group symmetry twisted by a 3-cocycle of the group. This twisted symmetry gives rise to a new standard form for PEPS from which we construct a family of local Hamiltonians which are gapped, frustration-free and include fixed points of the renormalization group flow ...

Proceedings of the National Academy of Sciences of the United States of America, 1996 The bacterial phosphoenolpyruvate/glycose phosphotransferase system (PTS) comprises a group of proteins that catalyze the transfer of the phosphoryl group from phosphoenolpyruvate (PEP) to sugars concomitant with their translocation.

Interplay of $SU(2)$, point group and translation symmetry for PEPS: application to a chiral spin liquid [PDF]
Phys. Rev. B 98, 085151 (2018), 2018 Projected entangled pair states (PEPS) provide exact representations for many non-chiral topologically ordered states whereas their range of applicability to interacting chiral topological phases remains largely unsettled. In this context, the symmetries of the local PEPS tensors are crucial for determining the characteristic topological features of ...

Pore-blockade Times for Field-Driven Polymer Translocation [PDF]
J. Phys.: Condens. Matter 20, 095224 (2008), 2007 We study pore blockade times for a translocating polymer of length $N$, driven by a field $E$ across the pore in three dimensions. The polymer performs Rouse dynamics, i.e., we consider polymer dynamics in the absence of hydrodynamical interactions. We find that the typical time the pore remains blocked during a translocation event scales as $\sim N ...
