Husband R, Liermann H, McHardy J, McWilliams R, Goncharov A, Prakapenka V, et al.
Nat Commun . 2024 Sep; 15(1):8256. PMID: 39313509
HO transforms to two forms of superionic (SI) ice at high pressures and temperatures, which contain highly mobile protons within a solid oxygen sublattice. Yet the stability field of both...

Haurie L, Grandadam M, Pangburn E, Banerjee A, Burdin S, Pepin C
J Phys Condens Matter . 2024 Jan; 36(25). PMID: 38215481
We use the composite operator method (COM) to analyze the strongly correlated repulsive Hubbard model, investigating the effect of nearest-neighbor hoppings up to fourth order on a square lattice. We...

Pepin C, Souala F, By E, Berar M, Arvieux C, Fily F
Infect Dis Now . 2020 Oct; 51(2):205-208. PMID: 33075404
Objectives: To characterize awareness of Chlamydia trachomatis infection among persons consulting in a screening center in Ille-et-Vilaine, France, as well as the missed opportunities for screening in a primary health...

Morice C, Chakraborty D, Montiel X, Pepin C
J Phys Condens Matter . 2018 Jun; 30(29):295601. PMID: 29947331
Topological states of matter are at the root of some of the most fascinating phenomena in condensed matter physics. Here we argue that skyrmions in the pseudo-spin space related to...

Montiel X, Kloss T, Pepin C
Sci Rep . 2017 Jun; 7(1):3477. PMID: 28615633
Understanding the pseudo-gap phase which opens in the under-doped regime of cuprate superconductors is one of the most enduring challenges of the physics of these compounds. A depletion in the...

Kloss T, Montiel X, de Carvalho V, Freire H, Pepin C
Rep Prog Phys . 2016 Jul; 79(8):084507. PMID: 27427401
We review the recent developments in the field of cuprate superconductors with special focus on the recently observed charge order in the underdoped compounds. We introduce new theoretical developments following...

Paul I, Pepin C, Norman M
Phys Rev Lett . 2013 Feb; 110(6):066402. PMID: 23432282
Single band theories of quantum criticality successfully describe a single-particle lifetime with non-Fermi liquid temperature dependence, but they fail to obtain a charge transport rate with the same dependence unless...

Pepin C, Norman M, Burdin S, Ferraz A
Phys Rev Lett . 2011 Apr; 106(10):106601. PMID: 21469819
We argue that near a Kondo breakdown critical point, a spin liquid with spatial modulations can form. Unlike its uniform counterpart, we find that this occurs via a second order...

Benlagra A, Kim K, Pepin C
J Phys Condens Matter . 2011 Mar; 23(14):145601. PMID: 21427476
Scaling expressions for the free energy are derived, using the Luttinger-Ward (LW) functional approach in the Eliashberg framework, for two different models of the quantum critical point (QCP). First, we...

Kim K, Pepin C
J Phys Condens Matter . 2011 Mar; 22(2):025601. PMID: 21386259
We develop the quantum Boltzmann equation approach for the Kondo breakdown quantum critical point, involved with two bands for conduction electrons and localized fermions. Particularly, the role of vertex corrections...
